Diabetic Foot Sore: Causes, Risks, and What You Can Do

When you have diabetes, a small diabetic foot sore, a break in the skin on the foot that doesn’t heal easily due to nerve damage and poor circulation. Also known as diabetic foot ulcer, it’s not just a cut—it’s a warning sign that your body’s healing system is struggling. Many people don’t feel these sores at first because high blood sugar damages the nerves in your feet, a condition called diabetic neuropathy, nerve damage caused by long-term high blood sugar that reduces sensation in the feet. You might walk on it for days without knowing, and by the time you see it, it’s already infected.

What makes these sores dangerous isn’t just the wound itself—it’s what’s happening underneath. Poor blood flow, or peripheral artery disease, a condition where arteries narrow and reduce blood flow to the limbs, especially the legs and feet. means oxygen and healing nutrients can’t reach the sore. At the same time, high sugar levels weaken your immune system, making it harder to fight off bacteria. This combo turns a tiny blister into a deep ulcer, sometimes leading to bone infection or even amputation. The good news? Most of these sores are preventable with daily foot checks, proper shoes, and steady blood sugar control.

You don’t need to wait for a crisis. Check your feet every day—look between the toes, under the balls of your feet, and around the heels. Use a mirror if you can’t see the bottom. Wash and dry them gently. Never go barefoot, even inside. If you notice redness, swelling, drainage, or a sore that doesn’t improve in a few days, see a doctor right away. Your blood sugar numbers matter more than you think. Keeping them steady isn’t just about energy or mood—it’s about keeping your feet alive.
