Fluid restriction can help you feel comfortable before, during, and after your dialysis sessions. Kidney dialysis gets rid of excess fluid and waste in the body. When kidneys clean waste and blood and remove extra fluid from the body, it means your kidneys are working well. Fluid restriction is also essential in the management of kidney failure.
