Gout can cause gouty nephropathy, urinary tract stones, metabolic syndrome and other complications. 1. Gouty nephropathy: When persistent high uric acid, sodium urate crystals are deposited, activating the renin-angiotensin-aldosterone system, damaging the endothelial cells, inflammatory reactions, renal interstitial fibrosis, etc., which leads to chronic urate nephropathy. It is mostly manifested as increased nocturia, edema, anemia and so on. 2. Urinary stones: uric acid concentration is oversaturated in the urinary system deposits to form stones, stones can cause obstruction, urination difficulties, hematuria, renal colic and so on. 3. Metabolic syndrome: abnormal metabolism in the body, hypertension, hyperlipidemia, obesity and so on. Gout patients must control uric acid to prevent urate deposition, uric acid stone formation and kidney damage. It is recommended that gout patients go to the hospital in a timely manner, in accordance with the doctor’s instructions for standardized treatment, to avoid delaying the condition.
