🩸 Gangrene: Types, Causes, Symptoms, and Treatment Introduction Gangrene is a serious medical condition that occurs when body tissues die due to a loss of blood supply , infection , or trauma . It most commonly affects the extremities — such as the toes, fingers, feet, or hands — but can also occur in internal organs. In clinical practice, gangrene is considered a medical emergency because it can spread rapidly and may lead to sepsis (blood infection) or amputation if not treated promptly. Early recognition and proper management are critical to saving both tissue and life. Definition Gangrene is defined as the death of body tissue resulting from ischemia (lack of blood flow) , infection , or injury . When cells are deprived of oxygen and nutrients for too long, they die, and the surrounding area begins to decay. Causes of Gangrene Gangrene usually develops due to one or more of the following causes: Reduced Blood Supply (Ischemia): Caused by peripheral arterial dise...

Gangrene: Causes, Symptoms, Types, Treatment, and Physiotherapy Management Introduction Gangrene is a serious and potentially life-threatening condition that occurs when a significant mass of body tissue dies ( necrosis ). It results from a critical lack of blood supply, often caused by infection, injury, or chronic disease that impairs circulation. Without immediate treatment, gangrene can spread rapidly, causing systemic infection ( sepsis ), amputation, or death. Gangrene most commonly affects the extremities like the toes, fingers, hands, and feet, but it can also occur in internal organs and muscles. Symptoms of Gangrene Symptoms of gangrene depend on the type and location but commonly include Skin discoloration (black, blue, purple, red, or bronze) Numbness or severe pain in the affected area Swelling and blisters that may emit a foul-smelling discharge A sudden drop in temperature or coolness of the affected skin Tissue that feels cold, hard, or dry Fever...
