Gangrene is typically caused by a lack of blood flow to a certain part of the body, leading to tissue death. This lack of blood flow can be the result of an injury, infections, diabetes, atherosclerosis, or other medical conditions that affect the blood vessels. In some cases, gangrene can also be caused by bacterial infections that invade and destroy the tissue. It is important to seek medical attention immediately if you suspect you have gangrene, as it can lead to serious complications and require prompt treatment.
