Diabetes, especially type 2 diabetes, it has become so common that diabetic kidney disease (nephropathy) has jumped ahead of high blood pressure as the leading cause of kidney failure in much of the world.
Kidney failure is a serious matter: the work of the kidneys is to filter waste products and excess fluid from the blood circulating through the body. If the kidneys fail, survival depends on dialysis (be connected to a machine for making blood-filtering kidneys) or a kidney transplant.
glucose levels in the blood can damage blood vessels throughout the body, including the small blood vessels that make the kidneys filtering. When the small vessels are damaged, they can not do the job properly. High blood pressure can cause and worsen the problem, damaging more blood vessels and accelerate the progression of kidney disease. Both kidneys are affected.
