Diabetic Foot Gangrene: Causes, Symptoms, and Advanced Treatment at Asian Vascular Hospitals

Diabetic Foot Gangrene is a serious and potentially life-threatening complication of diabetes, where poor blood circulation and nerve damage lead to tissue death. Without timely treatment, Diabetic Foot Gangrene can spread quickly, resulting in severe infections, amputation, or other critical complications. Understanding its causes, symptoms, and treatment options is crucial for protecting your health.

What is Diabetic Foot Gangrene?

Diabetic Foot Gangrene occurs when tissue in the foot loses its blood supply due to poor circulation, often worsened by nerve damage from diabetes. This lack of oxygen and nutrients causes the tissue to die, turning black, brown, or green, and becoming prone to infections.

Causes of Diabetic Foot Gangrene

• Peripheral Artery Disease (PAD) – Narrowed blood vessels reduce circulation
• Uncontrolled Diabetes – High blood sugar damages nerves and blood vessels
• Infections – Minor wounds that worsen due to poor healing
• Foot Injuries – Cuts, blisters, or ulcers left untreated
• Smoking & Alcohol – Further reduce blood flow and healing ability

Symptoms to Watch For

If you have diabetes, early detection of Diabetic Foot Gangrene can save your limb:

• Black, dark brown, or green skin on the foot or toes
• Persistent foul smell
• Severe foot pain or numbness
• Swelling, redness, or pus discharge
• Fever and general weakness in advanced cases

Diagnosis

At Asian Vascular Hospitals, our specialists use:

• Physical Examination of the foot
• Doppler Ultrasound to check blood flow
• MRI/CT Scans for infection spread
• Blood Tests for infection and sugar control
