Everyone with diabetes planning to observe fasting should undergo a pre-Ramadan check-up. This check-up assesses each person’s glucose control, diabetic complications, and safety in observing fast. The treating doctor will investigate the glucose control, risk and severity of diabetes complications, risk of possible hypoglycemia during fasting, and the potential for worsening complications. The check-ups include tests of glucose control, kidney functions, liver function, assessment of eye issues, and cardiovascular disease. Based on these reports and clinical evaluation, the doctor will help classify your risk for fasting. People with low risk can observe fasting without much risk of worsening the disease. Those with high risk should preferably avoid fasting.
