Effects of anti-diabetic drugs on sarcopenia: Best treatment options for elderly patients with type 2 diabetes mellitus and sarcopenia

Human life expectancy increases as society becomes more developed.This increased life expectancy poses challenges associated with the rapid aging of the population.Sarcopenia,an age-related disease,has become a worldwide health issue.Patients with sarcopenia experience decreases in muscle mass and function,becoming frail and eventually bedridden.Type 2 diabetes mellitus(T2DM)is also a major health issue;the incidence of T2DM increases with aging.T2DM is associated with reduced muscle strength and poor muscle quality and may contribute to acceleration of the aging process,augmenting age-related sarcopenia.Recent studies indicate that elderly patients with diabetes are at an increased risk for sarcopenia.Therefore,these older diabetic patients with sarcopenia need specific anti-diabetic therapies targeting not only glycemic control but also sarcopenia,with the goal of preventing sarcopenia in presarcopenic patients.Presently,various types of hypoglycemic drugs are available,but which hypoglycemic drugs are better suited for geriatric T2DM patients with sarcopenia remains undetermined.In this review,we discuss the association between diabetes and sarcopenia in geriatric patients,and how anti-diabetic drugs may influence sarcopenia outcomes.This review will guide clinical workers in the selection of drugs best suited for this patient population.
