Understanding Cystic Fibrosis and Diabetes

Cystic fibrosis is an autosomal recessive disorder caused by mutations in the CFTR gene, which encodes a chloride channel expressed in epitelial tissues. Te resulting defect in ion transport leads to thick, viscous sekretions in the lungs, pancorps, liver, tencines, and reproductive tract. Over 180,000 individuals worldwide affected.

CFRD is a diment form of diabetes that shares appures of both type 1 and type 2 diabetes but is not identical to either. Thee primary defect is a progressive reduction in insulin sekretion due to pankreatic fibrosis and destruction of islet cells.

Identififying and Managing Risk Factors

Blood Glucose Monitoring and Kétane Testing

Nutritional Guidance and Dietary Planning

Nutrition in CF is complex because patients need high-calorie, high-fat diets to maintain body weight and lung function. For patients with CFRD, dietary education must balance caloric needs with glucose control. Carbohydrate counting is the most effective method for matching prandial insulin doses, but the focus should be on consistent carbohydrate intake rather than severe restriction, which is not appropriate in this population. A dietitian with CF expertise should help patients and families identify carbohydrate-containing foods, teach label reading, and develop meal plans that incorporate enough fiber, protein, and healthy fats to slow glucose absorption. Fat malabsorption due to pancreatic insufficiency further complicates glucose excursions; enzyme replacement therapy should be optimized to improve nutrient digestion and reduce unpredictable glycemic swings.

Patient and Caregiver Education

Education is them foundation of DKA prevention.

  • Never stop insulin completely - basal insulin bale continued, often at higer doses (např., 110-120% of usual) during illness.

  • If ketones are present and glukose is high, administrar an extra dose of rapid- acting insulin (e.g., 10-20% of total daily dose as correction) and increase fluid intake.
