Fasting is considered a requirement for all Muslim adults, regardless of your gender, occupation, ethnicity… However, there are exemptions for people with serious medical conditions, which in some cases includes type 2 diabetes.  

A vast majority of people with diabetes do not consider themselves to be part of that exemption and will fast anyway. While there are certain cases of diabetes which can tolerate, under specific instructions, safe fasting, there are other cases of diabetes where it may result in serious health complications. That’s why it’s advisable to speak with your doctor about whether or not you should fast.

The International Diabetes Federation published a report with a risk classification for people with diabetes mellitus who want to fast. Take a look at the table below and see where you fall.
