Impact of Bariatric Surgery on Medication Costs and Disease Burden in Obesity: A Retrospective Cohort Study.
Article in Obesity surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionObesity is a highly prevalent chronic disease associated with substantial morbidity, multiple comorbidities, and a significant burden on healthcare systems. Metabolic bariatric surgery (MBS) is effective in achieving weight loss and improving obesity-related comorbidities, potentially reducing pharmacotherapy requirements and overall disease burden. Nevertheless, evidence from Portuguese real-world clinical practice remains limited. Therefore, this study aimed to provide the first Portuguese evaluation of the impact of MBS on pharmacotherapy-related healthcare costs and on the prevalence and burden of obesity-associated comorbidities.
methodsA retrospective cohort study was conducted. Annual pharmacotherapy costs and changes in the prevalence and burden of obesity-associated comorbidities, measured using Years Lived with Disability (YLD), were compared before and 3 years after surgery.
resultsThree years after MBS, the mean annual pharmacotherapy cost per patient decreased by €56.11 (p < 0.05). Reductions in medication costs were observed for antihypertensive, lipid-lowering, and antidiabetic therapies (all p < 0.05). The prevalence of obesity-related comorbidities also decreased, particularly hypertension, type 2 diabetes mellitus, dyslipidemia and asthma (all p < 0.05). Correspondingly, the estimated burden of disease decreased, with mean YLD declining from 0.022 before surgery to 0.014 3 years after surgery (p < 0.05).
conclusionOver 3 years of follow-up, MBS was associated with reductions in medication costs, the prevalence of obesity-related comorbidities, and overall disease burden. These findings highlight the clinical and economic benefits of MBS in the management of obesity and its associated conditions over the medium term.
