    • Most common causes are DIABETES MELLITUS, HYPERTENSION and INFECTION.
    • 2 main treatments: DIALYSIS and TRANSPLANT.
    • Dialysis: Removes WASTE, excess FLUID and SALT from blood by using a dialysis machine. PARTIALLY PERMEABLE MEMBRANE that allows exchange of substances between BLOOD and DIALYSIS FLUID.
    • HAEMODIALYSIS: Blood from a VEIN passed into machine with an ARTIFICIAL dialysis membrane. HEPARIN added to avoid clotting.
    • PERITONEAL dialysis: Implants a permanent TUBE into the ABDOMEN. Dialysis SOLUTION poured into tube. After a few hours, used solution is drained and fresh is added.
    • Kidney TRANSPLANT: Can be REJECTED as immune system recognises it as foreign. Patients given IMMUNOSUPPRESSANT drugs to help prevent rejection.
    • Advantages of kidney transplants: Diet is less limited, freedom, better quality of life, no longer seeing self as chronically ill.
    • Disadvantages of kidney transplants: Need immunosuppressants, major surgery, risks of surgery, frequent checks, side effects.
