Most of the time, high uric acid does not come down because the diet is not strictly controlled, and partly because the medication is not strictly used according to medical advice. Many patients with high uric acid need to take long-term treatment with uric acid-lowering drugs to be able to control uric acid within the target range, some patients do not pay attention to diet after control, usually eat more meat, and some even drink alcohol, so uric acid always fails to come down. If the uric acid is higher than 420μmol/L, it is called hyperuricemia, and hyperuricemia can easily lead to gouty arthritis and also cardiovascular disease, so usually we should have a strict low purine diet, not to eat animal offal, seafood, and not to drink alcohol, especially beer. If it cannot be lowered to the normal range through dietary control, long-term treatment with uric acid-lowering drugs is recommended.
