Diabetes is a silent enemy, often progressing without symptoms. Yet the feet can reveal early warnings that should never be ignored. Poorly controlled blood sugar damages tiny blood vessels and nerves, making feet the first to show changes.

Look for dry skin, deep cracks, or dark patches that resemble bruises but don’t fade—signs of circulation problems. Numbness or tingling, known as diabetic neuropathy, is another red flag, as injuries may go unnoticed and heal poorly. Swelling, redness, or warmth may signal infection, which diabetes makes harder to fight.

If you notice these symptoms, see a doctor immediately. Early diagnosis through a simple blood test, combined with blood sugar control, foot care, healthy diet, and exercise, can prevent severe complications.
