The International Diabetes Federation (IDF) and the Diabetes and Ramadan (DAR) International Alliance have therefore come together to deliver comprehensive guidance on this subject. The IDF-DAR Practical Guidelines provide healthcare professionals (HCPs) with relevant background information and practical recommendations to enable them to help people with diabetes participate in fasting during Ramadan while minimising the risk of complications.
