People with diabetes who wish to fast during Ramadan can receive help and information on a web site set up by Leicester's hospitals.
The aim is to provide tips on healthy eating, medications, lifestyle changes and how to manage diabetes, when people do not eat in the holy period.
The site is for those with diabetes, plus family members and health workers.
It is estimated there are 36,000 people with diabetes in Leicestershire, most of these people have Type-2 diabetes.
This form is more common amongst some ethnic minority groups. It is generally treated by diet, exercise and medications such as tablets and/or insulin.
Jane Grant, advanced nurse practitioner in diabetes at Leicester Royal Infirmary, said: "It is important for people with diabetes who will be fasting during Ramadan to plan in advance how to manage their diabetes and how to prevent themselves becoming ill unnecessarily.
"It is hoped that the information that can be accessed via the website will help people with diabetes and their families during Ramadan."
