Wasting away due to disuse?

Explanation:
Atrophy is the wasting away of tissue due to disuse or reduced workload. When muscles aren’t used, their cells shrink and the tissue loses mass, leading to weakness over time. This differs from hypertrophy, where cells get bigger in response to increased use; dystrophy, which refers to degenerative or abnormal development of tissue; and necrosis, which is cell death from injury or lack of blood supply. In practical terms, disuse atrophy can happen with immobilization or prolonged inactivity, and restoring activity can help reverse it if the tissue hasn’t degenerated irreversibly.
