Muscle atrophy

is the loss of muscle mass due to a decrease in muscle size and strength. This can occur as a result of various factors including lack of physical activity, injury, illness, aging, or nerve damage. When muscles are not used or stimulated, they can shrink and weaken over time. Muscle atrophy can lead to decreased mobility, balance problems, and increased risk of injury. Treatment for muscle atrophy often involves physical therapy, exercise, and proper nutrition to help rebuild and strengthen the muscles.
