“Every amputation I perform that was preceded by years of uncontrolled diabetes is a moment I wish the patient had received this information a decade earlier.”
By Dr. Rahul Agarwal | Consultant Vascular & Endovascular Surgeon, CARE Hospitals, Banjara Hills, Hyderabad
The statistic is stark: diabetics are 10 to 15 times more likely to undergo lower limb amputation than people without diabetes. In India, where diabetes affects over 100 million people and control rates remain low, this translates into tens of thousands of preventable amputations every year.
As a vascular and endovascular surgeon who performs both amputations and limb salvage procedures, I want to be clear: the overwhelming majority of diabetic amputations are preventable.
🚶 The Preventable Pathway: How Amputation Develops
Stage 1: Poor Glucose Control → Neuropathy
Chronically elevated blood sugar damages the small blood vessels supplying peripheral nerves. Over years, sensation in the feet diminishes. Break the chain: Achieve HbA1c below 7%.
Stage 2: Neuropathy + PAD → Ulceration
Neuropathy removes the pain warning. PAD reduces blood supply to the foot. Together, minor trauma goes unnoticed and unhealed. Break the chain: Annual foot examination, proper footwear, daily self-examination.
Stage 3: Ulceration → Infection
An open wound on an ischaemic foot is an infection waiting to happen. Diabetic immune dysfunction means the body cannot fight bacteria effectively. Break the chain: Seek medical attention for any foot wound within 24 hours.
Stage 4: Infected Ischaemic Foot → Gangrene
When infection is superimposed on inadequate blood supply, tissue dies. Break the chain: Emergency vascular assessment and revascularisation can often allow minor amputation rather than major amputation.
🛡️ The Seven Pillars of Amputation Prevention
- 1. Glucose control: HbA1c below 7% is the foundation
- 2. Annual foot examination: Including monofilament testing, pulse assessment, and ABI
- 3. Proper footwear: Never walk barefoot
- 4. Daily foot inspection: Inspect the entire foot — including between toes — every single day
- 5. Immediate attention to any wound: Any break in skin warrants same-day or next-day medical review
- 6. Smoking cessation: Single most reversible risk factor for diabetic foot outcomes
- 7. Early vascular referral: Any diabetic with absent foot pulses needs urgent assessment
❓ Frequently Asked Questions
If I have diabetes, how can I tell if my circulation is poor?
Signs include cold feet, absent or weak pulse at the ankle, shiny and hairless skin, or wounds that won’t heal. An ABI test at your annual diabetes review detects silent PAD.
My doctor says I might need an amputation. Is there an alternative?
In many cases, yes. Vascular assessment including angioplasty or bypass can restore blood supply and allow healing. A second opinion from a vascular surgeon with limb salvage experience is always worthwhile.
🔑 Key Insights: Diabetic amputation follows a predictable, preventable chain: poor glucose control → neuropathy → ulceration → infection → gangrene → amputation. Every stage is an intervention point. The seven pillars are evidence-based and available to every patient.
