Watermelon may help get rid of kidney stones

Condition analysis:
Kidney stones are made of salts and minerals in the urine that stick together to form small "pebbles." They can be as small as grains of sand or as large as golf balls. The medical term for this condition is nephrolithiasis, or renal stone disease.

Kidney stones form when there is a high level of calcium (hypercalciuria), oxalate (hyperoxaluria), or uric acid (hyperuricosuria) in the urine; a lack of citrate in the urine; or insufficient water in the kidneys to dissolve waste products. The kidneys must maintain an adequate amount of water in the body to remove waste products. If dehydration occurs, high levels of substances that do not dissolve completely (eg, calcium, oxalate, uric acid) may form crystals that slowly build up into kidney stones.
The chemical composition of stones depends on the chemical imbalance in the urine. The four most common types of stones are comprised of calcium, uric acid, struvite, and cystine.

Instructions:
Watermelon: Watermelon may help get rid of kidney stones and is an easy, natural remedy to use. Watermelon may be most effective against stones comprised of calcium. Since calcium stones are the most common, there is a good chance that’s what you’re dealing with. The potassium in watermelon is needed for healthy kidney function and may help get rid of stones. Potassium also helps regulate how acidic the urine is. Plus, watermelon contains a large amount of water, which can help flush stones out. Eat a serving or two of watermelon daily to prevent future stone formation.
