We aimed to estimate the association of glucagon-like peptide 1 (GLP-1) receptor agonist therapy with the incidence of endoscopically visible gastric contents after preprocedural fasting. ⋯ In fasting patients, GLP-1 agonist therapy was associated with an increased incidence of residual gastric contents, potentially posing an additional risk of periprocedural pulmonary aspiration.
