Safety of Closed-loop Hybrid Insulin Administration During Ramadan Fasting in People Living With Type 1 Diabetes

Fasting in Ramadan is not recommended for people with type 1 diabetes. The main risk associated with fasting is dysglycemia (hypoglycemia, hyperglycemia, diabetic ketosis) and dehydration. Nevertheless, whether or not to practice Ramadan remains a personal choice and many people living with diabetes choose to perform this fast with or without their physician's approval. The purpose of this prospective observational study is to evaluate the safety and efficacy of an closed-loop hybrid insulin system on glycemic parameters and the level of hypoglycemia in patients with type 1 diabetes who wished to fast during Ramadan.
