Obese people who have weight loss surgeries like gastric bypass are much less likely than those who don’t have surgery to develop gout, a painful type of arthritis, according to a Swedish study.
People who chose to get weight loss surgery are also less than half as likely to develop hyperuricemia, too much uric acid in urine, which can be a precursor to gout, the study team writes in the Annals of the Rheumatic Diseases.
Gout is an intensely painful condition involving tender joints and redness that is caused by a build-up of uric acid in joints.
Gout affects nearly 4 percent of people in the United States and is on the rise, according to the Centers for Disease Control and Prevention.”
Obesity is extremely common in western and developing countries and it comes with a burden of associated diseases, such as gout itself,” said lead author Dr. Cristina Maglio of the University of Gothenburg in Sweden.
“Bariatric surgery is the only obesity treatment that is effective in reducing body weight up to many years after the surgery,” Maglio said by email.
To explore the link between gastric surgeries and gout, the study team used data from a Swedish study on nearly 4,000 middle-aged, obese participants recruited between 1987 and 2001 from healthcare centers across Sweden.
Half of the patients chose to undergo bariatric surgeries including gastric bypass, gastric banding and stomach stapling, while the other half of patients received no surgery and acted as a comparison group.
