What role do the kidneys play in diabetes type 2?
Diabetes is the leading cause of kidney disease. About 1 out of 4 adults with diabetes have kidney disease. The main job of the kidneys is to filter wastes and extra water out of your blood to make urine. Your kidneys also help control blood pressure and make hormones that your body needs to stay healthy. When your kidneys are damaged, they can’t filter blood like they should, which can cause wastes to build up in your body. Kidney damage caused by diabetes usually occurs slowly, over many years. High blood glucose, also called blood sugar, can damage the blood vessels in your kidneys. When the blood vessels are damaged, they don’t work as well. Many people with diabetes also develop high blood pressure, which can also damage your kidneys. You can take steps to protect your kidneys and to prevent or delay kidney damage by stopping smoking, working with a dietitian to develop a diabetes meal plan and limit salt and sodium. You make physical activity part of your routine; you stay at or get to a healthy weight; you get enough sleep, 7 to 8 hours of sleep each night.
