Preventing and Managing Diabetic Complications: Practical Strategies for Better Health

by

Table of Contents

Living with diabetes requires a comprehensive approach to health management that goes far beyond simply monitoring blood sugar levels. Diabetes can affect almost every part of your body, including your heart, eyes, kidneys, and nerves, and is also linked to some types of cancer. The good news is that with proper management strategies, education, and lifestyle modifications, people with diabetes can significantly reduce their risk of developing serious complications and maintain a high quality of life. This comprehensive guide explores evidence-based strategies for preventing and managing diabetic complications, empowering you to take control of your health.

Understanding Diabetic Complications: Why Prevention Matters

The duration of glycemic burden is a strong predictor of adverse outcomes. When blood sugar levels remain elevated over extended periods, they can damage blood vessels and nerves throughout the body, leading to both macrovascular complications (affecting large blood vessels) and microvascular complications (affecting small blood vessels). Type 2 diabetes frequently goes undiagnosed for many years, because hyperglycemia develops gradually and, at earlier stages, may not be accompanied by classic symptoms and signs of hyperglycemia, such as blurry vision, dehydration, or unintentional weight loss. People with undiagnosed diabetes are exposed to variable degrees of untreated hyperglycemia and are at increased risk of developing macrovascular and microvascular complications.

The most common diabetic complications include cardiovascular disease, chronic kidney disease, diabetic retinopathy (eye damage), diabetic neuropathy (nerve damage), and diabetic foot problems. Understanding these risks is the first step toward effective prevention. Prevention of progression from prediabetes to diabetes resulted in lower rates of developing retinopathy and nephropathy. This underscores the critical importance of early intervention and consistent management.

The Foundation: Blood Sugar Control and Monitoring

Maintaining blood sugar levels within target ranges is the cornerstone of diabetes management and complication prevention. The landmark Diabetes Control and Complications Trial (DCCT) showed that participants with type 1 diabetes who kept their blood glucose levels close to normal greatly lowered their chances of developing eye, kidney, and nerve disease. This groundbreaking research demonstrated the profound impact that tight glycemic control can have on long-term health outcomes.

Understanding Blood Sugar Targets

A blood sugar target is the range you try to reach as much as possible. These are typical targets: Before a meal: 80 to 130 mg/dL. Two hours after the start of a meal: Less than 180 mg/dL. However, it’s important to note that your blood sugar targets may be different depending on your age, any additional health problems you have, and other factors. Talk to your health care team about which targets are best for you.

The A1C test is another crucial measurement tool. The A1C test shows your average blood glucose level over the last 3 months. This test is done at a health care professional’s office or lab. By measuring how much glucose (also called blood sugar) is attached to the oxygen-carrying protein in your red blood cells, this test gives you and your health-care provider a picture of your average blood glucose levels over three months.

Modern Monitoring Technologies

Recommended use of continuous glucose monitoring at diabetes onset and anytime thereafter to improve outcomes for anyone who could benefit from its use in diabetes management represents a significant advancement in diabetes care. People who take insulin to manage their diabetes may benefit from using a continuous glucose monitor (CGM). A CGM uses a sensor inserted under the skin to measure your blood sugar every few minutes. Many CGM systems have alarms and warnings that let you know if your glucose level is too low or too high.

CGM use at the onset of diabetes for those who use insulin, and for anyone at risk of hypoglycemia or who would benefit from CGM in supporting blood sugar management. The ADA also emphasizes that CGM systems are most effective when paired with education and ongoing support. These devices provide real-time data that allows for more precise adjustments to diet, exercise, and medication, ultimately leading to better glycemic control and reduced complication risk.

Traditional blood glucose meters remain important tools as well. Use a blood sugar meter (also called a glucometer) or a continuous glucose monitor (CGM) to check your blood sugar. A blood sugar meter measures the amount of sugar in a small sample of blood, usually from your fingertip. A CGM uses a sensor inserted under the skin to measure your blood sugar every few minutes. If you use a CGM, you’ll still need to test daily with a blood sugar meter.

Nutrition Strategies for Diabetes Management

Diet plays a pivotal role in managing diabetes and preventing complications. The relationship between food and blood sugar is complex, but understanding key principles can help you make informed choices that support stable glucose levels and overall health.

Evidence-Based Eating Patterns

Recommendation 3.4 was revised to focus on eating patterns with the strongest evidence base for preventing type 2 diabetes, including Mediterranean and low carbohydrate eating patterns. These dietary approaches have demonstrated significant benefits for blood sugar control and cardiovascular health. The Mediterranean diet emphasizes whole grains, vegetables, fruits, legumes, nuts, olive oil, and fish, while limiting red meat and processed foods.

