A health alert tonight involving kidney stones.
You're more than twice as likely to have one compared to almost two decades ago.
UCLA Researchers say obesity is to blame for the dramatic increase in kidney stones especially in people who eat a lot of salty foods and meat.
They're also more likely to develop diabetes or gout.
Warning signs include a painful cramping in your back or side.
Doctors say you can prevent them by drinking a lot of water with lemon juice cut down on salt and don't eat meat everyday.
According to Dr. Andrew Weil, here are a few ways to lower your chance of developing kidney stones:
•Avoid caffeine, which seems to increase urinary calcium.
•Decrease consumption of animal protein, especially red meat, which increases the risk of stone formation.
•Limit your salt intake (salt increases urinary calcium excretion).
•Consume potassium and bran fiber in foods, not supplements, because both can reduce urinary levels of calcium.
•Take calcium citrate, which may bind with oxalates in the intestines and be eliminated as calcium oxylate.
•Drink lemon juice in sparkling water, as lemon juice is a natural source of citrate.
