When we are healthy, our kidneys act as regulators and discharge excess levels of water and minerals as waste. However in some people this process is affected if their kidneys have failed or damaged. A Dialysis treatment may be used as an option for such people. Dialysis is the artificial process of eliminating waste and unwanted water from the blood. There are two types of dialysis procedure - Hemodialysis and Peritoneal dialysis. A urologist is the best person to recommend the type of treatment. In hemodialysis, the blood is taken out of the body through a tube and is run through a series of filters. This purified blood is then returned back to the patient through another tube. In effect a patient is connected to an artificial kidney. The procedure usually lasts about 3 to 4 hours each week. In peritoneal dialysis, a dialysate solution is run through a tube and is deposited in the peritoneal cavity and the abdominal cavity around the intestine. Peritoneal cavity acts as a natural filter and this dialysis effectively uses this function to filter out the toxins. The dialysate, which absorbs all the waste, is later drained out through a tube and discarded. Though this is not efficient as a hemodialysis, it is carried out for longer periods as this restricts the frequent visits to the clinic. Though dialysis helps in the purification it's not effective as a normal kidney. Changes to the life style and food habits are needed to lead a normal life.
