The uric acid value should not exceed 420 μmol/L in normal men and 350 μmol/L in normal women. If the fasting blood uric acid is higher than normal in more than two examinations in a normal purine diet state, hyperuricemia should be considered. Hyperuricemia is divided into exogenous and endogenous. Endogenous increased uric acid may be caused by disorder of purine metabolism and reduced uric acid excretion, while exogenous is usually related to diet, such as frequent drinking, eating broth, hot pot, eating animal offal, seafood products, etc. Therefore, when increased uric acid is found at the time of examination, diet should be controlled first, such as reducing the above-mentioned high purine foods, not drinking alcohol, and taking care to drink more water to increase uric acid excretion. If the uric acid cannot be controlled within the normal range through diet, you should consider using uric acid-lowering drugs for treatment, and review the blood uric acid index regularly to evaluate the effect of treatment.
