Uric acid is a product of purine metabolism. Under normal circumstances, uric acid production and excretion are in a dynamic balance, and the body maintains a normal range of blood uric acid concentration. When too much uric acid is produced or too little is excreted, this dynamic balance can be disrupted, causing hyperuricemia. The causes of hyperuricemia are as follows: First, excessive production of uric acid, if you often eat too much high purine diet, such as meat, broth, seafood, beer and other high purine food, it can cause the body to produce too much uric acid resulting in hyperuricemia. Second, if you also suffer from leukemia or malignant tumor chemotherapy history, etc., because of the massive destruction of cells can also lead to high uric acid. Third, too little uric acid excretion, when kidney disease caused by uric acid excretion disorder, will also lead to hyperuricemia.
