Understanding High Blood Sugar and Why It Matters
High blood sugar, or hyperglycemia, is common in people who have diabetes. A person’s blood sugar can be high when the pancreas doesn’t produce enough insulin, or if the body becomes resistant to insulin. When blood glucose levels rise too high, it can cause both immediate discomfort and serious long-term health complications if left unmanaged.
Hyperglycemia can cause immediate (acute) side effects, including thirst, frequent urination, headaches, hunger, and blurry vision. It can also make you feel tired. Beyond these immediate symptoms, chronic high blood sugar can lead to devastating complications over time.
High blood sugar, or hyperglycemia, can cause long-term health complications like cardiovascular disease, nerve damage, gum infections and even eye problems. Hyperglycemia can also damage blood vessels, thereby increasing the likelihood of heart disease, stroke and kidney disease. Understanding how to manage blood sugar levels effectively is crucial for preventing these serious health outcomes.
What Blood Sugar Levels Are Considered High?
Before discussing how to lower blood sugar, it’s important to understand what constitutes high blood sugar. A fasting blood sugar is considered to be high if it’s above 130 mg/dl. A high postprandial, or post-meal, blood sugar is one that is above 180 mg/dl two hours after eating.
According to the University of Michigan, blood sugar levels of 300 mg/dL or more can be dangerous. The university recommends to call a doctor if you have two readings in a row of 300 mg/dL or more. At extremely high levels, blood sugar becomes a medical emergency requiring immediate professional intervention.
It’s worth noting that blood sugar goals may vary from person to person based on individual health conditions, age, and other factors. Always consult with your healthcare provider to determine your specific target ranges.
When to Seek Emergency Medical Care
While many cases of elevated blood sugar can be managed at home with the strategies outlined in this article, some situations require immediate medical attention. If someone has ketones in their urine or symptoms of excessively high blood sugar, they should seek immediate medical support.
If you fail to treat hyperglycemia, a condition called ketoacidosis (diabetic coma) could occur. Ketoacidosis develops when your body doesn’t have enough insulin. Without insulin, your body can’t use glucose for fuel, so your body breaks down fats to use for energy. When your body breaks down fats, waste products called ketones are produced. Ketoacidosis is life-threatening and needs immediate treatment.
If you have any symptoms of severe hyperglycemia — even if they seem minor — check your blood sugar level right away. If your blood sugar level is 240 mg/dL (13.3 mmol/L) or above, use an over-the-counter urine ketones test kit. If the urine test is positive, your body may have started making the changes that can lead to diabetic ketoacidosis.
Signs that warrant emergency medical attention include severe confusion, weakness, nausea, vomiting, difficulty breathing, or loss of consciousness. Don’t hesitate to call 911 or go to the emergency room if you experience these symptoms.
The Fastest Way to Lower Blood Sugar: Insulin and Medication
The fastest way to lower blood sugar is by taking fast-acting insulin or your prescribed diabetes medication. Taking insulin is the fastest way to lower blood sugar (of course, only do this if you’ve been prescribed insulin and with guidance from your health care provider or diabetes educator).
If you use insulin, it’s critical to follow your healthcare provider’s instructions precisely. Never share your insulin—and on the other hand, do not use someone else’s insulin to try to lower your blood sugar. Insulin dosing is carefully determined on an individual basis by your healthcare provider.
Changes to your insulin program or a supplement of short-acting insulin can help control hyperglycemia. A supplement is an extra dose of insulin used to help temporarily correct a high blood sugar level. Work with your healthcare team to develop a clear plan for when and how to use correction doses of insulin.
If you’re diabetic and your blood sugar is elevated, it’s important to know which type of diabetes you have. Type 1 diabetes occurs when the pancreas does not produce insulin. It can only be treated with insulin given as an injection or delivered through an insulin pump. If you have Type 2 diabetes, you can usually manage high blood sugar with diet, exercise and medication.
Hydration: A Simple Yet Powerful Strategy
One of the simplest and most effective ways to help lower blood sugar is to drink plenty of water. Drinking water and staying hydrated is important for managing blood sugar, also known as blood glucose. “Water helps your kidneys filter out excess sugar through urine,” says Khan.
