The human anatomy comprises of two bean shaped kidneys. Kidneys are about the size of a fist and are located on left and right side of the spine. The main function of the kidney is to filter the blood, by removing waste and excess water that is expelled by the body in the form of urine. This is important as it helps to regulate blood pressure, and to keep the balance of salt and minerals in the body.
When kidneys are damaged, fluid and waste tend to build up in the body and this can cause swelling, vomiting and fatigue. The main risk factors associated with kidney disease are diabetes, high blood pressure and cardiovascular disease.
