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.
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.
The enteric nervous system is highly sophisticated and can govern almost all gastrointestinal activities, including motility, independently of the central and peripheral neurological systems. [19] [5] Enteric neuropathies may share pathogenetic processes with central nervous system neurodegenerative illnesses due to their close similarities. [19]
Parkinson's disease [21] - related to the neurodegeneration of gastrointestinal tract; Autoimmune conditions — conditions including systemic lupus erythematosus and scleroderma lead to collagen vascular deposition [22] and gastrointestinal motility disruption; Mitochondrial disease [23] - IPO is a known presentation for mitochondrial disease
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.
Functional abdominal pain syndrome is a functional gastrointestinal disorder. [4] Functional gastrointestinal disorders (FGD) are common medical conditions characterized by recurrent and persistent gastrointestinal symptoms caused by improper functioning of the enteric system in the absence of any identifiable organic or structural pathology, such as ulcers, inflammation, tumors or masses.
Channelopathy and muscular dystrophy: IBS and functional GI diseases are comorbidities of genetic channelopathies that cause cardiac conduction defects and neuromuscular dysfunction, and result also in alterations in GI motility, secretion, and sensation. [92] Similarly, IBS and FBD are highly prevalent in myotonic muscle dystrophies. Digestive ...
GI peptides are signal molecules that are released into the blood by the GI cells themselves. They act on a variety of tissues including the brain, digestive accessory organs, and the GI tract. The effects range from excitatory or inhibitory effects on motility and secretion to feelings of satiety or hunger when acting on the brain.
