ABSTRACT:
Inflammatory bowel diseases (IBD) termed as chronic inflammatory disorders of the gastrointestinal tract distinct by episodes of reversion and decline. The two identified subtypes of the disease, ulcerative colitis and Crohn's Disease which differ in forms of clinical presentation. Environmental factors, including infections, diet, lifestyle factors, medication use have contributed to alterations in the global prevalence of the disease. Although the exact pathogenesis of IBD remains unknown, part of the underlying mechanism is a deregulated host immune response to intestinal flora, in genetically vulnerable Beings. The incidence of IBD is persistently rising in other earlier low incidence areas, such as Asia and the developing world. The annual frequency of CD is highest in North America (20.2 per 100,000, per person-years); whereas the annual occurrence of UC is highest in Europe (24.3 per 100,000 per person-years) Environmental risk factors of IBD is smoking, air water pollution, vitamin D, dietary, NSAID, stress. The newly described Th17 cells are also involved in the gut inflammatory answer in IBD. To understand the pathogenesis of IBD alternative model has been used such as zebrafish, c. elegans, Drosophila. The novel treatment of IBD such as vedolizumab, Etrolizumab, agents targeting specific pathways in IBD, but unfortunately possess life-threatening adverse effect and globally increased cost. This review also focuses on the favourable results from the use of herbal products in the treatment of IBD.
