What is gangrene?

Gangrene refers specifically to the necrosis or death of tissue, which typically occurs due to a lack of blood supply or an infection. It is a serious medical condition that can affect any part of the body, though it is most commonly seen in the extremities (like fingers and toes) and can be life-threatening if not treated promptly.

The process of gangrene usually surfaces when blood flow is reduced due to various reasons, such as injury, diabetes, or infection, leading the affected tissue to become necrotic. The lack of oxygen and nutrients results in the tissue dying and, if not managed effectively, this can lead to severe complications, including the need for amputation or systemic issues if the necrosis becomes widespread.

Understanding gangrene is critical in the medical field, as recognizing the early signs can significantly influence treatment outcomes, preventing severe ramifications associated with tissue death.
