![]() ![]() Most people with kidney disease get anemia. Red blood cells carry oxygen from your lungs to all parts of your body. Anemia means your body does not have enough red blood cells. ![]() But once your kidneys are damaged, they may not be able to do that very well. Your kidneys help control blood pressure. In fact, most people with kidney disease do not die from kidney failure - they die from heart disease. Heart disease is common in people with kidney disease. Having kidney disease is very serious - even without diabetes. Kidney disease that is caused by diabetes is called “diabetic kidney disease.” It is the number one cause of kidney failure in the United States. As your kidneys get less blood, less waste and fluid is taken out of your body. Over time, high blood sugar can cause these blood vessels to get narrow and clogged. Your kidneys are filled with tiny blood vessels. They keep the things you need inside your body, but filter out wastes and extra fluid. Think of your kidneys like a coffee filter. If sores don't heal and get infected, it can lead to amputation. Poor blood flow makes it hard for a sore or infection to heal. Another way that diabetes can cause damage to your feet is from poor blood circulation. Nerve damage stops you from feeling pain or other problems in your feet. Damaged nerves may stop sending pain signals. Having high levels of sugar in your blood for many years can damage the blood vessels that bring oxygen to some nerves. Nerves carry important messages between your brain and other parts of your body. This can lead to a heart attack or stroke. Fat can build up in the blood vessels as well. High blood sugar may also harm larger blood vessels in your body that supply oxygen to your heart and brain. This can result in vision problems or blindness. Having high levels of sugar in your blood for a long time can harm the tiny blood vessels in your eyes. Damage to blood vessels occurs most often in the eyes, heart, nerves, feet, and kidneys. Now imagine how sugar "sticks" to your small blood vessels and makes it hard for blood to get to your organs. ![]() Imagine what happens to sugar when it is left unwrapped overnight. High blood sugar can cause damage to very small blood vessels in your body. This is called "hyperglycemia" (high blood sugar). If your diabetes is not well controlled, the sugar level in your blood goes up. ![]()
