Shrinkage of tissue by a decrease in either cell number or cell size is called atrophy (at′rō-fē). Atrophy may result from normal aging (senile atrophy) or from failure to use an organ or tissue (disuse atrophy).

Why does atrophy happen?

Lack of physical activity due to an injury or illness, poor nutrition, genetics, and certain medical conditions can all contribute to muscle atrophy. Muscle atrophy can occur after long periods of inactivity. If a muscle does not get any use, the body will eventually break it down to conserve energy.

What causes cell atrophy?
