DefinitionBy Mayo Clinic Staff
A high uric acid level, or hyperuricemia, is an excess of uric acid in your blood. Uric acid is produced during the breakdown of purines, which are found in certain foods and are also formed by your body.
Once produced, uric acid is carried in your blood and passes through your kidneys, where most of it is filtered out into the urine.
About one in five people has a high uric acid level. It may be related to attacks of gout or the development of kidney stones. But most people with high uric acid levels don't have any symptoms or related problems.
