(HealthDay News) -- One in ten people will have a kidney stone at some point in their lives, says the National Kidney Foundation. Kidney stones are hard objects that are produced from chemicals in urine.

Symptoms can range from lower back pain, bloody urine, vomiting or fever and chills. Possible causes of kidney stones are drinking too little water, obesity, weight loss surgery, or eating food with high salt or sugar content.

If you think you have a stone, see a doctor as soon as possible. He or she may recommend that you drink extra fluids to flush out the stone.
