Hyperuricemia is not a kidney disease. Hyperuricemia is a common biochemical abnormality caused by excessive urate production and/or decreased renal excretion of uric acid, or both. It may be manifested by 2 fasting blood uric acid levels measured on non-same day exceeding 420 μmol/L. It may be due to obesity, metabolic syndrome, diabetes mellitus and other causes. Nephropathy, on the other hand, refers to a variety of diseases occurring in the kidneys, which are due to various reasons for changes in the structure and function of the kidneys, resulting in pathological damage to the kidneys, abnormalities in the composition of the blood or urine, and other disorders. The two pathological mechanisms are different, so hyperuricemia is not a kidney disease. Patients with hyperuricemia are advised to go to regular hospitals in time for consultation and standardized treatment under the guidance of doctors.