Water is an incredibly potent agent for reducing blood sugar. By promoting kidney function and facilitating glucose excretion through urine, staying well-hydrated can aid in decreasing high blood sugar levels quickly. Drinking plenty of water helps your kidneys flush out excess sugar.
If your blood sugar is high, you could become dehydrated. With high blood sugar, you need to take in more fluids than usual to help flush excess sugar out of the body through the urine. This creates a beneficial cycle where proper hydration supports the body’s natural mechanisms for regulating blood glucose.
Staying adequately hydrated ensures sugar in the blood does not become too concentrated, and there is some research to show a decreased risk of the development of diabetes with consistent adequate hydration. Additionally, dehydration can trigger the hormone vasopressin, which is known to raise blood sugar.
When choosing beverages, always opt for water or other sugar-free drinks. Avoid sugary drinks like fruit juices and regular sodas, because they will raise blood sugar even more. Keep a water bottle within reach throughout the day as a reminder to stay hydrated, and consult your healthcare provider about the appropriate fluid intake for your individual needs.
Physical Activity and Exercise
Exercise is one of the most effective natural methods for lowering blood sugar levels. Regular exercise can help improve your insulin sensitivity, which means your cells can better use the sugar in your blood, lowering blood sugar levels. When our muscles are working, they are actively taking sugar out of the blood to use as energy, effectively lowering blood sugar.
How Exercise Lowers Blood Sugar
Exercising or being active soon after eating will also lower your blood sugar in many ways. First of all, the glucose that doesn’t enter the bloodstream can be used for muscle use during exercise. Exercise also diverts blood flow away from the intestines, reducing glucose absorption.
Some research shows that one session of moderate exercise can have lasting positive effects on blood sugar levels for up to two days. This means that regular physical activity provides both immediate and sustained benefits for blood sugar management.
How Much Exercise Is Needed?
The good news is that you don’t need to engage in intense workouts to see benefits. It doesn’t take a lot of exercise to produce a drop in post-meal blood glucose levels. One study showed that just 15 minutes of walking after meals significantly improved glycemic control over a 24-hour period.
Light to moderate activities such as walking, stretching, swimming, or cycling can all be effective. The key is consistency and timing—exercising shortly after meals can be particularly beneficial for preventing blood sugar spikes.
Important Exercise Precautions
While exercise is generally beneficial, there are important safety considerations when blood sugar is very high. You can often lower your blood glucose level by exercising. However, if your blood glucose is above 240 mg/dl, check your urine for ketones. If you have ketones, do not exercise. Exercising when ketones are present may make your blood glucose level go even higher.
While exercise is an effective way to lower your blood sugar throughout the day, some exercises — particularly short bursts of strenuous activity — can briefly increase blood sugar levels. This is because strenuous activity activates the body’s stress response, causing a release of glucagon to power the muscles.
Always check your blood sugar before exercising, especially if you take insulin. If you experience dizziness, confusion, or other concerning symptoms during exercise, stop immediately and check your blood sugar.
Dietary Strategies to Lower Blood Sugar
What you eat plays a crucial role in blood sugar management. Although diet plays a major role in regulating your blood sugar levels, there are no specific foods that can bring down your blood sugar quickly. There are no magic foods that lower blood sugar instantly, says Dr. Redmond. However, making smart food choices can help stabilize blood sugar and prevent further spikes.
Foods to Avoid When Blood Sugar Is High
When your blood sugar is elevated, certain foods should be avoided as they can cause further increases. When you are trying to quickly lower your blood sugar, avoid foods that cause blood sugar spikes such as white bread, rice, pasta, and sweets. These types of foods can further raise your blood sugar.
If you have hyperglycemia, you may need to avoid foods that can raise your blood sugar. This can include foods that are high in sugar and refined carbs, such as white bread, bagels, and sweetened dessert items. Sugary beverages, processed snacks, and foods high in simple carbohydrates should be eliminated until blood sugar returns to a safer range.
Better Food Choices for Blood Sugar Management
When you need to eat while managing high blood sugar, focus on foods that won’t cause additional spikes. If you are hungry, opt for snacks or meals like high-fiber, non-starchy vegetables (such as leafy greens) or salads, nuts, legumes, avocados, lean proteins, and healthy oils like olive oil.