Eat meals with lots of vegetables, fruits, whole grains, beans, nuts, and lean proteins like fish and seafood. Drink plenty of water. Water can help maintain healthy blood sugar levels. This balanced approach provides essential nutrients while supporting stable blood glucose levels throughout the day.

Understanding Carbohydrates and Glycemic Impact

Carbs in food make your blood sugar levels go higher after you eat them than when you eat proteins or fats. You can still eat carbs if you have diabetes. The amount you can have depends on your age, weight, activity level, and other factors. Counting carbs in foods and drinks is an important tool for managing blood sugar levels.

Not all carbohydrates affect blood sugar equally. The GI divides foods into low, medium, and high GI scores and ranks them on a scale of 0 to 100. Low GI foods have a ranking of 55 or lower. Consistently eating low GI foods may reduce blood sugar levels in people with diabetes. Low glycemic index foods cause a slower, more gradual rise in blood sugar compared to high GI foods.

Fruits, vegetables and whole grains are full of nutrients. They have fiber that helps keep blood sugar levels more stable too. Fiber is particularly beneficial because fiber slows carb digestion and sugar absorption, promoting a more gradual rise in blood sugar levels. When people with diabetes increase the fiber in their diet, they can potentially lower blood glucose over a period of 12 weeks or less, according to a major review of 15 studies. Most people—with or without diabetes—don’t get the recommended 21 to 38 grams of fiber daily. (The American Diabetes Association suggests that diabetics should aim for 14 grams of fiber for every 1,000 calories consumed in a day.)

Practical Meal Planning Strategies

Two common ways to plan meals are carbohydrate counting and the plate method. The plate method is particularly user-friendly for many people. The plate method helps you eat a healthy balance of foods and control portion sizes. This approach typically involves filling half your plate with non-starchy vegetables, one-quarter with lean protein, and one-quarter with whole grains or starchy vegetables.

Leafy greens such as romaine, kale, and spinach, along with non-starchy vegetables (for example, peppers, tomatoes, and onions) are high in fiber, low in calories, and nutrient-rich. O’Meara suggests filling at least half your plate with vegetables and eating them early in the meal. You’ll feel full faster and not overeat carbs.

For those who prefer more precise tracking, carbohydrate counting offers detailed control. Counting carbs involves keeping track of how many grams of carbohydrates you eat and drink during the day. If you take diabetes medicine called insulin at mealtimes, it’s important to know the amount of carbohydrates in foods and drinks. That way, you can take the right dose of insulin.

Foods to Emphasize and Limit

Aim to eat smaller portion sizes and choose foods lower in fat, sugar and salt. The American Diabetes Associations recommends diabetes-friendly foods like avocados, leafy greens, berries and nuts. These nutrient-dense foods provide vitamins, minerals, healthy fats, and antioxidants that support overall health while helping to manage blood sugar.

Whole grains such as whole wheat bread and pasta, brown rice, oats, and quinoa are an excellent source of fiber. Fiber acts like an outer shell covering these carbs. That shell has to be broken down, so there’s a slight delay in the flow of sugars into the bloodstream. Whole grains not only help control diabetes but can help lower cholesterol and prevent other chronic diseases.

Conversely, certain foods should be limited. Eat fewer refined, highly processed carbs. These include white bread, white rice, sugary cereal, cakes, cookies, candy and chips. Limit sugary foods and drinks, red meats, processed meats, salty snacks, and foods that are highly processed. These foods can cause rapid blood sugar spikes and provide little nutritional value.

Physical Activity: A Powerful Tool for Complication Prevention

Regular physical activity is one of the most effective strategies for managing diabetes and preventing complications. Exercise offers multiple benefits that extend far beyond blood sugar control, positively impacting cardiovascular health, weight management, insulin sensitivity, and mental well-being.

How Exercise Improves Diabetes Management

Regular exercise and physical activity can help you manage your weight and increase insulin sensitivity. Increased insulin sensitivity means your cells can use the glucose in your bloodstream more effectively. This fundamental mechanism helps lower blood sugar levels both during and after exercise.

Exercise helps in two ways. Consistent activity boosts your metabolism so you are better able to burn off sugars. And if you have a high-carb meal, taking a walk immediately or participating in another activity can burn off excess sugars in the bloodstream. This dual benefit makes physical activity an invaluable tool for both long-term management and acute blood sugar control.

Exercise can help lower your risk of developing Type 2 diabetes. It can also help you manage diabetes if you are living with it. Exercise also improves your energy, mood, and clears your mind. These psychological and emotional benefits are particularly important, as living with a chronic condition can be mentally challenging.

