Uric acid is the metabolic end product of purine in the body, and the common reasons for the increase of uric acid are as follows: 1. The production of uric acid is increased, which is mostly seen in genetic diseases, because of the disorder of purine metabolism in the body, the production of uric acid is increased. 2、 The excretion of uric acid is reduced. Because uric acid is generally excreted by the kidney, the excretion of uric acid may be reduced when the kidney is diseased, which is common in patients with glomerulonephritis. 3、 Dietary factors, dietary factors are common in patients who eat animal viscera, seafood, and drink beer.
