Bariatric surgery: the fall of a unnecessary technique?

"Patients undergoing bariatric surgery have an increased risk for self-harm emergencies after the surgery. These adverse events undermine the overall benefits of bariatric surgery. The study findings could be useful for bariatric surgeons and emergency physicians in postoperative follow-up. Additional clinical implications include active postoperative screening for self-harm risk among patients who have undergone bariatric surgery and are presenting for follow up. Patient and surgery factors could help identify vulnerable patients. Overall, these findings imply that more work is needed to understand why self-harm behaviors increase in the postoperative period and how these risks might be reduced."
