Blood uric acid is 670 μmol/L. It is possible to return to normal with active dietary control and medication. Uric acid is the end product of purine metabolism. When urate production is excessive and/or renal excretion of uric acid is reduced, the concentration of uric acid in the blood will increase, resulting in hyperuricemia. Poor dietary habits, which can lead to increased uric acid production, such as excessive consumption of purine-rich foods (animal offal, kidney, anchovies, beer, seafood, etc.), can lead to excessive exogenous purine intake. Patients with hyperuricemia, need to actively adjust the diet structure, limit or avoid consumption of purine-rich foods, and pay attention to a large number of drinking water, can increase the excretion of uric acid. For patients with elevated blood uric acid, drugs such as benzbromarone can be used to inhibit the reabsorption of urate in renal tubules and increase the excretion of uric acid, and drugs that inhibit uric acid production (allopurinol, etc.) can also be used to inhibit xanthine oxidase and inhibit uric acid production. Blood uric acid for 670μmol / L patients are recommended to the regular hospital rheumatology and immunology department in a timely manner, the drugs need to be used under the guidance of a professional doctor.
