Applying Professional Care that Works for Individual Gut Patients

Professor Bjarnason has won practically every award for his work in advancing care for gut patients. He has pioneered and championed the cause for medical innovation and is at the forefront of evidence-based research prior to the application of novel therapies. His whole professional approach is driven by the need for scientific rigour behind all aspects of intestinal medicine.

With regard to patient care he is devoted to the individual and will always consider the full broad-based and holistic approach to each patient. For example, in the treatment of Irritable Bowel Syndrome (IBS) he takes the lead with a multi-disciplinary approach, involving appropriate medical specialists including Geneticists (especially with regard to diagnosis and P4 Medicine), Gastroenterologists, dietary experts and liaison with Psychiatrists. In this way, patients can expect the best possible care for the 'whole patient' that modern medicine has to offer. One of Prof's latest projects has been into conducting well constructed clinical trials to look into the role that probiotics have in treating IBS, IBD and ulcerative colitis. This work has highlighted the need for patients to be highly selective over their choice of probiotic brand. (See details - below).

Prof Bjarnason has won some of the most important medical awards, but has never been one to sit on his laurels. He is devoted to his patients and offers them a world-class service for the diagnosis and treatment of all gastrointestinal diseases. This is characterised by his application of rapid diagnostic work-up using state of the art technology for diagnosis and staging, all married to the best research work and proven clinical practice.

The underlying principle is the to aim to minimise and avoid as much as possible the use of expensive, time-consuming and uncomfortable invasive tests such as traditional endoscopies, but without ever compromising the ability to arrive at the correct diagnosis. Prof will utilise all the latest, validated and highly sensitive tests. These tests may include, but are not limited to the following:

  • Intestinal permeability,
  • Wireless capsule enteroscopy,
  • Intestinal disaccharidase deficiency,
  • Bile acid-malabsorption,
  • Intestinal inflammation (via the faecal calprotectin test),
  • Intestinal transit,
  • Screening tests for Coeliac disease and Helicobacter pylori,
  • Imaging including MRI,
  • When an abnormality is evident this allows targeted investigation of the problem and treatment.

  • Gastroenterology
  • Internal Medicine
  • Chemical Pathology

  • New multi-strain probiotic drink effective against IBS and IBD

    Which Probiotic? The latest evidence shows that despite the hype only one really seems to work...
    The use of probiotics such as Symprove is not a cure and only a part of the more integrated and multi faceted treatment of IBS. Rather the patient with IBS needs to consider the range of probiotics on merit and this is almost invariably down to the results of properly designed and executed clinical trials. This may not be easy, but an experienced Gastroenterlogist with an interest in IBS will be of help. No probiotic is at present prescribable by GPs. For many patients the 50-70% reduction in symptoms will come as a significant respite.
