Impact of Preoperative Semaglutide Discontinuation Timing on Postoperative Outcomes in Aesthetic Abdominoplasty: A Retrospective Comparative Study.
Article in Aesthetic plastic 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
backgroundThe widespread adoption of GLP-1 receptor agonists such as semaglutide for weight loss has led to an increasing number of non-diabetic patients seeking body contouring procedures after pharmacologic weight reduction. However, concerns have emerged regarding postoperative complications potentially linked to GLP-1 therapy, particularly when continued up to the time of surgery.
objectivesThis retrospective cohort study aimed to evaluate the impact of preoperative semaglutide discontinuation timing on short-term postoperative outcomes in aesthetic lipoabdominoplasty.
methodsEighty patients who underwent primary lipoabdominoplasty were divided into four groups: continued semaglutide until surgery (Group A), 2-week discontinuation (Group B), 4-week discontinuation (Group C), and semaglutide-naïve controls (Group D). All patients were matched for age, BMI, and surgical technique. Postoperative complications within 30 days were assessed.
resultsGroup A exhibited the highest complication rate (45%), including wound dehiscence, infection, and seroma formation. Group B showed moderate improvement (30% complication rate), while Group C demonstrated a significant reduction in adverse outcomes (10%), comparable to the control group (10%). Gastrointestinal intolerance and prolonged drain duration were also more frequent in patients with ongoing semaglutide use. No reoperations or readmissions occurred.
conclusionsContinuation of semaglutide until surgery significantly increases postoperative complication risk in lipoabdominoplasty. A 4-week preoperative discontinuation period effectively normalizes outcomes, supporting its use as a safety measure in aesthetic surgery candidates. These findings emphasize the need for standardized perioperative management protocols for patients on GLP-1 therapy and underscore the importance of interdisciplinary coordination and nutritional assessment.