While specific recommendations should be individualized based on your current fitness level, health status, and personal preferences, general guidelines suggest aiming for at least 150 minutes of moderate-intensity aerobic activity per week, spread across several days. This could include brisk walking, swimming, cycling, or dancing. Additionally, incorporating resistance training exercises at least two days per week can help build muscle mass, which improves insulin sensitivity and glucose metabolism.

Exercise often to help relieve stress and lower your blood sugar. Even small amounts of activity can make a difference. If you’re new to exercise or have been inactive, start slowly and gradually increase the duration and intensity of your workouts. Always consult with your healthcare provider before beginning a new exercise program, especially if you have existing complications or other health conditions.

Medical Management and Pharmacological Approaches

While lifestyle modifications form the foundation of diabetes management, medications play a crucial role in achieving and maintaining optimal blood sugar control and preventing complications. Recent advances in diabetes pharmacotherapy have introduced medications that not only lower blood sugar but also provide additional protective benefits for the heart, kidneys, and other organs.

Modern Medication Strategies

Glucose-lowering medications have emerged as a promising way to treat diabetes and common comorbidities such as cardiovascular, liver, and kidney disease, or obesity concurrently. The 2026 SOC provides increased guidance on treatment and dosing for medications, including glucagon-like peptide-1 receptor agonists (GLP-1s) and metformin.

In addition to managing blood sugar, blood pressure, and cholesterol levels, recommendations include using GLP-1 and similar medicines (such as Ozempic and Mounjaro) and SGLT-2 inhibitors (like Jardiance and Farxiga) in type 2 diabetes, which provide benefits beyond glucose control, including protection for the heart and kidneys. These medications represent a paradigm shift in diabetes treatment, addressing multiple aspects of the disease simultaneously.

New guidance on glucose-lowering therapies in people with chronic kidney disease, including use by those on dialysis · Additional guidance on the use of glucose-lowering therapy beyond obesity and glycemic treatment, including heart, kidney, and liver health benefits demonstrates the expanding understanding of how diabetes medications can protect against complications.

Medication Adherence and Management

Taking diabetes medicines is often part of managing diabetes. The medicines you take depend on your type of diabetes, how well medicines control your blood glucose level, and other health conditions you may have. You may also need medicines to help manage blood pressure or cholesterol levels.

In diabetes, individuals need to adapt to a plan and follow it strictly. This plan should comprise many behavioral changes and actions to take care of diabetes on a regular, day-to-day basis. All these changes and actions should comprise positive lifestyle changes, which include dietary planning and regular physical exercise; taking proper medications daily, which comprise insulin or oral medications that act as hypoglycemic agents as and when indicated; keeping an eye on blood sugar levels; managing symptoms related to diabetes mellitus; undertaking guidelines related to foot care; and taking care of diabetes or other problems related to health.

Medication adherence is critical for preventing complications. Work closely with your healthcare team to understand your medications, their purposes, proper dosing schedules, and potential side effects. If you experience difficulties with your medication regimen—whether due to side effects, cost, or complexity—communicate openly with your healthcare provider to explore alternatives or solutions.

Cardiovascular Disease Prevention in Diabetes

People with diabetes are two to four times more likely to have heart disease or a stroke than those without this chronic condition. Cardiovascular disease represents the leading cause of morbidity and mortality among people with diabetes, making cardiovascular risk reduction a critical component of comprehensive diabetes care.

Understanding Cardiovascular Risk

ASCVD broadly refers to a history of acute coronary syndrome, myocardial infarction (MI), stable or unstable angina or coronary or other arterial revascularization, stroke, or peripheral artery disease (PAD) including aortic aneurysm and is the leading cause of morbidity and mortality in people with diabetes. Diabetes itself confers independent ASCVD risk, and among people with diabetes, all major cardiovascular risk factors, including hypertension, hyperlipidemia, and obesity, are clustered and common.

The new guidelines take a broader approach to long-term health, recognizing that heart disease, kidney disease, and diabetes as interconnected conditions that require coordinated approaches for prevention and treatment. This holistic perspective acknowledges that managing diabetes effectively requires addressing all cardiovascular risk factors simultaneously.

Blood Pressure Management

Hypertension is extremely common among people with diabetes and significantly increases cardiovascular risk. Restricting sodium intake (<2,300 mg/day), increasing consumption of fruits and vegetables (8–10 servings per day) and low-fat dairy products or nondairy alternatives (2–3 servings per day), avoiding excessive alcohol consumption (no more than 2 servings per day in men and no more than 1 serving per day in women) can help manage blood pressure through dietary modifications.

The DASH (Dietary Approaches to Stop Hypertension) eating pattern has demonstrated particular effectiveness for blood pressure reduction in people with diabetes. Regular blood pressure monitoring and medication adherence when prescribed are essential for maintaining target blood pressure levels and reducing cardiovascular risk.

