sarcopenia

A condition characterized by loss of muscle mass, strength, and function in older adults. Signs and symptoms include weakness, fatigue, loss of energy, balance problems, and trouble walking and standing. Muscle loss or weakness can lead to falls, broken bones, and other serious injuries and can affect a person’s ability to care for oneself. Older age, getting little or no exercise, and poor nutrition may increase the risk of sarcopenia. Sarcopenia may also occur in people with cancer.
