Impact of GLP-1 Agonists on Post-Operative Outcomes in Aesthetic & Body Contouring Surgery: A Systematic Review & Meta-Analysis

Population unclearUNKNOWN: the abstract does not report age, BMI or diabetes status for the 29,357 pooled surgical patients.
Could weight loss explain it?
PossiblyPossibly: the abstract does not examine whether weight loss, reduced intake or nutritional status explains the wound-healing findings, so they are not separated from a drug effect.

Study facts come from the paper. Population match, weight-loss explanation and study tier are our judgments, made against the reference group of healthy normal-weight adults aged 55–75.

This systematic review and meta-analysis pooled twelve studies (29,357 patients) of people having aesthetic or body-contouring surgery with and without GLP-1 receptor agonist exposure. In the pooled observational analyses, GLP-1 drug use was linked to more delayed wound healing and hypertrophic scarring, while seroma was less common than in people who had earlier had bariatric surgery. The abstract gives no effect sizes and no results for infection, wound breakdown, haematoma or blood clots, and these associations do not show cause.

Adverse events
Higher risk of delayed wound healing and hypertrophic scarring with GLP-1 RA exposure; lower seroma rates than in patients with prior bariatric surgery
Limitations
Pools observational analyses only; the abstract gives no effect sizes, patient characteristics or reason for GLP-1 RA use, and the authors call for prospective studies.

Abstract

[BACKGROUND] Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have rapidly expanded in use for weight loss, resulting in a growing population of patients presenting for aesthetic and body-contouring procedures. Despite their increasing prevalence, the effects of GLP-1 RAs on postoperative wound healing and surgical outcomes remain poorly defined. [METHODS] A systematic review and meta-analysis were conducted in accordance with PRISMA guidelines. PubMed, Embase, and Cochrane CENTRAL were searched from database inception through May 2026. Studies comparing postoperative outcomes in patients undergoing aesthetic and/or body-contouring surgery with and without GLP-1 RA exposure were included. Primary outcomes included infection, wound dehiscence, delayed wound healing, hypertrophic scarring, seroma, hematoma, and venous thromboembolism (VTE). Random-effects meta-analyses were performed using risk ratios (RRs) with 95% confidence intervals (CIs). [RESULTS] Twelve studies comprising 29,357 patients met inclusion criteria, with 10 studies included in quantitative synthesis. In pooled observational analyses, GLP-1 RA exposure was associated with increased risk of delayed wound healing and hypertrophic scarring. Subgroup analysis comparing GLP-1 RA users with patients who had previously undergone bariatric surgery demonstrated decreased seroma rates in the GLP-1 RA group. [CONCLUSIONS] GLP-1 RA use in patients undergoing aesthetic and body-contouring surgery was associated in pooled observational analyses with increased risks of delayed wound healing and hypertrophic scarring, while GLP-1 RA use was associated with lower seroma rates in comparison with patients who have undergone bariatric surgery. As GLP-1 RA use become increasingly prevalent, further prospective studies are needed to clarify their perioperative effects and optimize patient selection and surgical outcomes.
