The kidneys are responsible for filtering waste products from the blood. During hot summer days, your body tends to sweat more. Thus, less water needs to be excreted through the kidneys. Again, on cold winter days, your body sweats less. So, urine output needs to be greater in order to maintain the proper balance within the body. It is the kidney’s job to regulate fluid balance by adjusting urine output. Sometimes, there are situations when the kidneys fail to filter the blood effectively, and fluid and waste products get collected in the body to such a critical level a person may need to start dialysis. The two main causes of kidney failure and need for dialysis treatment are high blood pressure and diabetes. Dialysis is a procedure that acts as a substitute for many of the normal functions of the kidneys. Dialysis facilities at Sunrise Hospitals can allow individuals to live productive and useful lives, even though their kidneys are no longer functioning properly.
