Common prevention methods for high uric acid in patients are as follows: 1. Reduce exogenous uric acid intake: Patients should reduce the intake of seafood, beer, foods high in animal protein and fat, as well as animal offal, so as to reduce the intake of exogenous uric acid and lower the blood uric acid and urinary uric acid content; 2. Drink a lot of water: Patients should ensure that they drink more than 2000mL of water daily, which can reduce the production of uric acid and lower uric acid; 3, Alkalinize urine: Patients should maintain urine pH at 6.5-6.8, which can be improved by taking medications, such as potassium bicarbonate, and sodium bicarbonate, or baking soda; 4. Inhibit uric acid: Patients can take oral medications, such as allopurinol, to reduce or inhibit the production of uric acid. Patients with high uric acid are usually caused by abnormal uric acid metabolism or intake of foods with high exogenous uric acid content, resulting in high uric acid in the blood or urine.
