Signs of Diabetic Foot and Leg Ulcers: How to Spot Them & Treat Them

Living with diabetes means paying closer attention to your feet than most people need to. Recognizing the first signs of trouble — before they become complications — is one of the most empowering things you can do for your long-term mobility.

What Are Diabetic Foot and Leg Ulcers?

These are open sores or wounds that commonly develop on the feet, ankles, or lower legs, typically caused by a combination of poor circulation, nerve damage (neuropathy), and a weakened immune response. Because neuropathy reduces sensation, injuries often go unnoticed until they've already worsened — while poor circulation slows healing and raises infection risk.

Signs to Watch For

• Changes in skin appearance: discoloration ranging from reddish or bluish tints to darkened spots, or changes in texture.
• Physical symptoms: blisters or sores that don't heal in a reasonable timeframe, swelling, warmth, or tenderness.
• Extended healing periods: wounds that seem to take unusually long to close.
• Open sores or discharge: any clear, cloudy, or bloody discharge, especially with an odor, warrants prompt attention.

Treatment and Prevention

• Clean and dress wounds properly using sterile saline and moisture-balancing dressings, avoiding harsh antiseptics like hydrogen peroxide.
• Wear proper footwear with extra depth, soft interiors, and no irritating internal seams — even indoors.
• Exercise feet and ankles with gentle daily movement to stimulate circulation.
• Monitor blood sugar daily since elevated glucose slows healing and raises infection risk.
• Schedule regular podiatric evaluations so a professional can catch developing issues early.
• Commit to a diabetes-friendly diet rich in vegetables, lean protein, and hydration to support tissue repair.

Maintaining excellent foot health with diabetes is an ongoing practice, not a one-time fix — and timely intervention makes the biggest difference in outcomes.
