Stones That Grow Inside Your Bladder

You can actually grow rocks inside your own body. These bladder stones form when minerals in your urine crystallize into solid masses that can grow large enough to cause significant pain and blockage.

While it sounds like a bizarre biological glitch, these stones usually develop because urine stays in the bladder for too long or becomes too concentrated. They can range from microscopic grains to objects the size of a golf ball. In some cases, they are caused by an underlying infection or an enlarged prostate preventing the bladder from emptying properly. It is a striking reminder of how your body chemistry can turn common liquids into hard, physical objects.
