The diet of patients with high uric acid should pay attention to control the total calorie intake of food, limit the consumption of alcohol and high purine food (such as heart, liver, kidney, etc.) a large number of intake, drink more than 2000ml of water per day to increase the excretion of uric acid, and so on. Uric acid is the end product of purine metabolism, mainly by the cellular metabolic decomposition of nucleic acids and other purine compounds and purines in food by the role of enzyme decomposition and production. In addition to paying attention to diet, patients with high uric acid should be careful to use drugs that inhibit uric acid excretion, such as thiazide diuretics, etc., to avoid triggering factors and active treatment of related diseases. Blood uric acid levels should be closely monitored during radiotherapy or chemotherapy. Patients with high uric acid should actively cooperate with their doctors to maintain a healthy diet and lifestyle.
