Dr Pannick is a Consultant Gastroenterologist in London, and works in the NHS at Chelsea & Westminster Hospital NHS Foundation Trust. He qualified at the University of Cambridge and University College London, graduating with Distinction in Clinical Practice in 2007. He then completed his Internal Medicine and Gastroenterology training at hospitals across the competitive Northwest London rotation.

Dr Pannick is an expert in the management of a broad range of conditions, including heartburn, reflux, abdominal pain and bloating, diarrhoea and constipation. He specialises in endoscopy, functional gastrointestinal disorders like irritable bowel syndrome, and clinical nutrition. Dr Pannick also leads the medical Clinical Nutrition service at the West Middlesex University Hospital. As well as patients with new symptoms, Dr Pannick regularly sees patients with chronic diseases like inflammatory bowel disease (ulcerative colitis and Crohn’s disease), gastro-oesophageal reflux disease, eosinophilic oesophagitis, functional dyspepsia, irritable bowel syndrome, coeliac disease, microscopic colitis, bile acid diarrhoea, and small intestine bacterial overgrowth.

Dr Pannick performs hundreds of endoscopic procedures each year, including gastroscopy, percutaneous endoscopic gastrostomy, flexible sigmoidoscopy, colonoscopy with polypectomy, and capsule endoscopy. Together with a team of colleagues, he also provides an emergency endoscopy service for patients with gastrointestinal bleeding. His endoscopy performance measures – for completion, comfort, and polyp detection – exceed national targets, and he is fully accredited with the UK’s Joint Advisory Group on GI Endoscopy. 

During his training, Dr Pannick also completed a PhD at Imperial College London, with a thesis on the team-based delivery of medical care. His academic work has been cited more than 270 times in scientific literature, and was highlighted by the US Agency for Healthcare Research and Quality for its lasting importance in the field of patient safety.

Dr Pannick has published papers in some of the world's leading medical journals, including the BMJ and JAMA Internal Medicine, and was a finalist in the UK’s Health Service Journal awards. He regularly teaches undergraduates, junior doctors, and trainee specialists, and has delivered regional lectures on the management of gastrostomy tubes and gastrointestinal bleeding.

Whatever the patient’s concern – new worrying symptoms, a chronic disease needing ongoing care, or uncertainty about a diagnosis – Dr Pannick’s approach is thoughtful, thorough, and kind. He has outstanding feedback from his patients and his colleagues.
