Uric acid is divided into blood uric acid, uric acid, the normal range of uric acid is usually 1.5-4.4mmol/24h, the normal value of blood uric acid is 150-416μmol/L for men and 89-357μmol/L for women, uric acid 630μmol/L usually refers to blood uric acid, both men and women, are far beyond the normal range, belong to a relatively high level, usually considered to belong to hyperuricemia that requires aggressive intervention. Blood uric acid 630μmol/L is closely associated with obesity, diabetes, hypertension, gout, coronary heart disease, cerebrovascular disease, chronic kidney disease and other diseases. When blood uric acid levels are high, urate crystals may precipitate, which, if deposited in the joints, can cause gouty arthritis, such as joint deformation. If deposited in blood vessels, they usually irritate the walls of blood vessels, leading to atherosclerosis of arteries and triggering or aggravating coronary heart disease. If deposited in the kidneys, it usually causes gouty nephropathy, uric acid stones, and can induce uremia in severe cases. Patients with blood uric acid level of 630 μmol/L need to improve their lifestyle and limit the intake of high purine diet, such as animal offal, soy, strong tea and beer. Patients are advised to drink more water and keep the daily water intake above 2000ml to promote blood uric acid excretion. If improvement through lifestyle is ineffective, medication is needed. Drugs such as benzbromarone can be used to increase blood uric acid excretion, drugs such as allopurinol can be used to make blood uric acid production decrease, and drugs such as sodium bicarbonate can be used to alkalize urine to increase blood uric acid excretion.
