Because of reduced blood flow, people with PAD are more likely to have foot problems. Minor problems such as cuts, sores or blisters may not heal quickly or heal at all.
Diabetes further increases the risk of people with PAD for foot problems. In addition to poor circulation to their feet and legs, they also may have nerve damage from high blood glucose levels. This nerve damage (or diabetic neuropathy) can cause loss of sensation in the feet. A person may not feel a small rock inside his or her sock that is causing a sore or a blister caused by poorly fitting shoes.
For people with peripheral artery disease and diabetes, minor foot injuries can turn into serious infections. If these sores are not treated right away, they may lead to amputation of a toe, foot or leg. With PAD, you can prevent serious foot problems by taking care of your feet every day.
