  3. Fact Sheet: Gut Bacteria and Irritable Bowel Syndrome


    By: Eamonn M. M. Quigley, MD

    Does bacteria play a role in IBS? If so, is it helpful or harmful? What about antibiotics, or probiotics? Bacteria are present in the normal gut (intestines) and in large numbers the lower parts of the intestine. These "normal" bacteria have important functions in life. A variety of factors may disturb the mutually beneficial relationship between the gut bacteria and its host – and disease may result. The possibility that gut bacteria could have a role in irritable bowel syndrome (IBS) may surprise some; there is indeed, now quite substantial evidence to support the idea that disturbances in the bacteria that populate the intestine may have a role in at least some patients with IBS. This article looks at recent findings about possible influences of bacteria in IBS, which may be either negative or positive, and at various treatment approaches.

  4. Fact Sheet: Post-infectious Irritable Bowel Syndrome: A Sub-Type of Irritable Bowel Syndrome


    By: Robin Spiller, MD

    Irritable bowel syndrome is one of the most common gastrointestinal (GI) disorders. Within this large group of people, there is a small subgroup whose symptoms begin suddenly. It happens after what appears to be a bout of infection in the GI tract (gastroenteritis). How often do persons who suffer bacterial gastroenteritis develop IBS? Who gets post-infectious IBS and what causes the disorder? How is it treated? A review of the topic is presented.

  8. Fact Sheet: Could Probiotics Help Alleviate your Functional Gastrointestinal Symptoms?


    By: Nancy DeMaria; Danielle Maier, PA-C; Yehuda Ringel, MD

    There is evidence that a normal bacteria composition of the intestinal microbiota play an important role in the development and normal functioning of the intestinal tract. Recently researchers have been studying the role of normal intestinal bacteria (also called intestinal microbiota) in maintaining healthy and normal GI function.

  10. Fact Sheet: How Manís Commonest Infection Kept its Secret: The H. pylori story


    By: W. Grant Thompson, MD, FRCPC

    In a previous article, I discussed the great prevalence of peptic ulcer disease in the twentieth century (Peptic Ulcer: A Twentieth Century Disease – IFFGD Fact Sheet No. 509). Ulcer researchers became convinced that gastric acid was the cause of peptic ulcer and expended great effort to understand the physiology of acid secretion and to develop diets, drugs and surgical procedures to control acid secretion. Why did it take so long to understand the truth about ulcer disease? Does this history have any implications for the study of the functional gastrointestinal diseases (FGIDs)?
