By Madeline Kennedy (Reuters Health) – 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.