Cholesterol and Lipid Management

Dyslipidemia, or abnormal cholesterol levels, is another major cardiovascular risk factor in diabetes. Moderate-intensity statin therapy is recommended in people with diabetes who are ≥75 years of age. However, the risk-benefit profile should be routinely evaluated in this population, with downward titration of dose performed as needed.

For many people with diabetes, statin therapy is recommended for primary prevention of cardiovascular disease, particularly in those with additional risk factors. The specific intensity of statin therapy and target LDL cholesterol levels should be individualized based on age, existing cardiovascular disease, and overall risk profile. Regular lipid panel testing allows healthcare providers to monitor treatment effectiveness and adjust therapy as needed.

Protecting Kidney Health: Preventing Diabetic Nephropathy

Diabetic kidney disease, or diabetic nephropathy, is one of the most serious complications of diabetes and a leading cause of kidney failure requiring dialysis or transplantation. In people with diabetes, CKD significantly increases the risk of CVD and mortality. Early detection and intervention are crucial for slowing or preventing progression of kidney disease.

Screening and Early Detection

The updated guidelines recommend that most people with diabetes get kidney tests at least once a year, including a urine test for protein and a blood test to estimate kidney function. These tests can detect kidney damage in its earliest stages, when interventions are most effective at preventing progression.

The urine albumin-to-creatinine ratio (UACR) test detects small amounts of protein in the urine, an early sign of kidney damage. The estimated glomerular filtration rate (eGFR) blood test measures how well the kidneys are filtering waste from the blood. Together, these tests provide a comprehensive picture of kidney health and function.

Protective Strategies for Kidney Health

Maintaining optimal blood sugar and blood pressure control represents the foundation of kidney protection in diabetes. Additionally, certain medications offer specific kidney-protective benefits. SGLT-2 inhibitors and GLP-1 receptor agonists have demonstrated significant benefits in slowing the progression of diabetic kidney disease, even beyond their glucose-lowering effects.

Lifestyle modifications also play an important role in kidney health. Limiting sodium intake, staying well-hydrated, avoiding nephrotoxic medications when possible, and maintaining a healthy weight all contribute to kidney protection. If you have existing kidney disease, working with a nephrologist in addition to your diabetes care team ensures comprehensive management.

Preserving Vision: Diabetic Retinopathy Prevention

Diabetic retinopathy is a leading cause of vision loss and blindness among working-age adults. This complication develops when high blood sugar levels damage the blood vessels in the retina, the light-sensitive tissue at the back of the eye. Early detection through regular screening and proactive management can prevent or delay vision loss in most cases.

The Importance of Regular Eye Examinations

Routine comprehensive dilated eye examinations are essential for all people with diabetes. These examinations allow eye care professionals to detect retinopathy in its earliest stages, often before any symptoms appear. For people with type 1 diabetes, the first eye exam should occur within five years of diagnosis. For those with type 2 diabetes, an eye exam should be performed at the time of diagnosis, as the disease may have been present for years before detection.

The frequency of subsequent eye exams depends on the presence and severity of retinopathy. People without retinopathy may be screened every one to two years, while those with existing retinopathy require more frequent monitoring. Pregnant women with diabetes should have an eye exam in the first trimester and be monitored closely throughout pregnancy and the postpartum period.

Recent Developments in Eye Health Management

The narrative was expanded to discuss the effect of GLP-1 RA treatment on eye health, including nonarteritic anterior ischemic optic neuropathy, glaucoma, neovascular age-related macular degeneration, and diabetic retinopathy progression. The role of adjunctive therapies was broadened to emphasize a holistic, multifactorial approach to eye health in diabetes.

Optimal blood sugar control remains the most important factor in preventing diabetic retinopathy. Blood pressure control and lipid management also contribute to eye health. If retinopathy develops, various treatments are available, including laser therapy, anti-VEGF injections, and in advanced cases, vitrectomy surgery. Early intervention with these treatments can preserve vision and prevent progression to more severe stages.

Diabetic Neuropathy: Protecting Your Nervous System

Diabetic neuropathy refers to nerve damage caused by diabetes and represents one of the most common complications of the disease. It can affect nerves throughout the body, leading to a wide range of symptoms and potential complications. The most common form is peripheral neuropathy, which affects the feet and legs, but diabetes can also damage nerves controlling the heart, digestive system, bladder, and other organs.

Types and Symptoms of Diabetic Neuropathy

Peripheral neuropathy typically begins with symptoms in the feet and legs, including numbness, tingling, burning sensations, sharp pains, or increased sensitivity to touch. These symptoms often worsen at night and can significantly impact quality of life and sleep. Loss of sensation in the feet is particularly concerning, as it increases the risk of unnoticed injuries that can lead to serious infections and ulcers.

