How do foot ulcers form?
There are a combination of factors that can cause diabetic foot ulcers to form. Lack of feeling in the foot, poor circulation, foot deformities, trauma, foot irritation such as friction or pressure, as well as the ongoing disease of diabetes, can all cause foot ulcers to form on people with diabetes. 2 According to the American Diabetes Association and the American Academy of Family Physician’s, high blood pressure, high cholesterol levels and smoking can harm the circulation in your feet and keep sores from healing.
