Gastric bypass surgery lowers blood pressure

Previous studies have shown that obesity surgery reduces blood pressure in the first few years after surgery. As part of the ongoing Swedish Obesity Subjects (SOS) study led by researcher Lena Carlsson at Wallenberg Laboratory, the patients were divided according to the type of obesity surgery they received. A clear long-term effect on blood pressure was only observed in patients who underwent gastric bypass surgery and not gastric banding. This difference may be explained by the diuretic effect of gastric bypass surgery.