Non-starchy vegetables are one of the healthiest foods you can eat when living with diabetes. Not only will they fill you up, but they’re full of essential vitamins and minerals that help regulate your blood sugar. Non-starchy vegetables like broccoli, cucumbers and bell peppers are some of the best foods to lower blood sugar because of their low glycemic index.
The Role of Fiber in Blood Sugar Control
Fiber is one of the most important nutrients for managing blood sugar levels. Fiber slows your body’s digestion of carbohydrates and sugar absorption. That means it promotes more gradual increases in blood sugar levels.
Foods high in fiber (whole grains, beans, lentils, fruits and vegetables) will digest far slower and therefore lead to a gentle rise in blood sugar followed by a gentle fall, which is much better than a spike and crash. This slower digestion process helps prevent the dramatic blood sugar fluctuations that can be dangerous and uncomfortable.
All kinds of fiber are good for the body, but soluble fiber is best for improving blood sugar control. High fiber diets also help manage type 1 diabetes by helping the body regulate blood sugar. High fiber foods include fruit, vegetables, beans, and whole grains.
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.
Specific Foods That Support Blood Sugar Management
Leafy Green 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.
A 2016 study that included 42 Japanese adults demonstrated that consuming either 7 or 14 g of kale-containing foods with a high carb meal significantly decreased postmeal blood sugar levels compared with placebo. Research has shown that the flavonoid antioxidants found in kale, including quercetin and kaempferol, have potent blood sugar-lowering and insulin-sensitizing effects.
Nuts and Seeds
All nuts are high in protein and healthy fats. Healthy fats slow your digestive system and the rush of sugar from your gut to the bloodstream. Nuts such as almonds, cashews, and pistachios can be an effective way to help regulate blood sugar levels.
Seeds — chia, flax, pumpkin, sunflower, and sesame — are another great option, especially for people with nut allergies. These nutrient-dense foods provide protein, healthy fats, and fiber without causing blood sugar spikes.
Beans and Lentils
Beans and lentils are rich in magnesium, fiber, and protein. These nutrients may be able to help lower blood sugar. They’re particularly high in soluble fiber and resistant starch, which help slow digestion and may improve blood sugar response after meals.
A study of 12 women demonstrated that adding black beans or chickpeas to a rice meal significantly reduced postmeal blood sugar levels compared with eating rice alone. Many other studies have shown that eating beans and lentils can benefit blood sugar regulation and possibly help protect against the development of diabetes.
Berries
All fruits contain natural sugar, but berries have the lowest amount. They also contain more fiber than most other fruits, plus lots of healthy nutrients. Numerous studies link berry intake with improved blood sugar regulation. Berries contain fiber, vitamins, minerals, and antioxidants, and all of this makes them an excellent choice for people with blood sugar management issues.
Eat them with protein such as Greek yogurt, nuts, or cheese to help counteract the glucose, O’Meara advises. This combination helps slow the absorption of natural sugars and prevents blood sugar spikes.
Fatty Fish
Fatty fish like salmon and anchovies give you a significant serving of the omega-3 fatty acids DHA and EPA, which can help protect your heart against potential complications from diabetes. Seafood such as fish and shellfish provide protein, healthy fats, vitamins, minerals, and antioxidants that can help regulate blood sugar levels. Proteins are important for blood sugar control because it helps slow down digestions, which prevents post-meal blood sugar surges.
Eggs
A study of 42 adults with overweight or obesity and either prediabetes or type 2 diabetes showed that eating one large egg per day for 12 weeks led to a significant 4.4% reduction in fasting blood sugar and improvements in insulin sensitivity compared with an egg substitute. Eggs provide high-quality protein and healthy fats that support stable blood sugar levels.
Fermented Foods
Fermented foods such as kimchi and sauerkraut contain health-promoting compounds, including probiotics, minerals, and antioxidants. Research associates these compounds with improved blood sugar and insulin sensitivity. Research has found that regularly consuming probiotics may reduce both fasting blood sugar and A1C levels, especially in people with type 2 diabetes.
Understanding the Glycemic Index
Eating low-GI foods reduces blood sugar levels in people with diabetes. GI measures how the body absorbs or digests foods, which affects the rate at which blood sugar levels increase. GI is a measure of how fast a food can cause blood sugar to rise. A GI score is rated between 0 to 100.
