MYTHS AND FACTS ABOUT KIDNEY DISEASE

Myth : All kidney diseases are serious and incurable

Fact : Most kidney diseases are treatable. Some are self-limiting and occur only once in a lifetime. Some progress towards renal failure but this progression can be slowed down if the disease is detected early. Even in late cases, treatment may help in reversing or slowing down the loss of kidney function.

Myth : only one kidney is affected by kidney diseases.

Fact : All medical diseases (high BP, diabetes, glomerulonephritis, nephrotic syndrome, poisonings, infections of urinary tract etc) affect both kidneys.

Some structural diseases like tumours, stones, abscesses, renal artery or vein clots, ureteral narrowings, may affect only one kidney.

Myth : I am passing enough urine. Hence my kidneys are not obstructed.

Facts : Most obstructions of the bladder and partial obstructions of the ureter  (stones or accidental ligation during surgery) cause more urine to be formed and passed. Only bilateral total obstruction or obstruction below bladder neck cause reduced urine output.

Myth : I am passing enough urine. Hence my kidneys are healthy and I do not require treatment or dialysis.

Fact : Some kidney disease cause decreased urine output or oliguria (< 400 ml urine/day). Most, however, are nonoliguric or Polyuric (urine output > 3000 ml/day). Even with normal or large urine production, waste material like acids, potassium, urea, creatinine and many more may not be excreted. A person then may require treatment at times dialysis as well.

Myth : Drinking more water will keep my kidneys healthy. This is the treatment for kidney diseases.

Fact : Usual water intake is well managed by thirst in healthy people. Drinking 2-3 litres of fluid may avoid some stone formations and urinary tract infections. Continuing to drink fluids when kidneys are failing or have failed may cause fluid in the lungs (pulmonary edema) or poor control of hypertension. The consequences may be deadly. Follow your doctors’ advice.

Myth : Dialysis once started is required life long.

Fact : In temporary or reversible renal failure, dialysis is required till kidney recovers. In CKD or ESRD with no reversibility, dialysis is required for emergency treatment of high potassium or fluid in the lungs. Maintainance dialysis for uremic symptoms, neuropathy, encephalopathy, pericarditis etc usually means either lifelong dialysis or renal transplant.
