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.
[Auto, unreviewed; quoted from abstract conclusions] We observed that 80% of adolescents on GLP1-RAs had solids on gastric ultrasound despite having fasted for over 12 h.

Abstract
[BACKGROUND] Glucagon-like peptide-1 receptor agonists (GLP1-RAs) are approved in patients aged ≥10 yr for type 2 diabetes mellitus and aged ≥12 yr for obesity. We examined the effect of GLP1-RAs on the retention of gastric contents in fasting adolescents. [METHODS] This prospective cohort study examined adolescent patients (10-18 yr) at a single institution between June 2023 and November 2024. Three groups were compared: a GLP1-RA group; a group at-risk for delayed gastric emptying not on GLP1-RAs; and a healthy control group. All patients fasted 8 h for solids and 1 h for clears liquid. Gastric contents were examined utilising gastric ultrasound qualitatively on a 3-point scale, and quantitatively. The primary outcome was the number of adolescents on GLP1-RAs with residual gastric contents (presence of solids or gastric fluid volume ≥1.5 ml kg-1). [RESULTS] In total, 67 patients were analysed: 20 in the GLP1-RA group; 27 in the at-risk group; and 20 in the control group. The median age was 14.8 (interquartile range [IQR] 13.2-16.6) yr, and median fasting durations for solids and clears were 13 h (IQR 12-14) and 12 h (IQR 3.5-13), respectively. In the GLP1-RA group, 16/20 patients (80%) had solids present on gastric ultrasound, compared with 17/27 patients (63%) in the at-risk group and 1/20 patient (5%) in the control group (unadjusted P <0.001; adjusted P <0.02, with propensity score adjustment for age, body mass index, sex, race, and NPO time). [CONCLUSIONS] We observed that 80% of adolescents on GLP1-RAs had solids on gastric ultrasound despite having fasted for over 12 h.
