how does diabetic nephropathy affect the kidneys and is there a way to slow the damage?
The exact cause of diabetic nephropathy is unknown, but it is believed that uncontrolled high blood sugar leads to the development of kidney damage. In some cases, your genes or family history may also play a role. Not all persons with diabetes develop this condition. Each kidney is made of hundreds of thousands of filtering units called nephrons. Each nephron has a cluster of tiny blood vessels called a glomerulus. Together these structures help remove waste from the body. Too much blood sugar can damage these structures, causing them to thicken and become scarred. Slowly, over time, more and more blood vessels are destroyed. The kidney structures begin to leak and protein (albumin) begins to pass into the urine. Persons with diabetes who have the following risk factors are more likely to develop this condition: * African American, Hispanic, or American Indian origin * Family history of kidney disease or high blood pressure * Poor control of blood pressure * Poor control of blood suga
