Kidney Stone

Kidney stones are clumps developed from solidified crystals in the kidney or urinary tract. The urine has all the ingredients that form the stone, but all these ideally pass through without our knowledge. When there is an imbalance in any of these substances, the crystals cluster together into stones. The size of the stone can be as small as a grain of sand to one as large as the size of a golf ball. The most commonly found kidney stone in humans is usually made of calcium oxalate. Other rare varieties of kidney stones include those made up of cystine, struvite (magnesium, ammonium and phosphate), calcium phosphate, uric acid, etc.

Causes of Kidney stone formation

Certain foods may promote stone formation in people who are susceptible. This stone formation is enhanced when there is increased intake of calcium, calcium oxalate, uric acid or salt in our diet, with an inadequate intake of fluids. A positive family history (genetic tendency) also makes a person prone to kidney stone formation.
