If the patient has high uric acid for a long time, it will cause damage to various organs and tissues, such as gout, kidney stones, and renal insufficiency. As for the causes of high uric acid, the causes are also complex. The cause of primary uric acidemia may be related to the defect of enzymes involved in uric acid metabolism. Generally, after eating a large number of foods with high purine, such as viscera and seafood, patients are particularly prone to excessive uric acid production, and some are related to decreased uric acid excretion, For example, the patient has renal insufficiency, so uric acid excretion will be reduced. For patients with high uric acid, diet must be controlled. Generally, for mild hyperuricemia, diet is mainly controlled.
