Scoping review maps evidence on chronodisruption affecting weight outcomes in post-bariatric surgery, suggesting potential implications for recovery.
This scoping review maps evidence on whether chronodisruption—defined as disturbances in sleep duration, sleep quality, sleep timing, chronotype, social jetlag (SJL), meal timing/chrononutrition, shift work, and light at night (LAN)—is associated with post-metabolic and bariatric surgery (MBS) weight outcomes (percent excess weight loss [%EWL], percent total weight loss [%TWL], body mass index [BMI] change, insufficient weight loss, and weight gain [recurrent weight gain (RWG), also termed weight regain (WR)]). Procedures include but are not limited to Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and one-anastomosis gastric bypass (OAGB).
