Gastric nerve connections to the spinal cord and brain medulla oblongata, which regulate the movements of the stomach. The cranium dysfunction mechanical changes in the gut can compress the vagus nerve at any number of locations along the vagus, slowing the heart. As the heart slows, autonomic reflexes are triggered to increase blood pressure ...
This may be linked to delayed small bowel and colon transit. [32] If symptoms are refractory (especially in the setting of weight loss), or if an intestinal neuromyopathic disorder is suspected, then motility may be evaluated via antroduodenal manometry, wireless motility capsules, whole gut scintigraphy, or radiopaque markers.

The vagus nerve is also responsible for regulating inflammation in the body, via the inflammatory reflex. [7] Efferent vagus nerve fibers innervating the pharynx and back of the throat are responsible for the gag reflex. In addition, 5-HT 3 receptor-mediated afferent vagus stimulation in the gut due to gastroenteritis is a cause of vomiting. [8]
“The vagus nerve is the main motor nerve in the GI tract, so it controls motility, but it’s also a sensory nerve so it can affect pain,” says Dr. Thomas Abell, a professor of ...
Vagal tone is activity of the vagus nerve (the 10th cranial nerve) and a fundamental component of the parasympathetic branch of the autonomic nervous system. This branch of the nervous system is not under conscious control and is largely responsible for the regulation of several body compartments at rest.
Functional gastrointestinal disorders (FGID), also known as disorders of gut–brain interaction, include a number of separate idiopathic disorders which affect different parts of the gastrointestinal tract and involve visceral hypersensitivity and motility disturbances.
"The gut and brain utilize a two-way communication so the perceived threat can impact the gut and gut pain can impact the brain." Eliminating stress isn't possible, but Moore says we can manage it.
AGID is diagnosed with a complete medical history, exam of patients motility and with special blood tests looking for autoantibodies consistent with neurologic autoimmunity. [2]
