The causes of high uric acid are generally common in daily life, and there are many factors that can cause high uric acid, including the following: First, eating more purine foods. High-purine food, eaten for a long time or eaten too much at one time, leads to high uric acid production, which can not be excreted in time, causing uric acid to rise in the body. Second, the patient's uric acid excretion function decreased. The decrease of uric acid excretion function is the pathological manifestation of hyperuricemia. The cause of high uric acid is disease, mostly due to the decline of renal function. It is common that the excretion function of renal tubules decreases when uric acid is removed, which leads to endless uric acid excretion and high uric acid value. Third, the factors of irregular life. Irregular lifestyle will lead to high uric acid value, which is not very serious. Patients can recover uric acid value in a short time by improving their good diet, and under normal circumstances, no treatment is needed.
