Influence of Weight Loss on Obesity-Associated Complications After Metabolic and Bariatric Surgery in Adolescents

Obesity (Silver Spring). 2020 Dec;28(12):2397-2404. doi: 10.1002/oby.23038.


Objective: Following metabolic and bariatric surgery (MBS), most adolescents experience weight loss and improvement of many obesity-associated complications (OACs). The relationship between weight loss and remission of OACs after MBS in adolescents has not been well described.

Methods: The Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS) is a multi-institutional prospective observational study of adolescents who underwent MBS between 2007 and 2012. Lower-weight-loss responders (LWLRs) were defined as having <20% total body weight loss (TBWL) and higher-weight-loss responders (HWLRs) were defined as having ≥20% TBWL at 5 years after MBS. The prevalence of OACs was compared at baseline and 5 years after MBS.

Results: Both LWLRs (n = 114) and HWLRs (n = 78) lost significant weight within the first year following MBS; however, the TBWL at 5 years for the LWLRs was 8.6% ± 9.5% compared with 33.8% ± 9.2% for the HWLRs. Those in the HWLR group were more likely to experience durable remission of composite dyslipidemia at 5 years, whereas there were no differences between groups in remission rates of all other OACs.

Conclusions: Greater weight loss after MBS in adolescents was associated with greater remission of composite dyslipidemia; however, remission of other OACs was not dependent on major sustained weight loss.
