description Weight reduction may reduce serum uric acid (SUA). This study aimed to examine the changes of SUA before and after bariatric surgery in patients with obesity with or without hyperuricaemia and gout. This is a retrospective analysis of 147 routinely collected data on hospital patients with obesity who underwent bariatric surgery. The body weight and SUA were measured at baseline and after surgery at 1-7 days, 1, 3, 6 and 12 months. The mean (95% CI) weight reduction of 147 patients was 30.7 (28.7, 32.7) kg 1 year after surgery (P

Similar trends but more rapid reductions were observed in 55 hyperuricaemia patients and 25 gout patients. All 25 gout patients had an elevated SUA above the therapeutic target (≥360µmmol/l) at baseline, but in 10 patients it was reduced below this target at 12 months. The mean reduction (95% CI) of SUA in all patients and gout patients was 84.3 (63.1-105.4) and 163.6 (103.9, 223.3) µmmol/l, respectively.
