Clinical Information

Diabetic foot ulcers are a type of foot ulcer wherein those with diabetes, due to poor circulation in one’s feet, develop lesions or open sores that take a while to heal, get infected easily, or often come back. Said ulcers are said to be the leading cause of amputation to prevent the spreading of an infection to the rest of the body.
Aside from having poor circulation, nerve damage, and wounded feet, patients with diabetes have a higher risk of developing foot ulcers if they have poor hygiene/quality shies, consume alcohol/tobacco often, have heart disease, have kidney disease, and are obese.
Symptoms of a neurotropic or diabetic foot ulcer are black tissue or gangrene (partial or complete) around the ulcer.
Practitioners utilize the Wagner Ulcer Classification System, a scale from 0 to 5, to determine the seriousness or severity of one’s ulcer.
Common treatments, aside from having the patient wear protective items, are medication and surgery.

Synonyms Include:
