Diabetic Foot Ulcer Prevention: Neuropathy, Poor Healing and Daily Foot Care

Diabetes can damage nerves, circulation, immunity, and wound healing. These changes make small foot injuries easy to miss and harder to heal.

Why neuropathy is risky

Neuropathy reduces sensation. A blister, cut, or pressure point may not hurt, allowing it to worsen unnoticed. Poor circulation and high blood sugar make infection more likely and delay closure.

Daily prevention habits

• Check both feet every day, including between toes
• Keep feet clean and dry
• Wear well-fitting footwear and do not walk barefoot
• Avoid cutting corns or calluses yourself
• Seek care early for redness, swelling, discharge, or skin breakdown

When it is urgent

Black tissue, spreading redness, fever, foul smell, increasing discharge, or a deep ulcer requires urgent assessment. Early treatment can preserve more options.
