What Causes Foot Ulcers

Foot ulcers are caused by skin tissue breaking down to explore the layers beneath, possibly even all the way to the bone. They usually develop on big toes and the balls of the feet, though they can develop anywhere on the foot.

Diabetic ulcers are commonly caused by poor circulation, a form of vascular disease in which blood doesn’t flow to your feet properly; nerve damage, which removes the pain that could have warned about the wounds that develop into ulcers; high blood sugar, which can slow down the healing of wounds and the ability of the body to fight of infection; and irritated or wounded feet, which can become infected and develop into ulcers or other problems.
