Chronic hyperuricemia may lead to gout. If the blood uric acid level is 423µmol/L, gout may be triggered if there is urate deposition in the tissues of the body. If long-term hyperuricemia is uncontrolled, it is also prone to induce hypertension, diabetes, coronary artery disease and other various complications.
