Diet for a baby with multicystic kidney



My eight months old daughter`s right kidney is multicystic and left one is normal. What type of diet should we give to our baby? Kindly reply.


You will receive two responses. The good news is that your baby has a one healthy normal kidney. One healthy kidney is sufficient for a human of any size. As you have likely been told, the affected kidney will shrink in size and function over time while at the same time, the size of the normal kidney will likely increase.

No special diet is needed if kidney function is normal in the unaffected kidney. Because the failing kidney may cause high blood pressure, it's a good idea to avoid giving your child additional salt. Limiting salt intake is a good idea for most of us as well. 

It will, however, be very important to carefully measure all of your daughter's medications to protect the good kidney from damage. All medications go through the kidneys for both processing and elimination. Excessively high doses of medications can harm kidney function. One of the most commonly overdosed drugs is ibuprofen (Advil, Motrin). Also, as she grows older and becomes involved in sports, it will be critical to protect her good kidney by avoiding her participation in contact sports.
