What is Gangrene?

Gangrene occurs when tissues in the body die due to inadequate blood flow or severe infection. It most commonly affects the extremities like toes, fingers, and limbs but can also involve internal organs and muscles.

  • Appearance: Gas bubbles under skin, severe pain, foul odor, blackened tissue.

  • Urgency: Medical emergency, requires immediate surgical and antibiotic therapy.

4. Internal Gangrene
