Why the study?
The study aimed to investigate the heterogeneity of weight loss 5 years after Roux-en-Y gastric bypass, its association with cardiometabolic health, and prediction estimates of surgical treatment failure.
Population
Patients undergoing Roux-en-Y gastric bypass across 29 surgical units in Sweden
Comparison
Surgical treatment failure vs successful weight loss
Design
Retrospective analysis of prospectively collected registry data

Insufficient weight loss post-RYGB signals higher cardiometabolic risk; hypothesis-generating for prediction models and targeted interventions.
Surgical treatment failure 5 years after Roux-en-Y gastric bypass occurs in nearly a quarter of patients and is strongly associated with increased risks of type 2 diabetes, dyslipidemia, and hypertension.
Brissman et al. (2021) studied this question.