Foods that have a high GI are often high in processed carbohydrates and sugars, are quickly digested and absorbed, and can cause a rapid rise in blood sugar. Foods with a low GI are broken down at a slower rate and cause a slower rise in blood sugar. Low GI foods are typically high in fiber, protein, and/or fat.
Foods with low (up to 55) to moderate (56-69) GI includes barley, yogurt, oats, burglar, beans, legumes, etc. In general, eating more low glycemic index foods may help reduce after-meal sugar spikes.
However, it’s important to note that glycemic index shouldn’t be followed in isolation. Portion size, cooked vs. raw, and content of other foods eaten at the same time have a significant impact. It is much more useful and effective to focus instead on meal balance (include vegetables, lean proteins, complex carbs with each meal), and portion size vs. glycemic index.
Balancing Your Plate for Optimal Blood Sugar Control
The key is balance — mixing sugars and carbohydrates with protein, fiber, and healthy fats. Choosing the right combination of foods can help you lower blood sugar naturally.
While Khan says there’s no scientific proof that a particular type of food can lower blood sugar, she stresses the importance of a balanced diet that includes adequate carbohydrates, unsaturated fat and lean protein. This can help keep your blood sugar levels in check.
It’s best to meet your daily carbohydrate requirements with complex carbohydrates, such as whole grains, lentils and legumes. The fiber in these foods slows digestion. This approach helps prevent the rapid blood sugar spikes that occur with refined carbohydrates.
Regulation of blood sugars is best achieved with consistent meals and snacks throughout the day made up of a balance of macronutrients (emphasis on high-fiber carbs, lean proteins, and unsaturated fats). Regular meal timing helps maintain stable blood sugar levels throughout the day.
Portion Control and Meal Timing
Portion control helps reduce the calories you eat, which helps you maintain a moderate weight. Controlling your weight promotes healthy blood sugar levels and reduces the risk of developing type 2 diabetes.
Reducing the portion of your meal can also help. The amount of food you eat has a great impact on your blood sugar. Using smaller plates and bowls, or splitting your meal in two can reduce your portions.
While carbohydrates are necessary for a balanced diet, eating too many leads to blood sugar spikes. Aim for a moderate intake, around 30-45 grams of carbohydrates per meal. However, individual needs vary based on factors like age, activity level, and overall health, so working with a registered dietitian can help determine your optimal carbohydrate intake.
Natural Remedies and Supplements
Apple Cider Vinegar
This trending type of vinegar is strong, sour, and made from fermented apple juice. It’s used in everything from sauces and salad dressings to skincare routines, and some research shows it might also assist in lowering blood sugar.
A 2021 review found that consuming one to two tablespoons of apple cider vinegar (make sure to dilute it with water first) with meals significantly decreased people’s fasting blood sugar. The fermented acetic acid helps to improve insulin sensitivity, decrease fasting blood sugar levels, and reduce blood sugar response when paired with meals that are rich in carbs.
Due to the high acidity of apple cider vinegar, it’s best to take it mixed with water to avoid damaging your teeth and esophagus. Start slowly, with about one teaspoon, and work your way up to one to two tablespoons.
Cinnamon and Turmeric
Cinnamon has been shown to help improve your blood sugar levels and insulin sensitivity while reducing A1C levels. Turmeric also lowers inflammation, helps regulate blood sugar levels, reduces your risk of developing heart disease, and benefits kidney health.
These spices can be easily incorporated into your daily diet. Cinnamon can be added to coffee, oatmeal, smoothies, or sprinkled on fruit. Turmeric works well in curries, soups, and can be made into golden milk or tea.
Chromium and Magnesium
High blood sugar levels are linked to deficiencies in minerals like chromium and magnesium, which regulate blood sugar. Chromium-rich foods include meats, fruit, vegetables, and nuts. Magnesium-rich foods include dark, leafy greens, squash and pumpkin seeds, tuna, whole grains, dark chocolate, bananas, and beans.
Important Note About Supplements
It might be tempting to try supplements, such as vitamin D, omega-3s and berberine, in hopes of lowering blood glucose. But despite a few promising studies, there isn’t yet proof that taking supplements will help prevent diabetes in someone with prediabetes.
Before taking any supplements, consult with your healthcare provider to ensure they won’t interact with your medications or cause adverse effects. Supplements should complement, not replace, a healthy diet and prescribed medications.
