Straight answers to the questions patients and families ask most about preventing diabetic foot ulcers — from daily foot checks to when to call the clinic.
Patients and families ask the same questions again and again about preventing diabetic foot ulcers. Here are direct answers.
How often should I check my feet?
Every day. Look at the tops, soles, heels, and between the toes. Use a mirror or ask a family member if you can't see the bottoms clearly. You're looking for redness, blisters, cuts, cracks, or any change in color.
What's the difference between a callus and a wound?
A callus is thickened skin from repeated pressure or friction. It's not a wound yet, but it's a warning — pressure is building in that spot. Never trim calluses yourself. Have your clinician assess them, because a callus can hide a wound underneath.
Can I soak my feet?
No. Soaking dries out the skin and can cause cracks that let bacteria in. Wash daily with lukewarm water and mild soap, dry thoroughly (especially between the toes), and apply moisturizer to the tops and soles — not between the toes.
What shoes should I wear?
Closed-toe shoes with a wide toe box and cushioned soles. Never go barefoot, even indoors. Check the inside of your shoes before putting them on — a small pebble you can't feel can cause a serious wound.
When should I call my clinician?
Call the same day if you see:
- Any open sore, blister, or crack
- Redness, warmth, or swelling
- Drainage or an unusual smell
- A change in skin color (dark, blue, or very pale)
- New numbness or burning
Does controlling blood sugar really protect my feet?
Yes. High glucose damages the small nerves and vessels in your feet over time. That's why an HbA1c at or below 7% matters — it lowers the risk of the injury you can't feel becoming a wound that won't heal.
