Atrophy is a medical term that refers to the wasting away, shrinking, or decrease in size of an organ or tissue in the body. This can occur as a result of a lack of use, injury, disease, or aging. Atrophy can affect muscles, organs, and even the brain, leading to functional impairment and weakness. Research in the area of atrophy focuses on understanding the underlying mechanisms, developing treatments, and exploring ways to prevent or slow down the process of tissue degeneration. This research is important for improving quality of life and managing various health conditions associated with atrophy.
