Sarcopenia is a type of muscle loss (muscle atrophy) that occurs with aging and/or immobility. It is characterized by the degenerative loss of skeletal muscle mass, quality, and strength.
Causes
A common cause of sarcopenia is decreased physical activity throughout the day. However, although less frequent, some people with active lifestyles may also be diagnosed with sarcopenia. This suggests that there could be other reasons for the development of the disease.
