The Role Of Irritable Bowel Disease ( Ibd )

Decent Essays

Although the gut microbiota are involved in a range of functions within the human body, this essay will focus on their role in the development of Irritable Bowel Disease (IBD). The human gut microbiota play a significant role in the metabolic health of individuals with irritable bowel diseases such as Ulcerative Colitis (UC) and Crohn’s Disease (CD). IBD, UC and CD are chronic gastrointestinal illnesses, all of which have an uncertain etiology. Symptoms of these illnesses can include diarrhoea, weight loss, ulceration, proliferation and even total obstruction of the gastrointestinal (GI) tract. (1). However the causes of these diseases are not strictly known(2). There are a vast number of bacterial species that reside within the GI tract, some of which can play a role in producing inflammation. It is believed that microbial patterns may play a role in causing IBD. The innate immune system may play a role in altering the gut microbiota profile. Certain pathogens have also been found to play a role in the development of IBD. Finally, diet and nutrition play a role in IBD, however certain nutrients are believed to have both positive and negative effects. This essay will aim to critically explore what is responsible for IBD: both internal and external factors that influence the human gut microbiota, and hence trigger IBD, or more specifically; an abnormal immune response in a vulnerable individual, or a deviation in immune function that leads to an altered immune response
