BACKGROUND Online weight-loss communities (OWCs) have been becoming increasingly popular for weight management, which enable individuals to monitor (i.e. self-monitoring) and discuss (i.e. social interaction) their weight-loss experiences. However, there has been limited understanding of the role of individuals’ prior weight-loss experiences in subsequent weight-loss success, especially in online settings. OBJECTIVE To address the significant literature gap, this study investigates the relationship between prior weight-loss experiences (success or failure), online social support and subsequent weight-loss success in the contexts of OWCs based on self-determination theory. METHODS The data of 1650 users from one popular OWC is collected using a python crawler procedure, including individuals’ characteristics (e.g. gender, age, friends, posts, membership duration) and weight-loss diary information. Two logit regression models are deployed to estimate the effects of prior weight-loss experiences and social support on subsequent weight-loss success, as well as the moderation effect of social support. RESULTS The results reveal that prior successful weight-loss experiences are positively related to subsequent weight-loss success (β=0.376,p<0.01) while the relationship between prior failed weight-loss experiences and subsequent weight-loss success is negative (β=-0.225,p<0.05). Meanwhile, online social support can not only influence positively subsequent weight-loss success directly (β=0.441,p<0.01) but also undermine the negative effect of prior failed weight-loss experiences (β=0.025,p<). Nevertheless, social support has no significant moderating effect on the relationship between prior successful weight-loss experiences and subsequent weight-loss success (β=0.104,p>0.1). CONCLUSIONS This study contributes to literature on prior experiences and online social support in the context of OWCs, and provides valuable insights for OWCs’ designs to improve users’ engagement and their weight-loss success.

The annual volume of bariatric surgery is growing, giving rise to an increase in complications requiring complex management, including revision. Bariatric revision procedures are also becoming increasingly necessary for weight-loss recidivism and patients at the extreme of obesity. This chapter outlines clinical management pathways used to address secondary bariatric surgery. It summarizes reasons for, and outcomes with, revision of a laparoscopic gastric band, vertical banded gastroplasty, sleeve gastrectomy, or Roux-en-Y gastric bypass. Surgical techniques used to manage weight regain or failed weight loss after bariatric surgery are also discussed. Finally, surgical solutions for bariatric surgery-induced malnutrition are described, particularly in the setting of biliopancreatic diversion, duodenal switch, or jejunoileal bypass. Overall, the chapter concludes that standardization of revisional procedures can have a significant patient impact, and guidelines must be evidence-based in order to ensure patient safety and success.
