The paper presents studies that prove the possibility of preventing the transition of prediabetes to diabetes. Various methods of preventing type 2 diabetes mellitus, including lifestyle changes, medications, and metabolic surgery in patients with prediabetes, are being considered. Particular attention is paid to the effectiveness and possibility of using these methods of prevention in the elderly in general.

[Problems of choosing hypoglycemic therapy in elderly patients (literature review).]

Type 2 diabetes mellitus is one of the most common non-infectious diseases in the world. Among people with type 2 diabetes, patients of the older age group predominate: 60,5% of all patients are over 65 years old, and the peak prevalence is at the age of 65-69 years. The treatment of this pathology in elderly patients has certain features, which is associated with a high level of polymorbidity in these patients. Therapy for type 2 diabetes should be aimed not only at compensating the level of glycemia, but also at treating and preventing complications of diabetes, and improving the quality of life of patients. The choice of hypoglycemic therapy should take into account the effect of drugs on the cardiovascular system and kidney function, as well as the risk of hypoglycemia, which is more common in older people and affects the cognitive function of such patients. This review discusses the possibilities of using various groups of antidiabetic drugs in elderly and old patients.
