Predictors of Preoperative Weight Loss in Morbidly Obese Adults Waiting for Bariatric Surgery: A Prospective Cohort Study

Background Preoperative weight loss is encouraged before bariatric surgery, as it is associated with improved surgical conditions. It has also been related to better postoperative outcomes, but this relationship is less clear. However, little is known about what predicts weight loss preoperatively, so the aim was to identify psychosocial and clinical predictors of preoperative weight loss.
