What to check on your feet every day if you have diabetes

One minute a day and a mirror. The signs worth looking for, why they can go unnoticed and which ones cannot wait.

A daily foot check is the most effective and cheapest measure there is for avoiding complications if you have diabetes. It takes a minute and needs nothing but light and, if you cannot see the sole, a mirror on the floor or someone’s help.

The underlying reason is uncomfortable but simple: diabetes can reduce sensation in the foot, and what you cannot feel does not warn you. A blister from new shoes, a small stone inside your sock or a nick while cutting a nail can go hours or days without hurting. Looking replaces feeling.

What to look for

You do not need to know how to diagnose: it is enough to notice that something has changed since yesterday.

  • Wounds, cuts, blisters or rubbed areas, however small.
  • Red areas, especially if the mark is still there a while after taking your shoe off.
  • Changes of colour: pallor, bruised or dark areas.
  • Areas that feel warm compared with the other foot.
  • New swelling in one foot and not the other.
  • Cracks in the heel or between the toes, and moisture or an unpleasant smell between them.
  • Hard skin and corns, which show where there is more pressure than there should be.
  • Nails that are thickened, changed in colour or digging in.
  • A feeling of tingling, burning, or of walking on cotton wool.

How to check them in a minute

  • In good light, at the end of the day: that is when marks from footwear show.
  • Sole, heel, between the toes and the top. If you cannot see the sole, use a mirror on the floor.
  • Dry carefully between the toes, and moisturise the rest of the foot while avoiding that area.
  • Also feel inside the shoe with your hand: a loose seam or a small stone is found there, not on the foot.

What not to do at home

  • Do not cut hard skin or corns with a blade, and do not use corn removers: on a foot with reduced sensation it is easy to do more damage than you feel.
  • Do not try to remove an ingrowing nail by poking down the side.
  • Do not use very hot water, hot water bottles or electric blankets: if sensation is altered you can burn yourself without realising. Check the temperature with your elbow or a thermometer.
  • Do not walk barefoot, not at home and not on the beach.

When to seek help the same day

If a wound that will not heal, pus, a spreading red area, heat, an unpleasant smell, a change of colour or pain that stops you standing appears, that does not wait for the next check-up. On a foot with diabetes or circulatory problems, time matters: what is dealt with early resolves far more easily.

And if none of that has happened, a regular check at the clinic is still worthwhile: much of the work consists of finding the problem before it gives any sign.
