[Functional disorders of the gastrointestinal tract in the context of morphofunctional unity]
Abstract:
The aim of this work was systematization of the currently available data on pathological physiology and morphology of functional disorders of the gastrointestinal tract (GIT) underlain by combined changes of neuroendocrine and neural regulation related to genetic polymorphism and external provoking factors (in the first place, stress). Altered function and morphology of diffuse neuroendocrine system and expression of certain regulatory molecules (nitric oxide, interleukin-1) in the patients with functional GIT disorders induce inflammation and changes in epitheliocyte regeneration, i.e. morphological substrate of the disease. Verification of various morphofunctional and structural changes accompanying functional pathology of GIT necessitates further improvement of classification criteria for functional diseases as reflected in the forthcoming Rome criteria IV.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
