Sarcopenia is a progressive loss of muscle mass and strength that occurs during aging, often leading to an increased risk of maneuverability, frailty, and reduction. It is closely linked to malnutrition as it is insufficient absorption of proteins, calories and essential nutrients, which can promote muscle loss. Elderly people are particularly vulnerable due to factors such as reduced appetite, illness, and social isolation. Effective treatments for sarcopenia include nutritional support, particularly protein and vitamin D supplementation. Early intervention is essential to maintain muscle function, improve physical performance, and maintain independence for ageing people.
