Diabetic Foot Ulcer: Causes
Copyright © Nucleus Medical Media, Inc.
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 cause 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
