Gas gangrene is a severe bacterial infection that occurs when certain bacteria, often from the Clostridium species, enter the body through wounds. These bacteria thrive in low-oxygen environments, producing gas and toxins that damage tissues. Symptoms include swelling, severe pain, and a foul-smelling discharge. If left untreated, gas gangrene can lead to serious complications, including tissue death and systemic infection. Treatment typically involves surgical removal of affected tissue, antibiotics, and sometimes hyperbaric oxygen therapy to help combat the infection and promote healing. Early intervention is crucial for a better outcome.