Stress Management and Blood Sugar
Stress can affect blood sugar levels. Hormones such as glucagon and cortisol are secreted during stress. Exercise, relaxation, and meditation significantly reduce stress and lower blood sugar levels. High blood sugar can occur from foods you eat, but it can also be caused by certain medications, infection, stress or pain.
Mind-Body Relaxation Techniques aim to establish harmony between the body and mind, thereby alleviating stress. This category encompasses practices like deep breathing, meditation, yoga, and progressive muscle relaxation. Each method harbors the potential to lower heart rate, decrease blood pressure, and slow respiration, encouraging an overall state of tranquility.
Incorporating stress-reduction techniques into your daily routine can have significant benefits for blood sugar management. Even just 10-15 minutes of deep breathing, meditation, or gentle yoga can help lower stress hormones and support better blood sugar control.
Monitoring Your Blood Sugar Levels
It’s important to monitor your blood sugar, and you should speak with your doctor to determine how often you should check it. By checking your blood sugar regularly, you can detect hyperglycemia early, and it can be managed appropriately.
Be sure to keep tabs on your blood sugars when they’re running above target. Ideally, checking hourly, or at least several times a day, is the goal. Whether you do a finger-stick or you check your CGM, knowing what’s going on with your glucose levels gives you valuable information and can help you adjust your foods intake and/or your medications.
Checking your blood sugar and then treating hyperglycemia early can help prevent any complications. Regular monitoring allows you to identify patterns, understand how different foods and activities affect your blood sugar, and make informed decisions about your diabetes management.
Keep a log of your blood sugar readings along with notes about what you ate, your activity level, stress levels, and any medications taken. This information can be invaluable when working with your healthcare team to optimize your treatment plan.
Working with Your Healthcare Team
You’ll need to work with your doctor to find the safest way for you to lower your blood glucose level. Cutting down on the amount of food you eat might also help. Work with your dietitian to make changes in your meal plan.
If exercise and changes in your diet don’t work, your doctor may change the amount of your medication or insulin or possibly the timing of when you take it. Your healthcare provider can help you develop a comprehensive treatment plan tailored to your individual needs.
If you have trouble keeping your blood sugar within your target range, schedule an appointment to see your health care provider. Your provider can help you make changes to better manage your diabetes.
Regular appointments with your healthcare team—including your primary care physician, endocrinologist, diabetes educator, and registered dietitian—are essential for successful diabetes management. These professionals can provide personalized guidance, adjust medications as needed, and help you navigate challenges.
Emergency Treatment for Severely High Blood Sugar
In critical situations where blood sugar levels exceed 250 mg/dl, immediate medical attention is necessary. Doctors may prescribe emergency medications or recommend intravenous insulin administration to rapidly lower blood sugar levels.
If you have signs and symptoms of diabetic ketoacidosis or hyperosmolar hyperglycemic state, you may be treated in the emergency room or admitted to the hospital. Emergency treatment can lower your blood sugar to a normal range.
Treatment usually includes: Fluid replacement. You’ll receive fluids — usually through a vein (intravenously) — until your body has the fluids it needs. This replaces fluids you’ve lost through urination. It also helps dilute the extra sugar in your blood.
Insulin therapy. Insulin reverses the processes that cause ketones to build up in your blood. Along with fluids and electrolytes, you’ll receive insulin therapy — usually through a vein. Emergency medical treatment is highly effective when administered promptly, which is why recognizing warning signs and seeking help immediately is so important.
Long-Term Complications of Uncontrolled Blood Sugar
Understanding the potential complications of chronic hyperglycemia underscores the importance of maintaining good blood sugar control. Long-term, or chronic hyperglycemia can lead to complications, including heart disease and stroke, kidney disease, nerve damage, eye problems, feet problems, skin conditions, hearing impairment, and even Alzheimer’s disease.
Over time, recurrent spikes in after-meal blood sugars can raise your HbA1c level. HbA1c is a measure of your average blood sugar over a three-month period. Having an elevated HbA1c has been shown to increase the risk of other health complications.
Research has shown that frequent high blood sugar levels after a meal can exacerbate the onset of kidney disease and accelerate the progression of retinopathy. These complications develop gradually but can have devastating effects on quality of life and overall health.
Your best bet is to practice good diabetes management and learn to detect hyperglycemia so you can treat it early—before it gets worse. Prevention and early intervention are always more effective than treating advanced complications.
