Uric acid down to how much depends on the patient’s own situation, if there is no underlying disease is generally to be reduced to 360 μmol / L; if there is an underlying disease is generally reduced to 300 μmol / L is more appropriate, specific advice to consult a professional doctor. Uric acid is the product of purine metabolism, when the blood uric acid concentration is too high, uric acid is easily deposited in the form of sodium salt in the joints, soft tissues, etc., causing inflammatory reactions and the formation of gout. The normal value of uric acid in adult men is 150～416μmol/L, and in women is 89～357μmol/L. Clinically, under normal circumstances, if the uric acid level in fasting blood is more than 420μmol/L when measured on 2 occasions not on the same day, it can be diagnosed as hyperuricemia. The value of blood uric acid to reach the standard is different for different patients. If patients do not have underlying diseases, they should control the uric acid below 360μmol/L for a long period of time, which can reduce the rate of gout attack. If patients have underlying diseases, especially cardiovascular disease, etc., they need to reduce uric acid to 300μmol/L, otherwise it is easy to increase the risk of cardiovascular disease. It is recommended to standardize the treatment of lowering uric acid under the guidance of doctors. In addition, you can drink more water to promote the uric acid discharge. Eat less seafood, animal offal, sardines and other high purine food. It is recommended that patients with high uric acid should consult the rheumatology and immunology department in a timely manner, under the guidance of the doctor for standardized treatment and regular follow-up.
