It is more serious for young people to have uric acid over 800μmol/L, because the normal blood uric acid level in human is 180-420μmol/L. 800μmol/L is already much higher than the normal range, and if it is higher than 540μmol/L, you need medication to lower uric acid. Uric acid over 800μmol/L may cause gouty arthritis and also increase the risk of cardiovascular disease, so it is necessary to control blood uric acid within the normal range as soon as possible. If there is gouty arthritis, the general control goal is to control blood uric acid below 300 μmol/L. In case of simple hyperuricemia, blood uric acid can be controlled below 420 μmol/L. This requires patients with high uric acid to have a strict low purine diet, not to eat animal offal, seafood, not to drink alcohol or drinks with high fructose content, and then to take uric acid-lowering medication for treatment. For simple hyperuricemia, you can choose benzbromarone, and for gouty arthritis, you can choose febuxostat.
