Dialysis is a medical process through which a person’s blood is cleansed of the toxins or wastes that kidneys normally remove. It is used when a person’s kidneys no longer function optimally. The purpose is to keep the right levels of chemicals, fluids and salts in the body so that the body functions normally.

Like healthy kidneys, dialysis keeps your body in balance. It removes waste, salt and extra water, keeps a safe level of certain chemicals in your blood, such as potassium, sodium and bicarbonate and helps to control blood pressure. A session of hemodialysis usually takes 4 hours three times a week whereas peritoneal dialysis is a continuous process.

While on dialysis you should watch your diet. In case of any breathing trouble you should contact your doctor as you may require urgent dialysis. Care of the vascular access should be ensured as advised by your physician.

Renal dialysis falls into two main divisions: haemodialysis and peritoneal dialysis. Hemodialysis cleans and filters your blood using a machine to temporarily remove harmful wastes, extra salt, and extra water from your body. Hemodialysis is most often performed in a dialysis centre but home treatment options are also available.

Peritoneal dialysis uses the lining of your abdomen and dialysis solution (a mixture of minerals and sugar dissolved in water) to filter your blood removing wastes, chemicals and extra water from your body. After several hours, the used solution is drained from your abdomen through a tube and the cycle is repeated with fresh solution
