Fasting with diabetes requires strict medical supervision to manage risks like hypoglycemia, hyperglycemia, and dehydration.
Key guidelines include consulting a doctor to adjust medications, eating a balanced, high-fiber Suhoor, staying hydrated, and monitoring blood glucose levels frequently. Fasting should be broken immediately if blood sugar drops below 70 mg/dL (3.9 mmol/L) or rises above 300 mg/dL (16.7 mmol/L).
Key Risks
Hypoglycemia (Low Blood Sugar): High risk, especially with insulin or sulfonylureas, if medication is not adjusted.
Hyperglycemia (High Blood Sugar): Occurs from overeating at Iftar or reduced medication.
Dehydration: Due to long fasting hours, increasing thrombosis risk.
Diabetic Ketoacidosis (DKA): A dangerous, emergency condition, particularly for Type 1 diabetics.
Guidelines and Safety Tips
Consult a Professional: Always speak with a healthcare provider 6–8 weeks before fasting to adjust medication dosages and timing.
Monitor Frequently: Check blood sugar at least 3-4 times daily (before/after Suhoor, mid-day, before Iftar). Checking glucose does not break the fast.
Manage Meals: Never skip Suhoor (pre-dawn meal). Consume complex carbohydrates, fiber, and protein for sustained energy.
Hydration: Drink ample water between Iftar and Suhoor to avoid severe dehydration.
Break the Fast: Immediately end the fast if feeling dizzy, weak, confused, or if glucose levels are <70 mg/dL or >300 mg/dL.
