Diabetic Foot Infections
Foot problems in people with diabetes are common.
Simple issues such as scrapes, crooked toes, bunions, and deformed nails can become complicated and result in a break in the skin and an open wound. Loss of feeling in the feet, called neuropathy, and poor circulation in arteries or veins can add to the development of infections.
In diabetic patients, open wounds can easily become infected. These problems are the result of the long-term effects of diabetes and compromise of the circulation.
The role of the vascular surgeon is to assess circulation and try to improve blood flow and thereby help heal the infection.
