Managing Diabetes Safely in Patients Who Fast During Ramadan

Adjustments often include shifting dosing times to align with the pre-dawn and post-sunset meals, and in some cases reducing doses of medications associated with higher hypoglycemia risk, such as sulfonylureas or insulin. The specific adjustment approach depends on the medication class and the patient's individual risk profile. Healthcare professionals should review each patient's regimen individually before the fasting period begins.

Higher-risk patients typically include those with a history of severe or recurrent hypoglycemia, poorly controlled diabetes, advanced complications, or those on insulin or sulfonylurea therapy. Pregnant patients with diabetes and those with recent acute illness are also generally considered higher risk. These patients require more intensive pre-fasting counseling and closer monitoring throughout the fasting period.

Patients should be counseled to break their fast if they experience symptoms of significant hypoglycemia, severe hyperglycemia, dehydration, or acute illness, as continuing to fast under these conditions carries meaningful health risk. Clear, simple guidance on recognizing these warning signs should be part of pre-Ramadan counseling. Healthcare professionals should reinforce that safety takes priority over completing the fast.
