"atrophy"의 정의 및 의미

What is "atrophy"?

Atrophy is the gradual loss of muscle or tissue mass, often due to a lack of physical activity, aging, disease, or injury. When muscles are not used regularly, they shrink and weaken over time. This condition can affect any part of the body and may result from prolonged bed rest, immobilization, such as wearing a cast, or neurological conditions like multiple sclerosis or stroke. Symptoms of atrophy include reduced muscle size, weakness, and decreased strength. Treatment typically involves physical therapy, exercise, and addressing the underlying cause to help rebuild muscle mass and improve function. In some cases, nutritional support and medical treatments may also be necessary.
