Early Signs of Diabetic Foot Problems
Numbness, callouses and minor cuts can escalate quickly in diabetes. Here's a daily checklist that can save your limb.
India has the second-largest diabetic population in the world. Up to 25% of diabetics will develop a foot ulcer in their lifetime, and a small percentage of these progress to amputation. The good news: nearly every diabetic foot complication is preventable with early recognition and timely vascular review.
Daily warning signs
- Numbness, tingling or 'pins and needles' in the toes or sole.
- Reduced sensation to heat, cold or pain — you may not feel a small cut.
- Thickened callouses, particularly on the ball of the foot.
- Cracks between the toes or around the heel that refuse to heal.
- A persistent reddish or dark patch, blister or unexplained swelling.
- Foul-smelling discharge from a cut or under a nail.
Why diabetic feet need a vascular review
Two problems converge in diabetes: nerve damage (neuropathy) hides pain, while small-vessel disease starves tissue of oxygen. A trivial injury can become a deep ulcer within days. A vascular surgeon assesses circulation using duplex ultrasound and ABI, then revascularises if blood flow is inadequate.
Daily prevention checklist
- Inspect both feet every night — use a mirror for the soles.
- Wash with lukewarm water and dry thoroughly between the toes.
- Apply moisturiser, but never between the toes.
- Wear properly fitted, closed footwear — even indoors.
- Never walk barefoot, even at home or in temples.
- Trim nails straight across; avoid sharp tools and home pedicures.
When to seek urgent care
Any redness, swelling, blackening, sudden warmth or non-healing wound — even one that seems small — warrants same-day evaluation. Modern limb-salvage protocols save more than 90% of feet when the patient presents within 72 hours.