Creating a Sustainable Blood Sugar Management Plan
One of the best ways to lower blood sugar is to take steps to prevent high blood sugar in the first place. If you’re choosing the right foods and exercising regularly, you’re likely to maintain good control of your blood sugar.
Developing sustainable habits is key to long-term success. Rather than making drastic changes all at once, focus on implementing one or two strategies at a time. Once these become routine, add additional healthy habits gradually.
It can be challenging to add new things to your diabetes care routine, but making small, daily changes – like getting more exercise or extra fiber – can help keep your blood sugar in check. Small, consistent changes are more sustainable than dramatic overhauls that are difficult to maintain.
Practical Tips for Daily Blood Sugar Management
Here are actionable strategies you can implement immediately to support healthy blood sugar levels:
- Keep water accessible: Place water bottles in multiple locations—your desk, car, bedside table—to encourage consistent hydration throughout the day.
- Plan your meals: Prepare balanced meals in advance to avoid making poor food choices when hungry or rushed. Include protein, healthy fats, and fiber with every meal.
- Schedule exercise: Treat physical activity like any other important appointment. Even a 15-minute walk after meals can make a significant difference.
- Manage stress proactively: Incorporate daily stress-reduction practices such as deep breathing, meditation, or yoga into your routine.
- Get adequate sleep: Poor sleep can affect blood sugar control and insulin sensitivity. Aim for 7-9 hours of quality sleep each night.
- Read food labels: Understanding the carbohydrate content and ingredients in packaged foods helps you make informed choices.
- Carry emergency supplies: Always have your blood glucose meter, testing supplies, and any necessary medications with you.
- Build a support system: Connect with others who understand diabetes management, whether through support groups, online communities, or friends and family.
- Keep a food and blood sugar journal: Tracking what you eat and how it affects your blood sugar helps identify patterns and problem foods.
- Stay educated: Continue learning about diabetes management through reputable sources, healthcare providers, and diabetes education programs.
Understanding Blood Sugar Patterns
It’s important to remember that blood sugar is supposed to rise after eating. It is a normal response to the digestion and metabolism of the food we eat, particularly carbohydrates, and it provides all our cells with energy.
A blood sugar spike occurs when your blood glucose level rises right after eating. This is actually a normal occurrence in all people after eating foods that contain carbohydrates. The difference for people with diabetes is that these normal responses are impaired, leading to higher and more prolonged blood sugar elevations.
Understanding your individual blood sugar patterns helps you anticipate and prevent problems. Some people experience higher blood sugar in the morning (dawn phenomenon), while others struggle more with post-meal spikes. Identifying your personal patterns allows you to target interventions more effectively.
The Importance of Consistency
Regular physical activity promotes insulin sensitivity and helps maintain healthy blood sugar levels. Engaging in a consistent exercise routine incorporating cardiovascular, strength training, and flexibility exercises can prove beneficial.
Consistency applies to all aspects of diabetes management—meal timing, exercise, medication, sleep schedule, and stress management. Your body responds best to predictable routines, which help stabilize blood sugar levels and make management easier.
However, life isn’t always predictable. Having strategies in place for handling disruptions—travel, illness, schedule changes, or special occasions—helps you maintain control even when circumstances aren’t ideal.
Special Considerations for Different Types of Diabetes
While many blood sugar management strategies apply to all types of diabetes, there are important distinctions. Lack of insulin can lead to a life-threatening condition called diabetic ketoacidosis. This is particularly relevant for people with Type 1 diabetes, who must take insulin to survive.
People with Type 2 diabetes may be able to manage their condition through lifestyle modifications alone, or may require oral medications, injectable medications, or insulin. The specific approach depends on individual circumstances, disease progression, and other health factors.
Gestational diabetes requires careful management during pregnancy to protect both mother and baby. Women with gestational diabetes need close monitoring and often require different treatment approaches than those with Type 1 or Type 2 diabetes.
Medication Considerations
Some medications like steroids can increase your blood sugar. Contact your team if you are started on this medication to see if you should begin monitoring your blood sugar and if medication to control blood sugar is indicated.
Many medications can affect blood sugar levels, including corticosteroids, certain blood pressure medications, some antidepressants, and others. Always inform your healthcare providers about all medications and supplements you’re taking, and ask about potential effects on blood sugar.
