Diabetics are at greater risk of infection than the general population. Diabetics are also prone to foot ulceration since they may not have protective sensation in their feet. Foot ulcers are caused by excessive pressure or rubbing against the skin from things like poor-fitting shoes, walking barefoot, or stepping on a sharp object.

The key factors in treating diabetic foot ulcers include:

• Prevention of infection
• Taking pressure off the area
• Removing dead skin and tissue
• Applying medication and/or dressings to the ulcer
• Managing blood glucose and other health problems
