Gangrene is dead body tissue which is common in the fingers and toes but can occur throughout the body. There is dry and moist gangrene. Generally gangrene can be caused by diabetes, smoking, injury, frostbite, severe burns, excessive alcohol consumption and thrombosis. Symptoms of external gangrene may include discolouration, loss of feeling to the areas and a smelly discharge. Symptoms of internal gangrene can include severe pain, septic shock, fever and feeling sick. Gangrene can be treated with antibiotics, pain relief medication, removal of the dead tissue, hyperbaric oxygen therapy, anticoagulants and by keeping the wound sterile and clean.