In some cases, your blood sugar may be high because of a missed dose of diabetes medication or insulin. If you miss a dose, contact your healthcare provider for guidance rather than trying to compensate on your own, as this could lead to dangerous blood sugar fluctuations.
The Role of Weight Management
A balanced diet that cuts carbs could help with weight loss — which itself is protective against diabetes — and quickly bring blood sugar back into a healthy range, according to findings published in JAMA Network Open.
For many people with Type 2 diabetes or prediabetes, losing even a modest amount of weight—5-10% of body weight—can significantly improve blood sugar control and may reduce or eliminate the need for medication. Weight loss improves insulin sensitivity and reduces the burden on the pancreas.
However, weight loss should be approached gradually and sustainably through healthy eating and regular physical activity rather than extreme diets or rapid weight loss methods, which are difficult to maintain and can be harmful.
Resources and Support
Managing blood sugar effectively requires knowledge, skills, and support. Diabetes education programs provide comprehensive training on blood sugar monitoring, medication management, nutrition, exercise, and problem-solving. Many insurance plans cover diabetes self-management education and support services.
Registered dietitians specializing in diabetes can provide personalized meal planning guidance. Certified diabetes educators offer practical advice and emotional support. Endocrinologists specialize in hormone-related conditions including diabetes and can manage complex cases.
Online resources from reputable organizations like the American Diabetes Association (https://www.diabetes.org), JDRF (https://www.jdrf.org), and the Centers for Disease Control and Prevention (https://www.cdc.gov/diabetes) provide evidence-based information and tools for diabetes management.
Support groups—both in-person and online—connect you with others facing similar challenges. Sharing experiences, strategies, and encouragement can make the journey less isolating and more manageable.
Looking Forward: Prevention and Long-Term Health
The vast majority with prediabetes — more than 80 percent — don’t know they have it, according to the CDC. The U.S. Preventive Services Task Force recommends people ages 35 to 70 who are overweight or obese get screened for prediabetes and diabetes. The American Diabetes Association (ADA) recommends screening for all people 45 and up and testing blood sugar earlier in those at higher risk for diabetes.
Early detection and intervention can prevent or delay the progression from prediabetes to Type 2 diabetes. Even for those already diagnosed with diabetes, excellent blood sugar control can prevent or slow the development of complications.
During an appointment, your health care provider may conduct an A1C test. This blood test shows your average blood sugar level for the past 2 to 3 months. It works by measuring the percentage of blood sugar attached to the oxygen-carrying protein in red blood cells, called hemoglobin. An A1C level of 7% or less means that your treatment plan is working and that your blood sugar was consistently within a healthy range. If your A1C level is higher than 7%, your blood sugar, on average, was above a healthy range.
Regular A1C testing provides valuable feedback about how well your blood sugar management strategies are working over time. This information helps you and your healthcare team make informed decisions about treatment adjustments.
Conclusion: Taking Control of Your Blood Sugar
Managing high blood sugar requires a multifaceted approach combining medication (when necessary), dietary strategies, physical activity, hydration, stress management, and regular monitoring. When asked if there are ways to lower blood sugar quickly, Khan says a combination of hydration, exercise and a decrease in sugars and carbs could help.
While there are no magic solutions for instantly lowering blood sugar, the strategies outlined in this article provide evidence-based methods for bringing elevated blood sugar down safely and effectively. The key is understanding which approaches work best for your individual situation and implementing them consistently.
Following a healthy dietary pattern is essential for optimal blood sugar management. Whether you have prediabetes or diabetes or want to reduce your risk of developing these conditions, including the foods listed above as part of a nutritious diet may help lower your blood sugar levels.
Remember that managing diabetes is a marathon, not a sprint. Focus on progress rather than perfection, celebrate small victories, and don’t be discouraged by setbacks. With the right tools, knowledge, support, and commitment, you can achieve and maintain healthy blood sugar levels and reduce your risk of complications.
Always work closely with your healthcare team, especially when making significant changes to your diet, exercise routine, or medication regimen. They can provide personalized guidance based on your unique health status, medications, and goals. By taking an active role in your diabetes management and implementing these evidence-based strategies, you can take control of your blood sugar and improve your overall health and quality of life.
