Blood uric acid 600 to 700 μmol / L if the high purine food intake or excessive renal excretion of uric acid caused by obstacles can generally be cured, if the metabolic pathway obstacles caused by the more difficult to cure. 1. Excessive intake of high-purine food: excessive intake of high-purine food can cause uric acid elevation. Under normal circumstances, control the intake of high-purine food and follow the doctor’s instructions with the use of drugs to inhibit uric acid production, such as febuxostat can make the uric acid back to normal. 2. Renal excretion of uric acid obstacles: taking some drugs may affect the renal excretion of blood uric acid, such as cyclosporine, hydrochlorothiazide, etc., such drugs will affect the renal excretion of uric acid, generally discontinue the use of drugs, the body’s blood uric acid will be restored to normal levels. 3. Metabolic pathway obstacles: If the blood uric acid metabolic link obstacles caused by hyperuricemia will be relatively difficult to cure. Generally often with high blood lipids, hypertension, diabetes, obesity and other common metabolic syndrome, in this case you want to reduce uric acid to normal levels need to treat related diseases at the same time. Blood uric acid reaches 600～700μmol/L is already a very serious hyperuricemia, and it is recommended that the patient should consult the Immunology Department in time, take treatment under the guidance of the doctor, and follow up regularly.
