Dry gangrene is a type of tissue death that occurs when blood flow to a specific area is severely reduced or cut off. This condition often affects the extremities, such as fingers and toes, and is commonly caused by peripheral artery disease, diabetes, or other circulatory issues. The affected tissue becomes dry, shriveled, and may turn black as it dies. Unlike wet gangrene, which is associated with infection and swelling, dry gangrene typically develops slowly and is less likely to spread. Treatment often involves improving blood flow, managing underlying conditions, and in some cases, surgical removal of the dead tissue.
