How to keep kidneys healthy?

  1. Don't overload our kidneys with excess solutes.

    No eating excess amount of protein for it leads to production of toxic substances of metabolism needed to be excreted by the kidneys. In adults, protein intake is about 1 gm per kg per day. More is needed in children to provide protein for growth. (rough estimation: 1 oz = 30mls = 30 gms).

  2. Take good quantity of fluid.

    Good fluid (water) intake results in good urine output. This decreases the risk of stone formation and also minimizes the chance of bacterial infection through its attendant fluxing action. Deep colour urine signifies concentrated urine resulted from suboptimal fluid intake. Light colour urine usually implies adequate fluid. Colourless urine is produced after taking a large amount of fluid. Too much fluid is undesirable as it flushes out electrolytes and urea in the kidneys.

  3. Don't hold the bladder when one feels the urgency to void.

    Keeping urine unduly long in the bladder may facilitate bacterial infection. This may also result in bladder muscle dysfunction in the long-term.

  4. Maintain a good bowel habit by taking a good quantity of vegetables and fruits for constipation may lead to bladder dysfunction which may promote urinary tract infection

  5. Hypertension, proteinuria and high serum lipid level are bad to the kidney. Early detection and treatment is necessary. Hypertension may be related to ingesting excessive amount of salty food. So do not eat unduly salty or unduly fatty food.
