    Keywords : irritable bowel syndrome IBS ; visceral perception; rectal perception; visceral hypersensitivity; gastrointestinal symptoms; hypervigilance; selective attention; stress; small intestinal bacterial overgrowth; rectal barostat; small bowel motility; gastrointestinal dysmotility;

    Abstract : Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder characterized by abdominal pain and/or discomfort together with abnormal bowel habits. The pathophysiology is complex and incompletely understood. READ MORE

  2. 7. Managing irritable bowel syndrome - Dietary approaches and food intolerance

    Author : Sanna Nybacka; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Irritable bowel syndrome; diet; FODMAP; food intolerance;

    Abstract : Irritable bowel syndrome (IBS) is a complex disorder where diet plays a pivotal role in symptom generation for many patients. The aim of this thesis was to explore how diet and self-perceived food intolerance relate to gastrointestinal (GI) symptoms among patients with IBS, and within different manifestations of IBS.

  3. 8. Irritable bowel syndrome - a disorder of gut-brain interaction

    Author : Irina Midenfjord; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Irritable Bowel Syndrome; gastrointestinal symptom severity; anxiety; depression; neurophysiological aberrations; psychological alterations; central sensitization;

    Abstract : Irritable bowel syndrome (IBS) is a common and multifactorial functional gastrointestinal (GI) disorder characterized by altered gut-brain communication. Due to the complexity of gut-brain interactions, the aim of this thesis was to enhance the understanding of associations between GI symptom severity and measures from multiple levels along the gut-brain axis in IBS patients.

  4. 9. Pathogenetic mechanisms in irritable bowel syndrome

    Author : Hans Törnblom; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Irritable bowel syndrome; functional gastrointestinal disorder; immunohistochemistry; full-thickness biopsy; enteric nervous system; autoantibody; gastroenteritis; risk factor;

    Abstract : Aims of the thesis: To study new pathogenetic mechanisms in IBS; to find out if IBS is a neuromuscular disease affecting the small bowel; to study humoral factors in gut dysmotility associated with visceral neuropathy; and to study the natural history of post-infectious gastro-intestinal (GI) symptoms and risk factors for their development. Material and methods: In studies I and II, full-thickness jejunum biopsies from patients with severe IBS were investigated with immunohistochemistry. READ MORE