Autonomic neuropathy affects the nerves controlling involuntary body functions and can cause digestive problems (gastroparesis), bladder dysfunction, sexual dysfunction, abnormal sweating, and dangerous drops in blood pressure upon standing. Cardiovascular autonomic neuropathy can affect heart rate regulation and increase the risk of silent heart attacks.

Screening and Management

Neuropathy diagnosis discussion was updated to align more closely with the “Foot Care” subsection, incorporating the Ipswich touch test. Regular screening for neuropathy should begin at diagnosis for people with type 2 diabetes and within five years of diagnosis for those with type 1 diabetes. Screening typically includes assessment of symptoms, examination of the feet, and testing of sensation using monofilament testing and vibration perception.

Recommendation 12.22 was updated to emphasize the importance of combination therapy for additional relief of neuropathic pain. While preventing neuropathy through optimal blood sugar control is ideal, various treatments can help manage symptoms and prevent progression once neuropathy develops. These include medications for neuropathic pain, topical treatments, physical therapy, and careful foot care.

Diabetic Foot Care: Prevention and Early Intervention

Foot complications represent some of the most serious and potentially devastating consequences of diabetes. The combination of neuropathy (which reduces sensation) and peripheral artery disease (which impairs blood flow) creates a perfect storm for foot problems. Minor injuries can quickly escalate into serious infections, ulcers, and in severe cases, may lead to amputation. However, most diabetic foot complications are preventable through proper care and early intervention.

Daily Foot Care Practices

The narrative was strengthened regarding prevention and management of diabetic foot complications. A comprehensive daily foot care routine is essential for everyone with diabetes. This includes:

  • Inspecting feet daily for cuts, blisters, redness, swelling, or nail problems, using a mirror if necessary to see the bottoms of feet
  • Washing feet daily with lukewarm water and mild soap, drying thoroughly, especially between toes
  • Moisturizing feet to prevent dry, cracked skin, but avoiding application between toes
  • Trimming toenails straight across and filing sharp edges
  • Wearing clean, dry socks and changing them daily
  • Never walking barefoot, even indoors
  • Wearing properly fitted shoes that don’t cause pressure points or rubbing
  • Checking inside shoes before wearing them for foreign objects or rough areas

Professional Foot Care and Screening

In addition to daily self-care, regular professional foot examinations are crucial. Healthcare providers should perform a comprehensive foot examination at least annually for all people with diabetes, and more frequently for those with risk factors such as neuropathy, peripheral artery disease, foot deformities, or a history of foot ulcers or amputation.

These examinations assess sensation, pulses, skin integrity, and structural abnormalities. People at high risk may benefit from specialized footwear, custom orthotics, or referral to a podiatrist for ongoing care. Any foot injury, no matter how minor it seems, should be evaluated promptly by a healthcare provider, as early intervention can prevent serious complications.

Weight Management and Diabetes Complications

Weight management plays a crucial role in diabetes prevention and management, with even modest weight loss providing significant health benefits. For people with type 2 diabetes or prediabetes, achieving and maintaining a healthy weight can improve blood sugar control, reduce cardiovascular risk factors, and in some cases, lead to diabetes remission.

The Impact of Weight Loss on Diabetes

In a nationwide study of 5,145 people with type 2 diabetes, those who shed just 5 to 10 percent of their weight (for someone weighing 175 pounds, that’s a loss of 9 to 17.5 pounds) were three times more likely to lower their A1C (a test of long-term blood sugar control) by 0.5 percent, a significant drop. They were also 50 percent more likely to lower their blood pressure by 5 points and twice as likely to lower their triglycerides by 40 points compared with those whose weight remained the same.

These findings demonstrate that you don’t need to achieve dramatic weight loss to experience meaningful health improvements. Recommendation 3.3 was clarified to recommend referral of individuals with overweight or obesity at high risk for type 2 diabetes to a diabetes prevention program with the goal of achieving and maintaining weight reduction of at least 5–7% of initial body weight.

Strategies for Sustainable Weight Management

Successful weight management requires a comprehensive approach that combines dietary modifications, increased physical activity, behavioral strategies, and in some cases, medication or surgical interventions. The key is finding sustainable strategies that fit your lifestyle, preferences, and individual circumstances.

Stay at a healthy weight to help prevent, delay or manage diabetes. Speak to a health care professional to understand what is a healthy weight for you. Working with a registered dietitian, diabetes educator, or weight management specialist can provide personalized guidance and support for achieving your weight goals.

