Key result
Bariatric surgery linked to ~27% maximal weight loss and long-term reductions in obesity-related comorbidities.
Why the study?
Long-term weight and comorbidity outcomes following bariatric surgery at a publicly funded obesity service required assessment.
Does bariatric surgery reduce weight and obesity-related comorbidities in individuals at a publicly funded obesity service?

No
Does bariatric surgery reduce weight and obesity-related comorbidities in individuals at a publicly funded obesity service?
Bariatric surgery in a publicly funded service demonstrates long-term efficacy with sustained weight loss up to 10 years and significant reductions in major obesity-related cardiometabolic comorbidities at 5 years.
May inform shared decision-making for bariatric surgery; leaves open confirmation in randomized trials for cardiovascular outcomes.

Lee et al. (2026) conducted a cohort in Obesity (n=203). Bariatric surgery vs. Baseline was evaluated on Percentage change in weight over time and change in prevalence of obesity-related comorbidities. Bariatric surgery resulted in a maximal mean weight reduction of 26.6% at 18 months, with weight loss maintained up to 10 years and significant reductions in major obesity-related comorbidities.
