What is atrophy?

Atrophy refers to the decrease in size of an organ or tissue, which is often a result of the reduction in the size of its cells. This process can occur due to various factors, such as disuse, decreased blood supply, inadequate nutrition, or aging. When cells undergo atrophy, they may experience cell death and be resorbed by the body, leading to a noticeable reduction in overall tissue mass. Understanding atrophy is essential in fields like athletic training, as it can have implications for muscle health and recovery after injury or during periods of immobilization. Recognizing the signs of atrophy can inform strategies for rehabilitation and preventing further decline in tissue function.