Behavioral strategies such as self-monitoring, goal-setting, problem-solving, and stress management enhance the effectiveness of dietary and physical activity interventions. Support from family, friends, or structured programs can also improve long-term success. Remember that weight management is a marathon, not a sprint—focus on gradual, sustainable changes rather than quick fixes.

Mental Health and Diabetes Management

Living with diabetes can take a significant toll on mental and emotional well-being. The constant demands of disease management, fear of complications, and the burden of living with a chronic condition can lead to diabetes distress, anxiety, depression, and other mental health challenges. Addressing these psychological aspects is essential for comprehensive diabetes care and complication prevention.

Understanding Diabetes Distress

Feeling stressed, sad, or angry can be common for people with diabetes. Many people with chronic, or long-term, illnesses such as diabetes develop anxiety or other mental health conditions. Learn healthy ways to lower your stress, and ask for help from your health care team or a mental health professional.

Guidance on behavioral health screening and referral for concerns such as diabetes distress and anxiety reflects the growing recognition of mental health’s importance in diabetes care. Diabetes distress differs from clinical depression and refers specifically to the emotional burden and worry related to managing diabetes. It can manifest as feeling overwhelmed by diabetes demands, frustrated with blood sugar levels, or worried about complications.

Stress Management and Coping Strategies

It’s very important to take charge of stress when you have diabetes. The hormones your body makes in response to prolonged stress may cause your blood sugar to rise. It also may be harder to closely follow your usual routine to manage diabetes if you’re under a lot of extra pressure.

Stress can affect your blood sugar levels. When stressed, your body secretes hormones called glucagon and cortisol, which cause blood sugar levels to rise. Mindfulness-based stress reduction, may also help correct insulin secretion problems among people with chronic diabetes receiving medical treatment.

Effective stress management techniques include mindfulness meditation, deep breathing exercises, progressive muscle relaxation, yoga, regular physical activity, adequate sleep, and engaging in enjoyable hobbies. Learn relaxation techniques, rank tasks in order of importance and set limits. Whenever you can, stay away from things that cause stress for you. Exercise often to help relieve stress and lower your blood sugar.

The Importance of Sleep

Getting enough sleep may improve your mood, energy level, and blood glucose level. Most adults should aim for about 7 to 8 hours each night. Children and adolescents may need more sleep. When you get enough sleep, you have more energy and can be more active. Plus, studies indicate that poor sleep is linked to higher sugar levels.

Prioritizing sleep hygiene—maintaining a consistent sleep schedule, creating a comfortable sleep environment, limiting screen time before bed, and avoiding caffeine and large meals close to bedtime—can improve both sleep quality and diabetes management.

Preventive Care and Health Maintenance

Comprehensive preventive care extends beyond diabetes-specific monitoring to include general health maintenance that reduces overall disease burden and improves quality of life. A proactive approach to preventive care can identify potential problems early and prevent complications before they develop.

Immunizations and Infection Prevention

People with diabetes face increased risk of certain infections and may experience more severe illness when infections occur. Staying current with recommended vaccinations is an important but often overlooked aspect of diabetes care. Recommendation 4.5, regarding vaccinations, was revised to include adolescents.

Recommended vaccinations for people with diabetes include annual influenza vaccines, pneumococcal vaccines, hepatitis B vaccine series, Tdap (tetanus, diphtheria, pertussis) boosters, and COVID-19 vaccines as recommended. Discuss your vaccination status with your healthcare provider to ensure you’re adequately protected.

Dental Health

Diabetes increases the risk of gum disease (periodontitis), which in turn can make blood sugar control more difficult, creating a vicious cycle. Regular dental care, including professional cleanings and examinations at least twice yearly, is essential. Daily oral hygiene practices—brushing twice daily, flossing daily, and using antimicrobial mouthwash—help prevent dental complications.

Inform your dentist about your diabetes diagnosis and current blood sugar control. If you notice signs of gum disease such as red, swollen, or bleeding gums, persistent bad breath, or loose teeth, seek dental care promptly. Good dental health contributes to overall health and better diabetes management.

Smoking Cessation

Nearly one in six people with diabetes are smokers. Tobacco use boosts your risk for heart disease, stroke, blood sugar control problems, vision loss, nerve damage, kidney problems, and even amputation. If you smoke, quitting is also important. Managing your ABCs may lower your chances of having health problems from diabetes, such as a heart attack, stroke, kidney disease, blindness, and foot or leg amputations.

Avoid smoking, vaping, nicotine pouches or using tobacco. It makes it harder to manage prediabetes and diabetes. Even being around secondhand smoke can cause problems. If you’ve tried to quit in the past, make another attempt. Counseling or a support group plus nicotine-replacement products and medications to help control nicotine cravings can help.

