GASTROINTESTINAL DISEASES, DELAYED GASTRIC EMPTYING, PURGING
Delayed gastric emptying has been observed in numerous gastrointestinal diseases marked by increased postprandial fullness, nausea, and stomach discomfort (Hajishafiee, Bitarafan, & Feinle-Bisset, The current study examined gastric emptying in women with PD and BN who used vomiting as their primary purging method, women with nonpurging BN, and non-eating disorder controls to determine whether (i) gastric emptying is linked to binge eating, purging, or both, (ii) gastric emptying is associated with postprandial gastrointestinal distress, and (iii) a medication that increases gastric motility impacts differences in gastric emptying and postprandial gastrointestinal distress. Data from participants in the current study were included in prior analyses to examine whether postprandial peptide YY (PYY) and ghrelin responses contributed to differences in subjective responses to a fixed test meal (Keel et al.,
