  • Description: Background: Satiety, defined as the duration of the sensation of fullness, is usually measured by validated visual analog scales (VAS) for appetite. Gastric function plays a key role in food intake regulation. However, the association between gastric emptying (GE) and VAS-appetite is unknown. Methods: In this cross-sectional study, 134 participants [age = 39 ± 0.8 years, BMI = 38 ± 0.5 kg/m2, 67% females] completed simultaneous measurements of GE and VAS-appetite. After a 320kcal meal, GE was measured by scintigraphy and appetite by validated 100mm VAS for 240 min. Then, in the same day, satiation, defined as calories consumed to terminate meal, and measured by ad libitum meal. Percent of meal retention in the stomach, VAS area under curve (AUC0-240min), and overall appetite score (OAS) were calculated. Pearson correlation (p) determined the association of GE with VAS-appetite and satiation. Appetite components were also analyzed by quartiles based on GE120min. Results: GE120min was correlated with sensation of VAS-hungerAUC(0-240min) (P = °.24, p = °.004), fullnessAUC(0-240min) (P = °.16, p = 0.05), and OASAUC(0-240min) (p = 0.20, p = 0.02). Patients with rapid GE120min had a mean increase in VAS-hungerAUC(0-240min) by 32 mm/min (15.62%, p = 0.03) compared to normal/slow GE120min. GE120min and VAS-OAS120min were negatively correlated with calories consumed in the ad libitum meal (p = -0.32 p = 0.002; and (p = -0.38, p < 0.0001, respectively). Conclusions: GE is associated with the sensations of appetite, and rapid GE is associated with increased appetite, which may contribute to weight gain.
