Gangrene is a condition which occurs when some tissues in a particular part of the body perish due to lack of oxygen-rich blood. Often this can happen in the hands or the feet, but it can arise in any part of the body. It is important to understand that gangrene is a serious condition and needs to be addressed right away, as it can lead to amputation or even be fatal.

Primarily there are two types of gangrene, i.e., wet and dry gangrene.

• Dry gangrene Also known as mummification, this kind of decay progresses at a slower pace and is mostly a result of chronic disorders such as diabetes. In such cases, the skin turns dry, dark and wrinkled. Apart from hyperglycemia, it can be the consequence of Raynaud’s disease, severe burns, frostbite, etc.
• Wet gangrene In this type of gangrene, the skin gets inflamed and creates blister which may contain pus. Typically wet gangrene can develop due to injuries, embolism, and a fragile immune system.

Apart from wet and dry gangrene, there are two rare types of gangrene, i.e., gas and Fournier’s.

• Gas gangrene This form of infection rarely occurs, but it can be life-threatening. It is when the infection takes place in inside the body, mostly because of trauma. Bacteria known as clostridia is responsible for gas gangrene as it releases poisons which radiates through the entire body along with gas trapped within the tissues. As the stages of gas gangrene progress, the skin begins to turn paler and when pressed makes a snapping noise due to the stuck gas.
• Fournier’s gangrene This kind of gangrene attacks the genital area and is relatively rare. But it is more prevalent in men. However, both women and children can contract it. Fournier’s gangrene is caused due to hysterectomies, bladder infections, urinary tract disease and abscesses.

Ten early signs of gangrene

• Glossy appearance of the skin
• Shedding of the skin with a discernable line forming between the affected and healthy area
• Wound that does not appear to better
• Discoloration of the infected area which turns dry and dark
• The affected part will be cold
• Loss of sensation
• Nausea
• Faster pulse rate
• Fever
• Bleeding or pus-producing blisters

Depending on the type of case, these early signs of gangrene may vary from person to person. If you notice any of the early signs of gangrene mentioned above, immediately notify the doctor. Without medical intervention, gangrene can spread to the blood and result in sepsis.
