Why does the body get kidney stones and how do they even form?

Question

I’ve tried searching this but I’m legitimately confused as to why and how kidney stones come to exist in somebody?

In: Biology

Answer 1

Kidney stones form when there is too much crystal forming substances like calcium and uric acid that the urine can’t dissolve. It builds up in the kidneys. Sometimes a body doesn’t produce enough substances that help break the crystals down.
The crystals form together into larger “stones”
