Understanding Gangrene: Causes, Symptoms, and When to See a Specialist

Gangrene: Causes, Symptoms, and Expert Treatment in Delhi

Gangrene is a serious medical condition that occurs when body tissues die due to a lack of blood flow or severe infection. While it can affect any part of the body, it most commonly appears in the arms, legs, fingers, and toes. Early diagnosis and prompt treatment are essential to save the affected area and prevent life-threatening complications.

In this blog, Dr. Tapish Sahu, a leading vascular and endovascular surgeon in Delhi, explains what gangrene is, how it develops, and why timely care from a vascular specialist is crucial.

What Is Gangrene?

Gangrene occurs when body tissue dies due to a loss of blood supply, infection, or trauma. It can develop suddenly or gradually and can be life-threatening if not treated early.

There are several types of gangrene:

• Dry Gangrene – Occurs when blood flow is reduced, often due to Peripheral Arterial Disease (PAD).

• Wet Gangrene – Caused by a bacterial infection, leading to swelling and tissue breakdown.

• Gas Gangrene – A rare but severe form caused by bacteria producing gas within tissues.

• Fournier’s Gangrene – A type that affects the genital and groin area, often rapidly progressive.

Causes and Risk Factors

Common causes of gangrene include:

• Blocked or narrowed arteries (Peripheral Arterial Disease)

• Diabetes mellitus

• Severe injuries or wounds

• Smoking

• Obesity

• Weakened immune system

People with diabetes and poor circulation are particularly at risk, especially in areas like the feet and toes.

Warning Signs & Symptoms

If you notice any of the following symptoms, seek immediate medical attention:

• Discoloration of the skin (black, blue, green, or red)

• Foul-smelling discharge or pus

• Numbness, coldness, or severe pain in the area

• Swelling or blisters filled with fluid

• Sudden onset of fever or fatigue (in case of infection)

Why Early Diagnosis Matters

Delaying treatment of gangrene can lead to the spread of infection, amputation, or even sepsis, a life-threatening condition. Early intervention by a vascular specialist can often save the affected limb and restore blood flow using advanced medical and surgical techniques.
