Uric acid

Uric acid is a waste product that results from normal body processes and is also found in some foods. Normally, the kidneys eliminate uric acid from the body in urine.

A buildup of uric acid in the body may cause kidney stones, kidney damage, or a form of arthritis called gout. This may occur when the body produces too much uric acid or when the kidneys cannot eliminate uric acid adequately.

Medicine and diet changes can reduce the amount of uric acid in the body.
