The enteric nervous system directly controls the gut motility, whereas the extrinsic nerve pathways influence gut contractility indirectly through modifying this enteric innervation. [3] In almost all cases of neurogenic bowel dysfunction it is the extrinsic nervous supply affected and the enteric nervous supply remains intact.
Autoimmune gastrointestinal dysmotility (AGID) is an autoimmune disease autonomic neuropathy affecting the gastrointestinal organs and digestive system of the body. Dysmotility is when the strength or coordination of the esophagus, stomach or intestines muscles do not work as they should. [1]
Abnormal motility Studies have shown altered muscle contractility and tone, bowel compliance, and transit may contribute to many of the gastrointestinal symptoms of FGID which may include diarrhea, constipation, and vomiting. [20] Visceral hypersensitivity In FGID there is poor association of pain with GI motility in many functional GI disorders.
Gastrointestinal motility disorders occur when the digestive tract, especially its muscles or nerves, malfunctions. They are sometimes treated by physicians with subspecialty training in neurogastroenterology.
Treatment targets nutritional support, improving intestinal motility, and minimizing surgical intervention. [4] Bacterial overgrowth of the small intestine can occur in chronic cases – presenting as malabsorption , diarrhea, and nutrient deficiencies [ 12 ] – which may require the use of antibiotics.
Constipation is a bowel dysfunction that makes bowel movements infrequent or hard to pass. [2] The stool is often hard and dry. [4] Other symptoms may include abdominal pain, bloating, and feeling as if one has not completely passed the bowel movement. [3]
Antroduodenal manometry aids in differentiating between myopathic (scleroderma, amyloidosis) and neuropathic (diabetes mellitus) causes of impaired motility. The test shows a decreased frequency and amplitude of migrating motor complexes in patients with a myopathic condition. The migrating motor complexes in patients whose disease has a ...
Intestinal failure is decreased intestinal function such that nutrients, water, and electrolytes are not sufficiently absorbed. Short bowel syndrome is when there is less than 2 m (6.6 ft) of working bowel and is the most common cause of intestinal failure. [3]
