Bypass Surgery Linked to Significant Weight Loss, Increased BNP

Gastric bypass surgery has been linked to significant excess weight loss and increased B-type natriuretic peptide concentrations, according to a study in Surgical Endoscopy.


Researchers said the link between BNP increase with weight loss suggests a new mechanism for surgically induced weight loss.


The study measured plasma volume, weight and BNP preoperatively and postoperatively at three, six and 12 months for 101 patients undergoing laparoscopic gastric bypass surgery by one surgeon. Outcomes were compared by matched t-test.
