Fasting poses significant risks to people with diabetes because the combination of long periods without food together with diabetes medications can result in very low blood sugar (hypoglycaemia), or in very high blood sugar (hyperglycaemia) if insulin or medication doses are reduced excessively to try to prevent hypos. In addition, restricting fluids during fasting can cause dehydration.

If you have diabetes treated with insulin, injectable treatment or tablets, contact the Diabetes Specialist Nurses for advice about how to manage your diabetes during Ramadan:
