Is Kidney more eligible to youths or the elderly?

How can it be controlled?

Unfortunately Kidney stones are common in both adults as well as young folks, 

Some factors that increase the chances are,

Heredity, Geographical location, Diet, like foods high in calcium,

And finally some certain meds, like those who consume excess

calcium-containing antacids can increase the amount of

calcium in their urine and increase their risk of forming stones, Hope this helps.
