Complications of Diabetes
Monday, January 4th, 2010
Too much sugar in the blood for a long time causes complications of diabetes. High blood sugar can damage many parts of the body, such as the heart, blood vessels, eyes, nerves and kidneys. Diabetes problems can be scary, but there is a lot you can do to prevent them or slow them down.
High blood sugars can cause feet and skin problems High blood sugar causes two problems that can hurt your feet:
1. Nerve damage. First problem is damage to nerves in your legs and feet. With damaged nerves, you might not feel pain, heat, or cold in your legs and feet. You might let a sore or cut on your foot get worse because you do not know it is there. This lack of feeling is called diabetic neuropathy. It can lead to a large sore or infection.
2. Poor blood flow. The second problem happens when not enough healthy blood flows to your legs and feet. Poor flow makes it hard for a sore or infection to heal. This problem is called Peripheral vascular disease. Smoking when you have diabetes makes blood flow problems much worse.
These two problems can work together to cause a foot problem.
One in five diabetics get a foot problem. For example, you get a blister from shoes that do not fit. You do not feel the pain from the blister because you have nerve damage in you foot. Next, the blister gets infected. If blood sugar is high, the extra sugar feeds the germs. Germs grow and the infection gets worse. Poor blood flow to your legs and feet ca slow down healing. Once in a while a bad infection never heals. The infection might cause gangrene. If a person has gangrene, the skin and tissue around the sore die. The area becomes black and smelly.
To keep gangrene from spreading, a doctor may have to do surgery to cut off a toe, foot, or part of a leg. Cutting off a body part is called an
amputation.
Anyone can have corns, blisters, and athlete’s foot. If you have diabetes and your blood sugar stays high, these foot problems can lead to infections.
