A new study has indicated that weight loss surgery could help to reduce a person's risk of developing gout and hyperuricaemia.
Led by Sahlgrenska University Hospital, the research aimed to assess the long-term effect of bariatric surgery on the incidence of gout and hyperuricaemia in participants of the Swedish Obese Subjects (SOS) study, looking at 1,982 subjects who underwent surgery and 1,999 obese patients who did not.
Gout is a painful form of arthritis in which small crystals form inside and around the joints, while hyperuricaemia occurs when an unusually high level of uric acid is found in the blood. Both conditions are linked to unhealthy lifestyles.
The difference in absolute gout risk between those receiving surgery and those undergoing usual care was shown to be three percentage points at 15 years, with the number of subjects needing to be treated by bariatric surgery to prevent one incident gout event calculated at 32.
During follow-up, the surgery group also had a lower incidence of hyperuricaemia, showing the broad-ranging health benefits this type of surgery can deliver for people with obesity.
