Kidney disease is one of the common complications of diabetes. About 20%-30% patients with diabetes turn into kidney disease at last. So it is important for you to manage your diabetes well. Why does diabetes increase the risk for kidney disease?
What is diabetes?
Diabetes occurs when the body begins to have a problem with insulin. Insulin is a hormone that helps the blood sugar get into your cells to give them energy. There are two types of diabetes. With type 1 diabetes, your body does not make insulin. With type 2 diabetes, the more common type, your body does not make or use insulin well. Without enough insulin, the glucose stays in your blood, resulting in high blood sugar. Both types can lead to kidney damage, if not properly treated.
The influence of diabetes on kidneys
High blood sugar can cause serious problems to kidneys, because the blood vessels in the body that are used to process wastes become clogged with excess sugar in the blood so that the vessels do not let the filters in the kidneys work as well as they should. Over time the small blood vessels are injured. Once the blood vessels in the kidneys are injured, your kidneys can not filter the wastes in your body, leading to weight gain, edema, proteinuria and so on.
It can also damage the nerves in your body. This can cause difficulty in emptying your bladder. The pressure resulting from your full bladder can injure the kidneys. Besides, if urine remains in your bladder for a long time, bacteria in urine will rapidly grow, causing infection.
Therefore, it is very important to control the blood sugar levels, which is helpful for slowing down the development of diabetic nephropathy.
