Having diabetes means you're at a much greater risk of developing foot problems. This is because raised blood glucose, also known as blood sugar, can damage the sensation in your feet. It can also affect your circulation, which can mean blood can't flow around your body properly, especially to your feet. Without a good blood supply, you may have problems with cuts and sores healing. You may also get cramps and pain in your legs or feet. These could be signs of a serious foot problem and if you don't get them treated they could lead to foot ulcers, infections and, at worst, amputations. The skin, circulation and nerve supply of your feet and legs should be examined by a healthcare professional at least once a year.
