[1] The small intestine expands rapidly due to the presence of hypertonic/hyperosmolar contents from the stomach
In response to gastric balloon distension during fasting and following meal intake, patients with functional dyspepsia demonstrate impaired proximal stomach accommodation. [ 24 ] [ 25 ] Due to the poor accommodation, there is a disproportional volume distribution, with the fundus volume being less and the antral volume being bigger than usual ...

It is composed of a specific family of glycoproteins termed mucins and is generally very viscous. Mucus is made by two types of specialized cells termed mucous cells in the stomach and goblet cells in the intestines. Signals for ...
Activation of a wide range of serotonin receptors by serotonin itself or by certain prokinetic drugs results in enhanced gastrointestinal motility. [ 3 ] Other prokinetic drugs may increase acetylcholine concentrations by stimulating the M 1 receptor which causes acetylcholine release, or by inhibiting the enzyme acetylcholinesterase which ...

[99] Medications such as loperamide (Imodium) and bismuth subsalicylate may be beneficial; however they may be contraindicated in certain situations. [100]
