New study seeks safer insulin dosing for ramadan fasters with diabetes
NCT ID NCT06826547
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 2 times
Summary
This study tests two methods for adjusting basal insulin in people with type 2 diabetes who fast during Ramadan. One method follows standard guidelines, while the other uses a personalized carbohydrate fasting test. The goal is to see which approach better controls blood sugar and reduces risks like hypoglycemia. About 60 adults aged 18–70 on insulin will participate.
