What Is a Diabetic Foot Ulcer?

Foot ulcers will affect an estimated 19-34% of all people with diabetes during their lifetime. If you live with diabetes, knowing the causes and symptoms of foot ulcers can help you protect your feet and avoid complications like infection and amputation.

Why Do People With Diabetes Get Foot Ulcers?

A foot ulcer is an open sore or wound located on the bottom of the foot. A diabetic foot ulcer is an ulcer that heals slowly or doesn’t heal at all due to diabetes.

Risk Factors of a Diabetic Foot Ulcer

Treatments for a Diabetic Foot Ulcer

A podiatrist usually treats diabetic foot ulcers. The treatment methods used will vary based on the severity of the ulcer.

Potential treatments for diabetic foot ulcers include staying off your feet, wearing custom orthotics or shoe inserts, and wearing a cast or foot brace. Your podiatrist may also drain fluid or pus from the ulcer, prescribe antibiotics to control the infection, and perform debridement or surgery to remove dead skin, foreign objects, bone, or other abnormalities causing the ulcer.
