A well studied model is celiac disease, in which increased intestinal permeability appears secondary to the abnormal immune reaction induced by gluten and allows fragments of gliadin protein to get past the intestinal epithelium, triggering an immune response at the intestinal submucosa level that leads to diverse gastrointestinal or extra ...
[150] [152] Probiotics have positive effects such as enhancing the intestinal mucosal barrier, providing a physical barrier, bacteriocin production (resulting in reduced numbers of pathogenic and gas-producing bacteria), reducing intestinal permeability and bacterial translocation, and regulating the immune system both locally and systemically ...
Psychophysiological factors may affect the expression of these genes, thus leading to symptoms production associated with FGID. [10] Sociocultural factors and family interactions have been shown to shape later reporting of symptoms, the development of FGIDs, and health care seeking. The expression of pain varies across cultures as well ...
Intestinal permeability is a measurement of intestinal mucosal barrier function and is defined as "the facility with which intestinal epithelium allows molecules to pass through by non-mediated passive diffusion." [11] Permeability in this respect is mostly related to the measurable passage of ions and small inert molecules. Standard methods ...
The signs and symptoms of protein losing enteropathy include diarrhea, fever, and general abdominal discomfort. [4] Swelling of the legs due to peripheral edema can also occur; however, if the PLE is related to a systemic disease such as congestive heart failure or constrictive pericarditis, then these symptoms could be due directly to the underlying illness.

The symptoms of bacterial overgrowth include nausea, flatus, [5] constipation, [6] bloating, abdominal distension, abdominal pain or discomfort, diarrhea, [7] fatigue, and weakness. SIBO also causes an increased permeability of the small intestine. [8] Some patients may lose weight.
Carbohydrate digestion and transport is impaired in individuals with autism spectrum disorder, which is thought to be attributed to functional disturbances that cause increased intestinal permeability, deficient enzyme activity of disaccharides, increased secretin-induced pancreatico-biliary secretion, and abnormal fecal flora Clostridia taxa.

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.
