Sometimes, hard bits called stones grow inside the body. These are called kidney stones. They form in the kidneys when there are too many minerals in the urine. This can happen if you do not drink enough water.

Stones form in a few steps. First, tiny crystals form. This is called nucleation. Next, the crystals grow larger. Finally, many crystals clump together. This clumping is called aggregation.

Small stones may pass out of the body without any pain. But larger stones can cause a blockage. This can lead to renal colic. This is a type of very sharp pain in the lower back. It can also move toward the groin.
