Professional background

Anton Emmanuel obtained his medical degree from London University. He is A Professor in Neuro-Gastroenterology at University College London and Consultant Gastroenterologist at University College Hospital and the National Hospital for Neurology and Neurosurgery (Queen Square). Prior to this he was Senior Lecturer at Imperial College and Honorary Consultant Gastroenterologist at St Mark's Hospital.

His clinical work encompasses being director of the GI Physiology Unit at University College Hospital as well as providing a general gastroenterology service. His research includes gut neurophysiology and the study of the aetiology and management of functional gastrointestinal disorders of the upper and lower gut. He was appointed as editor in chief of Clinical Medicine and Commentary (the journals of the Royal College of Physicians), having served a similar role for eight years at Frontline Gastroenterology. He is deeply committed to developing the journals as a valued asset for members of the College.

Patients are assessed within a multi-disciplinary environment, with structural and physiological investigations undertaken as a one-stop visit alongside a focussed clinical assessment. The Unit is always happy to discuss cases by phone in order to streamline referral for the patient.
