UK adults who have overweight or obesity retain their weight over time, which is associated with an increased risk of health complications and death, according to a study published in the open access journal BMC Public Health. Researchers at the University of Nottingham investigated the development of body mass index (BMI) over time.

Pre-operative opioid use was an independent risk factor for severe complications as well as prolonged length of stay, readmission and reoperation after primary bariatric surgery, according to a study that included more than 56,000 patients.
