Causes
Diabetes can damage the nerves of the legs and feet so that you may not feel a blister or sore when it begins to appear. If undetected, the sore may become larger and infected. This may lead to an amputation of a toe , a foot, or even a leg.
Risk Factors
The following factors increase your chance of developing diabetic foot ulcers. If you have diabetes and any of these risk factors, tell your doctor:
- Neuropathy (numbness, tingling, or burning sensation in your feet)
- Peripheral vascular disease (poor circulation in your legs)
- Improperly fitted shoes
- A foot deformity
- A history of smoking
