Most cases of hyperuricemia usually have no obvious clinical symptoms, and it can take years to decades from the increase in blood uric acid to symptom onset, with some individuals never exhibiting obvious clinical symptoms throughout their lifetime. However, as age increases, the incidence of gout becomes higher. When accompanied by acute gouty arthritis, patients may experience severe joint pain. If blood uric acid levels remain high over a long period, this can lead to the formation of gouty tophi and uric acid stones, among other issues.
