The human gut microbiota has become the subject of researches in recent years and our knowledge of the resident species and their potential functional capacity is rapidly growing. Our gut harbors a complex community of over 100 trillion microbial cells. Therefore, our gut microbiota evolves with us and plays a pivotal role in human health and disease. This has clear effects on physiologic, immunologic, and metabolic processes in human health, aberrations in the gut microbiome and intestinal homeostasis have the capacity for multisystem effects. Changes in microbial composition are implicated in the increasing for a broad range of inflammatory diseases, such as allergic disease, asthma, inflammatory bowel disease (IBD), obesity, and associated …show more content…

Indeed, the many instances of such potential associations are too great to summarize in this review and thus here the focus is on associations that have been the focus of greatest attention, that is, the possibility of a link between the gut microbiota and chronic GI diseases, including irritable bowel syndrome (IBS): Functional bowel disorders such as IBS are defined solely on symptom-based diagnostic criteria. IBS is characterized by abdominal pain or discomfort and altered bowel habits. Although the etiology is multifactorial, recent understanding of the pathophysiology of IBS has revealed that variations in the normal gut microbiota may have a role to play in the low-grade intestinal inflammation associated with the syndrome. IBD: encompassing both UC and CD, is characterized by a chronic and relapsing inflammation of the GI tract. UC and CD are generally described as chronic IBDs, although are distinct diseases that differ both in their symptoms and inflammation pattern. Specifically, CD is a chronic, segmental inflammation of the GI tract and although the etiology is not yet clear, it is defined as a complex trait that results from the interaction between the host genetics and the gut microbial population. UC is generally characterized by inflammation and ulceration of the lining of the colon. The onset of both conditions is, in general, not thought to be due to a single causal organism but by a general microbial Dysbiosis in the gut, systemic diseases such as type 2 diabetes (T2D) and obesity: Obesity and related disorders, such as T2D and metabolic syndrome, have become increasingly common in recent decades. Obesity is a complex syndrome that develops from a prolonged imbalance of energy intake and energy expenditure. Although lifestyle factors, diet and
