Objectives: To clarify 1) whether gastric emptying of a mixed meal is delayed in patients with gastroesophageal reflux and 2) the relationship between dyspeptic symptoms and delayed gastric emptying in refluxers.
Methods: Gastric emptying of a solid meal was studied by ultrasound in 25 patients with pathological esophageal acid exposure. Gastric emptying was then assessed in relation to upper digestive endoscopy, esophageal manometry, 24-h pH monitoring and quantification of symptoms of reflux- and dysmotility-like dyspepsia.
Results: Fifteen of 25 refluxers had esophagitis, and 15 were "dyspeptic". Refluxers exhibited a significant delay in gastric emptying compared with controls [307.6 (21.0) vs. 209 (10.4) min, p < 0.001). Patients with delayed emptying had low LES pressure [11.9 (2.1) vs. 18.6 (2.1) mm Hg, p < 0.05]. There was no correlation between delayed emptying and either pH monitoring or presence of esophagitis. There were no differences in any of the pH monitoring parameters between refluxers with and without coexisting dysmotility-like symptoms.
Conclusions: Gastric emptying of a solid meal is markedly delayed in patients with gastroesophageal reflux. However, no direct causal link was found between delayed emptying and reflux. Our data suggest the presence of a motility disorder in gastroesophageal reflux which is not confined to the esophagogastric junction.

Type 2 diabetes mellitus (T2DM) and obesity are critical global health issues with rising incidence rates. Glucagon-like peptide-1 (GLP-1) analogues have emerged as effective treatments due to their ability to regulate blood glucose levels and gastric emptying through central nervous signals involving hypothalamic receptors, such as leptin. To address the short plasma half-life of native GLP-1, a C-16 fatty acid was conjugated to lysine in the GLP-1 analogue sequence to enhance its longevity.

Obesity significantly influences drug pharmacokinetics (PK), which challenges optimal dosing. This study examines the effects of diet-and-exercise-induced weight loss on key drug-metabolizing enzymes and gastric emptying in patients with obesity, who frequently require medications for comorbidities. Participants followed a structured weight management program promoting weight loss over 3-6 months and were not concomitantly on potential CYP inducers or inhibitors.

The nutritive value of a protein is determined not only by its amino acid composition, but also by its digestibility in the gastrointestinal tract. The interaction between proteins and pepsin in the gastric stage is the first step and plays an important role in protein hydrolysis. Moreover, it affects the amino acid release rates and the allergenicity of the proteins.

Background: Glucagon-like peptide-1 receptor agonist (GLP-1RA) therapies are increasingly used for the treatment of type 2 diabetes mellitus and obesity. Despite growing awareness of potentially increased risk of pulmonary aspiration due to delayed gastric emptying, the risks and benefits of their perioperative use in patients undergoing cardiac procedures remains unexplored. A scoping review was performed to investigate the perioperative GLP-1RA use in patients undergoing cardiac procedures and recommendations.

Background And Aims: Glucagon-like peptide-1 receptor agonists (GLP1RAs) can cause delayed gastric emptying, raising concern for retained gastric contents (RGCs) during endoscopy and adverse anesthesia events. We aimed to determine associations between GLP1RA and endoscopy and anesthesia outcomes.
Methods: This single-center retrospective cohort study examined patients prescribed GLP1RA who underwent outpatient endoscopy stratified by exposure at the time of endoscopy.
