Diabetes mellitus and Ramadan in elderly patients.

Worldwide, the proportion of people above 60 years old represents 15% of the whole population. Diabetes mellitus is more frequent in this age group, and is associated with increased risk of morbidities and premature mortality. Aged Muslim people with diabetes insist on fasting during Ramadan, for many reasons. Elderly people, especially frail patients, who fast are at increased risk for many complications such as hypoglycaemia, hyperglycaemia and metabolic decompensation including hyperosmolar coma, diabetic ketoacidosis, dehydration and thrombosis. Therefore it is important to assess functional capacity, cognition, mental health and comorbidities in elderly people with diabetes in order to evaluate the risk of fasting, individualize the therapy, and adapt care to their needs.
