Diabetes is a common and serious disease. However, the past 50 years have seen a growing ageing population with an increasing prevalence of type 2 diabetes mellitus (DM2). Now, nearly half of all individuals with diabetes mellitus are older adults (aged ≥65 years). Elderly people with diabetes is a heterogeneous group, in many cases the condition of diabetes is accompanied by other chronic diseases, but also by the ability of the elderly themselves to control their blood glucose. The therapeutic treatment of elderly diabetic patients must be done with special attention and a lot of thought. Special importance should be given to exercise with aerobic exercise or alternatively the application of a program of progressive increase in muscle intensity (3-5 times a week), as well as training in proper nutrition with particular emphasis on the Mediterranean diet, which seems to increase survival in adults.
