The body produces uric acid when it metabolizes chemical compounds called purines. Too much uric acid in the bloodstream is called hyperuricemia. In certain people, hyperuricemia can lead to gout, a common form of arthritis. Hyperuricemia may develop for one or a combination of reasons:

Your body produces too much uric acid. When a body produces too much uric acid, there is typically a genetic cause.
Your kidneys are not able to adequately filter and flush out uric acid from the bloodstream.
You consume foods and beverages that are high in purines.
