Dialysis is prescribed when the kidneys are in failure, or only 10%-15% of normal kidney function remains. Your kidneys are responsible for removing waste and other fluids and minerals in the body. When the kidneys are not functioning properly, this waste builds up in the body and causes several complications. These complications include heart failure, high levels of potassium or calcium in the blood, too much fluid in the lungs, loss of appetite, and vomiting. If other methods of treating kidney failure are insufficient, your doctor may prescribe dialysis.

Starting dialysis can be an overwhelming experience and it can be less stressful with support from family, friends, and an experienced dialysis center staff (which includes a nephrologist, nurse, dialysis technician, social worker, and a dietitian).
When you are on dialysis, your diet will be different. You will need to monitor the amount of sodium, potassium, phosphorus, calcium, protein, and calories you eat. The dietitian will meet with you to review your individual nutrient needs based on your medical history, food and cultural preferences, height, weight, and laboratory values.

A dialysis machine mimics some of the functions of a human kidney. A primary job of kidneys is to remove urea and certain salts from blood so they can exit the body in urine.
A dialysis machine removes blood from the patient and runs it through tubes made of a semi-porous membrane. On the outside of the tubes is a sterile solution made of water, sugars and other components. Certain substances including red blood cells, white blood cells and other important blood components cannot fit through the pores in the membranes because those components are too large. The urea and salt, however, flow through membranes easily and are removed through the sterile solution.
