sarcopeniu

Sarcopenia is a condition characterized by the progressive loss of skeletal muscle mass, strength, and function. It is a significant factor contributing to age-related decline, frailty, and increased risk of falls and fractures in older adults. The exact causes of sarcopenia are multifactorial, involving a complex interplay of physiological changes associated with aging, including hormonal alterations, decreased physical activity, nutritional deficiencies, and chronic diseases.

The diagnosis of sarcopenia typically involves assessing muscle mass, muscle strength (often measured by grip strength or lower extremity muscle strength), and physical performance (such as gait speed or the Short Physical Performance Battery). While aging is the primary risk factor, other conditions like cancer, diabetes, and heart disease can accelerate muscle loss.

The consequences of sarcopenia extend beyond reduced mobility. It can lead to decreased metabolism, impaired immune function, and a reduced ability to perform daily activities, significantly impacting an individual's quality of life and independence. Early identification and intervention are crucial.

Treatment and management strategies focus on increasing muscle mass and strength. Resistance exercise is widely recommended as the most effective intervention. Adequate protein intake is also essential to support muscle protein synthesis. Nutritional counseling to address potential deficiencies and management of underlying chronic conditions can also play a role in mitigating sarcopenia. Research into pharmacological interventions is ongoing, but lifestyle modifications remain the cornerstone of management.
