  • What is Kidney Failure?

  • Kidney failure happens when one or both kidneys

  • stop functioning normally.

  • This could be due to infections,

  • urine elimination problems

  • or some underlying diseases.

  • Instead of being excreted,

  • wastes like urea,

  • creatinine,

  • uric acid

  • and ammonium ions remain in blood.

  • Accumulation of these substances

  • is toxic to the human system

  • and could prove to be fatal

  • if not treated in time.

  • The treatments currently available

  • are dialysis or a transplant.

  • Dialysis is also called haemodialysis.

  • It is a process or procedure

  • to eliminate excess salts

  • and nitrogenous wastes from blood.

  • It does not absorb or secrete anything.

  • During dialysis,

  • the patient's blood from the modified blood vessel in his arm

  • is passed into the dialysis machine

  • and returned after being cleaned.

  • The dialysis fluid is changed regularly

  • to remove wastes

  • and to maintain a diffusion gradient

  • between the patient's blood and the dialysis fluid.

  • The dialysis machine contains the following parts:

  • a steel tub with a filter

  • filled with a warm fluid set at 37°C

  • to suit the patient's body temperature.

  • The machine also has a narrow tubular coil of cellophane

  • with pores and a sterile dialysis fluid.

  • The tubular coil of cellophane

  • is semi-permeable in nature.

  • It allows small molecules to pass through,

  • prevents blood cells and large proteins from leaving

  • and provides large surface area

  • for material exchange.

  • The sterile dialysis fluid

  • surrounds the cellophane tube

  • and contains regulated amounts of dissolved salts and sugars.

  • Once a kidney fails,

  • there are very rare chances of its healing,

  • hence this procedure has to be carried out

  • until the kidney is replaced with a new one.

  • Transplantation is a major operation

  • through which a failed or dysfunctional kidney

  • is replaced with a healthy one.

  • Kidney transplant is associated with better quality of life,

  • lower risk of death,

  • fewer dietary restrictions

  • and lower cost of treatment

  • compared to a lifetime on dialysis.

  • You can keep your kidney healthy

  • by keeping yourself active,

  • maintaining your weight,

  • controlling sugar level and blood pressure,

  • avoiding over the counter pills,

  • avoiding smoking

  • and also maintaining a healthy fluid intake.