Building Your Diabetes Care Team

Effective diabetes management requires a team approach. While you are the most important member of your care team, surrounding yourself with knowledgeable healthcare professionals provides the support, expertise, and accountability needed for optimal outcomes.

Core Team Members

The SOC stresses the importance of coordinated interprofessional teams, which include physicians, diabetes educators, dietitians, pharmacists, and mental health counselors, in guiding diabetes patient care. Your primary care physician or endocrinologist typically coordinates your overall diabetes care, but other specialists play important roles.

A certified diabetes care and education specialist (CDCES) provides education on blood sugar monitoring, medication management, nutrition, physical activity, and problem-solving skills. Registered dietitian nutritionists offer personalized nutrition counseling and meal planning support. Pharmacists can help optimize medication regimens, manage side effects, and ensure proper medication use. Mental health professionals address the psychological aspects of living with diabetes.

Depending on your individual needs and any existing complications, your team might also include an ophthalmologist or optometrist for eye care, a podiatrist for foot care, a nephrologist for kidney disease, a cardiologist for heart disease, and other specialists as needed.

Diabetes Self-Management Education and Support

Ongoing diabetes self-management education and support are critical to empowering people, preventing acute complications, and reducing the risk of long-term complications. Under these guidelines, people with diabetes would also engage in diabetes self-management education and support (DSMES), and well-rounded care includes a mix of diabetes education, blood glucose monitoring, and comorbidity management.

Ask your doctor about a diabetes self-management class near you. In a 2011 study from The Johns Hopkins University, people who took diabetes-education classes saw their A1C reduced by a significant 0.72 percent. These programs provide structured education on all aspects of diabetes management and ongoing support to help you implement and maintain healthy behaviors.

DSMES programs are typically offered through hospitals, clinics, community health centers, and online platforms. Many insurance plans, including Medicare, cover DSMES services. Taking advantage of these resources can significantly improve your knowledge, skills, confidence, and health outcomes.

Technology and Innovation in Diabetes Management

Technological advances have revolutionized diabetes management, offering tools that provide greater precision, convenience, and insight into blood sugar patterns. Embracing these technologies can enhance your ability to manage diabetes effectively and prevent complications.

Continuous Glucose Monitoring Systems

As mentioned earlier, continuous glucose monitors have become increasingly accessible and are now recommended for broader populations. NIDDK supported research that helped scientists develop the first continuous glucose monitor (CGM) that was approved by the U.S. Food and Drug Administration (FDA) in 1999. CGMs, which are part of artificial pancreas systems, help people track glucose levels in real-time with fewer finger pricks.

Modern CGM systems provide continuous data on glucose levels, trends, and patterns, allowing for more informed decision-making about food, activity, and medication. Many systems include customizable alerts that warn of high or low blood sugar, helping prevent dangerous glucose excursions. The data can be shared with healthcare providers and family members, facilitating better communication and support.

Automated Insulin Delivery Systems

Some people use a CGM as part of an artificial pancreas. An artificial pancreas is a system that mimics how a healthy pancreas controls blood glucose in the body. A CGM, an insulin pump, and a software program that shares information between the CGM and insulin pump make up the artificial pancreas.

Another major milestone came in 2016, when the FDA approved a commercial “hybrid” artificial pancreas system. Other artificial pancreas systems have been approved since 2016. NIDDK continues to support research into artificial pancreas systems and other technologies that may improve diabetes management.

AID systems as the preferred insulin delivery system for all people with type 1 diabetes and children and adults with type 2 diabetes who use insulin. These systems automate much of the insulin dosing process, reducing the burden of diabetes management while improving glucose control and reducing hypoglycemia risk.

Digital Health Tools and Apps

Smartphone apps, web-based platforms, and telehealth services have expanded access to diabetes education, support, and care. Recommendation 3.6 was clarified to indicate that certified technology-assisted diabetes prevention programs can be delivered through smartphones, web-based applications, and telehealth modalities.

Digital tools can help with medication reminders, carbohydrate counting, activity tracking, appointment scheduling, and communication with healthcare providers. Many integrate with glucose meters and CGM systems to provide comprehensive data analysis and insights. While technology should complement rather than replace human interaction and professional medical care, these tools can enhance self-management capabilities and improve outcomes.

Special Considerations for Different Populations

Diabetes management strategies may need to be tailored based on age, pregnancy status, and other individual factors. Understanding these special considerations ensures that care is appropriately personalized.

Older Adults with Diabetes

Older adults face unique challenges in diabetes management, including multiple comorbidities, polypharmacy, cognitive impairment, functional limitations, and increased risk of hypoglycemia. Treatment goals and strategies should be individualized based on health status, life expectancy, and personal preferences.

