What are kidney stones?

ANSWER

Kidney stones are hard, small “pebbles” of salt and mineral in your pee. They form when your body has too much of certain minerals and not enough liquid. They can be painful to pass out of your body.

The stones can be brown or yellow, and smooth or rough. They can be as small as a grain of salt or larger than a kernel of corn. Men are twice as likely as women to get them.
