Gangrene is a serious medical condition that occurs when body tissue dies due to a lack of blood flow, infection, or injury. It can affect any part of the body but is most commonly seen in the extremities like fingers, toes, and limbs. There are different types of gangrene, including dry gangrene, which is often caused by reduced blood supply, and wet gangrene, which is associated with bacterial infection. Treatment for gangrene typically involves removing the dead tissue to prevent the spread of infection. In severe cases, amputation may be necessary. Prompt medical attention is crucial, as untreated gangrene can lead to serious complications or even death.
