Diabetic Foot Ulcer
Ulcers are slow healing wounds on the skin. Diabetic foot ulcers occur on the feet of people with type 1 and type 2 diabetes. Up to 15% of people with diabetes are at risk for developing foot ulcers. Diabetic foot ulcers usually occur on the bottom of the foot.
The sooner a diabetic foot ulcer is treated, the better the outcome. Ulcers that do not heal or develop a severe infection may lead to amputation of the foot. About 80% of leg amputations in the US started off as diabetic foot ulcers.

Diabetes can damage the nerves of the legs and feet. This may make it difficult to feel a blister or sore. If you don't care for a sore it may become larger and infected.
Diabetes also can causes problems with blood flow. Poor blood flow can make it difficult to heal.
The ulcer itself is usually caused by:
- Repetitive trauma or pressure on the foot
- Puncture wound on the foot
- Objects in the shoe that can damage the skin (such as a small rock)
