Functional Gastrointestinal Disorders

Functional Gastrointestinal Disorders

Functional GI DisorderFunctional gastrointestinal disorders consist of a collection of symptoms attributed to the gastrointestinal tract that can range from esophagus to rectum.  These symptoms develop from abnormalities in gastrointestinal motility, increased nerve sensitivity of the intestinal tract or dysregulation of the brain-gut nerve pathways.  Symptoms produced can be any combination of: nausea, vomiting, heartburm chest, abdominal or rectal pain or discomfort, diarrhea, or constipation.  When these symptoms persist for at least 3 months and meet certain criteria (Rome III), and radiological or endoscopic studies are negative, they are considered to fulfill criteria for  a functional GI disorder (FGID).  FGIDs are defined by symptoms and abnormal motility may or may not be present.

A motility disorder is an abnormlity in the coordination of the muscles of the gastrointestinal tract.  When the normal functioning is impaired there may increased or decreased motility and this can also produce pain.  Examples would be gastroparesis (impaired and slowed emptying of the stomach), pseudo-obstruction (slowing of the intestines), or abnormal emptying of the rectum (dyssynergic defecation) .  Motility disorders are defined by impairment of the muscular system of the gastrointestinal tract and there may or may not be symptoms.
