Diabetic Foot Care: Why Your Feet Need Extra Attention

If you have diabetes, looking after your feet is not optional — it prevents serious problems. A clear, practical guide to daily foot care, warning signs, and protecting your feet for life.

If you or a family member has diabetes, here is something that does not get talked about enough but truly matters: foot care. Diabetes can quietly damage the nerves and blood flow in the feet, so a small cut, blister, or crack can turn into a serious wound — sometimes without you even feeling it. The good news is that simple daily care prevents the vast majority of these problems. This is a clear, practical guide to protecting your feet when you have diabetes.

Why Diabetes Affects the Feet

Over time, high blood sugar can damage the nerves (so you feel pain, heat, or injury less — a small stone or blister may go unnoticed) and narrow the blood vessels (so wounds heal more slowly). Together, this means a minor injury can become infected and worsen before it is noticed. Because the feet are far away and easy to overlook, they are especially vulnerable — which is exactly why they need deliberate attention.

Daily Foot Care Routine

  • Check your feet every day — tops, soles, and between the toes — for cuts, blisters, redness, swelling, or colour changes (use a mirror or ask for help if needed)
  • Wash daily in lukewarm (not hot) water, dry gently, especially between the toes
  • Moisturise dry skin — but not between the toes (that stays damp and can cause fungal infection)
  • Cut toenails straight across, carefully, to avoid ingrown nails
  • Never walk barefoot — even at home; a small unnoticed injury is the common start of trouble
The daily check is the whole secret Because nerve damage can dull sensation, you might not *feel* a developing problem — so you have to *look*. A 30-second daily foot check catches issues while they are tiny and easily fixed. This one habit prevents most serious diabetic foot problems.

Choosing Footwear

  • Wear well-fitting, comfortable shoes that don't rub or pinch
  • Check inside shoes before wearing for stones, grit, or rough seams
  • Break in new shoes gradually
  • Wear clean, dry socks; avoid tight elastic that restricts circulation

Warning Signs — Don't Wait

See a doctor promptly if you notice
  • A cut, blister, or wound that is not healing
  • Redness, warmth, swelling, or pus (signs of infection)
  • Skin turning dark, blue, or black, or a cold, pale foot
  • Numbness, tingling, burning, or new pain in the feet
  • An ingrown toenail, corn, or callus you're tempted to cut yourself — let a professional do it

A foot wound in someone with diabetes is not a "wait and see" situation — it needs prompt medical attention, because early treatment prevents serious complications.

The Bigger Picture

Good foot care works alongside managing your diabetes well — keeping blood sugar controlled is what protects your nerves and circulation in the first place, and not smoking helps blood flow. Ask your doctor to examine your feet at your regular check-ups too, even when they feel fine. (See our guides on understanding diabetes and living well with a chronic condition.)

When to See a Doctor

See a doctor promptly for any foot wound, sign of infection, colour change, or new numbness or pain — do not delay, as diabetic foot problems can escalate quickly. Have your feet checked at routine diabetes reviews, and see a doctor (or podiatrist) for corns, calluses, or nail problems rather than cutting them yourself. An online consultation is useful to review your diabetes care and decide how urgently a foot problem needs to be seen in person — though an infected or non-healing wound should be examined promptly. Looking after your feet is one of the most important, and most overlooked, parts of living well with diabetes.
