Dr John O'Donohue is a Consultant Gastroenterologist in London, UK. He has over 20 years’ experience and expertise in gastroenterology at consultant level.
What is important to him in his Practice
'Communication skills are particularly important to me. I pride myself on being a good
listener, first developing a rapport with patients before making a diagnosis
and agreeing a treatment plan with them. I also enjoy performing endoscopy well
and making it a comfortable and not an off-putting experience. It gives me
great satisfaction to see patients get the best treatment, and I take great
pride in my excellent feedback from my patients’.
Training and Qualifications
Dr O'Donohue qualified from University of Dublin, Trinity College, in 1987. He was awarded
the Blaney Gold medal for First in Medicine, St James' Hospital, in the final
medical examinations in 1987.
Dr O'Donohue completed pre-registration training in Dublin before he moved to London in 1990 to undertake his specialist Registrar training in Gastroenterology and Hepatology at the world-famous King's College Hospital Liver Unit and at St.
Bartholomew's/Homerton Hospital, London. He undertook laboratory and clinical
research in King’s College Hospital resulting in numerous original publications
and his post-graduate MD thesis, awarded for original research including
numerous original publications in the field of primary biliary cholangiopathy. After
this he completed his specialist training as a Senior Registrar at the Western
Infirmary, Glasgow, gaining expensive experience in inflammatory bowel disease.
He then returned to London as a Consultant Physician and Gastroenterologist in the NHS in 1998, at Lewisham and King’s College Hospital, practising both in General Medicine and Gastroenterology. He started private practice in 2000.

Performing high-quality and comfortable endoscopy is a particular interest of his. He has extensive experience in endoscopy and receives referrals for advanced
procedures from other doctors, including complex (large) colonic polyps. He
performs a comprehensive range of endoscopic procedures, including gastroscopy,
colonoscopy, sigmoidoscopy, ERCP and video capsule endoscopy of the small
bowel. He offers patients a choice between local anaesthetic, conscious (mild)
sedation, or deep sedation depending on their preference and expectations.

Very thorough - took time to look at my previous rest results from a few years ago. The endoscopy was performed professionally and he took time to explain the results. Would highly recommend John. Thank you for a great experience.
I booked an appointment with John having experienced issues with my bowel over an extended period and was throughly impressed by the timely availability for an appointment and the through diagnosis and treatment he was able to provide me. Thanks again John!
Outstanding care and compassion shown towards my mum as she can be quite a difficult patient. Dr O’Donohue treated her with remarkable patience, dignity and understanding of a difficult case thought out. He took the time to listen carefully, explain every thing clearly and never once made her feel rushed or dismissed. His professional, calm manor and genuine kindness made a very stressful situation much easier for our family.
