Professor Owen Epstein is a renowned and pioneering professor of gastroenterology, based at the Royal Free Hospital in Hampstead, London. He has a special interest in the innovation of healthcare and the technologies used to ease the patient journey. These include whole bowel wireless capsule (pill) endoscopy and hydrogen or 13C breath testing variously for lactose intolerance, small intestinal bacterial overgrowth, Helicobacter pylori, stomach pump function and colon cancer screening using minimally invasive colon capsule endoscopy. He also has considerable experience in the physiological assessment of the vagus nerve and stress and, in particular, its relationship to abnormal gut feelings. Professor Epstein has had a hugely successful career and is regarded as one of the leaders in minimally-invasive techniques and a gentler patient journey.
