Age-related dynamics of body homeostasis individual indicators in patients with risk of developing frailty and without frailty was studied in the research. Clinical indicators mostly associated with age were determined: muscle strength, glomerular filtration rate, total protein, potassium, hemoglobin, alanine aminotransferase activity, and blood plasma glucose. The contribution of reduced overall renal function, as well as anabolic activity of the liver in the development of age-related changes and frailty was studie
