Kidney Disease, Renal Disease
The function of your kidneys is to filter your blood. The actual parts of the kidney that do the filtering are called the nephrons. When the nephrons take the waste and extra water from the blood, it makes urine. When the nephrons no longer function you have kidney disease. The waste and extra water back up into your system and your body becomes toxic.
Kidney disease usually develops over a long period of time and the symptoms are not always obvious. Your chances of developing kidney disease increase if you have a family history of the disease, if you have high blood pressure or hypertension, or if you have diabetes.
Depending on the severity of the disease, you may have to undergo dialysis or a kidney transplant to replace the filtering function of the nephrons.
