People with type 2 diabetes at low risk of developing complications according to their current disease state are allowed to fast. This includes individuals with a shorter duration of type 2 diabetes (< 10 years), reasonably well-controlled glucose levels (HbA1c < 7.5 %), no major chronic diabetes complications, or no recent hospitalization for high or low glucose. However, if individuals choose to fast, they should be cautious and discontinue fasting if any problems arise. Likewise, those with uncontrolled type 2 diabetes, type 1 diabetes, and people with diabetes-related complications belonging to the high-risk category should refrain from fasting. People with diabetes planning to fast should meet their treating doctors and discuss the risks and safety of fasting. Your doctor is the best person to decide if it is safe for you to fast.
