Preoperative and post-operative intensive interventions improved symptoms of depression and anxiety , quality of life , diastolic blood pressure , and resting heart rate but not lipids or glycaemic measures .
This systematic review and meta- analysis of intervention studies aims to evaluate the effect of preoperative and /or post-operative support for adults who elect bariatric surgery delivered by a multidisciplinary team ( MDT )  on post-operative body composition , mental health , co-morbidities , quality of life , and side effects .
Long-term Weight Regain after Gastric Bypass: A 5-year Prospective Study
Background A certain weight gain occurs after obesity surgery compared to the lower weight usually observed between 18 and 24 months postsurgery . The objective of this study was to evaluate weight regain in patients su bmi tted to gastric bypass  over a 5-year follow-up period . Material s and Methods A longitudinal prospect i ve study was conducted on 782 obese patients of both genders . Only patients with at least 2 years of surgery were included . The percentage of excess body mass index ( BMI ) loss at 24 , 36 , 48 , and 60 months postsurgery was compared to the measurements obtained at 18 months after surgery . Surgical therapeutic failure was also evaluated . Results Percent excess BMI loss was significant up to 18 months postsurgery ( p < 0.001 ) , with a mean difference in BMI of 1.06 kg/m2 compared to 12 months postsurgery . Percent BMI loss was no longer significant after 24 months , and weight regain became significant within 48 months after surgery ( p < 0.01 ) . Among the patients who presented weight regain , a mean 8 % increase was observed within 60 months compared to the lowest weight obtained at 18 months after surgery . The percentage of surgical failure was higher in the superobese group at all times studied , reaching 18.8 % at 48 months after surgery . Conclusion Weight regain was observed within 24 months after surgery in approximately 50 % of patients . Both weight regain and surgical failure were higher in the superobese group . Studies in regard to metabolic and hormonal mechanisms underlying weight regain might eluci date the causes of this finding