For healthy older adults with good functional status and life expectancy, standard diabetes management goals may be appropriate. However, for those with multiple chronic conditions, cognitive impairment, or limited life expectancy, less stringent glycemic targets may be more appropriate to minimize hypoglycemia risk and treatment burden while maintaining quality of life.

Pregnancy and Gestational Diabetes

Pregnancy presents special considerations for diabetes management. Women with pre-existing diabetes require careful preconception planning and intensive management throughout pregnancy to optimize maternal and fetal outcomes. Gestational diabetes, which develops during pregnancy, requires screening, monitoring, and treatment to prevent complications.

Tight glycemic control during pregnancy is essential but must be balanced against the increased risk of hypoglycemia. Medication options are more limited during pregnancy, with insulin being the preferred treatment for many women. Postpartum follow-up is important, as women with gestational diabetes have increased risk of developing type 2 diabetes later in life.

Children and Adolescents

Managing diabetes in children and adolescents requires balancing glycemic control with normal growth, development, and quality of life. Family involvement is crucial, with age-appropriate transition of diabetes management responsibilities from parents to the child over time.

School and childcare settings present unique challenges that require education of staff, development of diabetes management plans, and advocacy to ensure children can participate fully in all activities. Adolescence brings additional challenges related to hormonal changes, increased independence, and psychosocial factors that can affect diabetes management.

Creating Your Personalized Action Plan

Knowledge is power, but action creates results. Taking what you’ve learned and translating it into a personalized action plan is the key to preventing diabetic complications and achieving your health goals.

Setting SMART Goals

Effective goals are Specific, Measurable, Achievable, Relevant, and Time-bound. Rather than vague intentions like “eat healthier,” set specific goals such as “eat at least three servings of vegetables daily for the next month” or “walk for 30 minutes five days per week.” Start with one or two goals and add more as you build confidence and establish new habits.

Healthy habits take time. Start with one small habit and get that one right. Then add another from there. Stay consistent and don’t get discouraged. You’re making progress every day. This incremental approach is more sustainable than attempting to overhaul your entire lifestyle at once.

Tracking Progress and Adjusting Course

Regular monitoring of blood sugar, A1C, blood pressure, weight, and other relevant metrics provides objective feedback on your progress. Keep records of your measurements, medications, meals, physical activity, and how you’re feeling. This information helps you identify patterns, troubleshoot problems, and celebrate successes.

Review your progress regularly with your healthcare team and be prepared to adjust your plan as needed. What works initially may need modification over time as your circumstances, health status, or goals change. Flexibility and willingness to adapt are important for long-term success.

Building Support Systems

You don’t have to manage diabetes alone. Support systems and available resources were added in addition to identifying care partners at the initial visit and follow-up visits as appropriate. Family members, friends, support groups, online communities, and healthcare professionals can all provide valuable support, encouragement, and accountability.

Share your goals with supportive people in your life and let them know how they can help. Consider joining a diabetes support group, either in-person or online, to connect with others who understand the challenges you face. Don’t hesitate to ask for help when you need it—seeking support is a sign of strength, not weakness.

Looking Forward: Hope and Empowerment

While diabetes is a serious chronic condition that requires ongoing attention and management, it’s important to maintain perspective and hope. Based on the latest scientific research and clinical trials, the Standards of Care includes strategies for diagnosing and treating diabetes in children, adolescents, and adults; methods to prevent or delay diabetes and its associated comorbidities like obesity; and care recommendations to enhance health outcomes. “The 2026 ‘Standards of Care in Diabetes’ represents significant advancement in the delivery of evidence-based, person-centered care. These guidelines synthesize the latest scientific research with practical clinical strategies, thereby equipping health care professionals with the tools necessary to provide optimal care for individuals living with diabetes.”

Advances in diabetes care continue to accelerate, with new medications, technologies, and treatment approaches emerging regularly. Research into diabetes prevention, treatment, and potential cures continues worldwide. The tools and knowledge available today are more sophisticated and effective than ever before, offering real hope for preventing complications and living well with diabetes.

You may be able to prevent or delay diabetes health problems by leading a healthy lifestyle, taking your medicines, and managing your blood glucose level, also called blood sugar level. Work with your health care team to create a diabetes care plan that works for you. Remember that every positive choice you make—every healthy meal, every walk, every blood sugar check—is an investment in your future health and well-being.

Living with diabetes presents challenges, but it also offers opportunities for personal growth, resilience, and taking charge of your health in meaningful ways. By implementing the strategies outlined in this guide, working closely with your healthcare team, and maintaining a proactive, positive approach, you can minimize your risk of complications and enjoy a full, active, healthy life.
