what happens when no blood flow to foot
Poor foot circulation is sometimes caused by obesity, lack of exercise, or poor food choices. These habits can cause the arteries that carry oxygenated blood and nutrients around the body to become diseased. A diseased artery narrows, preventing the easy flow of blood to organs and muscles.
Many people with diabetes have peripheral arterial disease (PAD) , which reduces blood flow to the feet. Also, many people with diabetes have nerve disease, which reduces sensation. Together, these problems make it easy to get ulcers and infections that may lead to amputation.
