    The development of diabetic foot ulcers is multifactorial. Since poorly controlled diabetes can cause nerve damage, the resulting neuropathy (dysfunction of peripheral nerves) causes foot deformities, dry skin, and decreased sensation. Moreover, diabetes can impair the body’s ability to heal. As a result, a callus (thickened skin) develops. Over time, constant pressure on that callus damages the skin, producing an ulcer.[1]
