Brief Summary: Insights into the pathophysiology of functional dyspepsia, with recent demonstration of inflammation with eosinophilia and mastocytosis in the duodenum (3, 6, 7), providing a possible lead toward reduced secretion of a potential mediator of post-prandial gastric accommodation, the gastrointestinal peptide hormone secretin. The dominant site of synthesis and secretion of this hormone are enteroendocrine S cells in the duodenum. Inflammation-induced damage to these cells could produce a deficiency. Since intraluminal acid is a prominent stimulant of S cell secretion, the attempts to treat functional dyspepsia with anti-secretory medications could actually exacerbate a secretin deficiency syndrome. This raises the possibility of the therapeutic use of a secretin agonist or a positive allosteric modulator of the secretin receptor for patients with functional dyspepsia.
Detailed Description: The investigators will utilize single photon emission computed tomography (SPECT) methodology and gamma scintigraphy present in the GI laboratory of the outpatient Clinical Research Unit to study fasting gastric volumes and postprandial gastric accommodation responses and gastric emptying rates of a standardized meal in patients with functional dyspepsia and healthy subjects. Both groups will be studied twice, using crossover design, once with administration of secretin and once with placebo.
