Q: Can diabetes affect healing of sores on the foot?

A: Yes, it can. When blood sugars are in a good range of about 80-120, sores on the foot typically heal in a timely fashion (as long as the blood flow into the feet and legs is good). However, if blood sugars run high, especially over 200, it becomes more difficult for the body to heal from sores. Podiatrists can help treat diabetic foot wounds, but it is also important for diabetic patients to work closely with their primary care physicians and/or endocrinologists to keep their blood sugars in good control.
