Dr Rami Sweis
Lead in Upper GI Physiology at UCLH; Honorary Senior Lecturer at UCL
Dr Sweis is a specialist in endoscopy with particular expertise in investigating and managing complex benign and malignant upper gastrointestinal disorders.
He has particular expertise in conditions such as achalasia, oesophageal spasm as well as reflux-related disorders such as heartburn and regurgitation. He also has a specialist interest in using advanced endoscopic techniques to classify and treat Barrett’s oesophagus. Furthermore he is an experienced colonoscopist.

Dr Sweis is a Consultant Gastroenterologist at University College London Hospital. He completed his Bachelor’s degree from the University of Illinois at Chicago (1994) and his medical education from Edinburgh Medical School (1999). He trained in Gastroenterology at Guy’s & St Thomas’ Hospitals, Kings College Hospital and South East Thames. He completed his PhD at Kings College London in 2012. He was appointed at UCLH in March 2014 as Consultant in Gastroenterology & Upper GI Medicine. He is also Upper GI Physiology Unit Lead at UCLH
- During my training in Gastroenterology in SE Thames, I spent 4 years at St Thomas Hospital to complete a PhD in upper GI Physiology. I gained extensive experience in Oesophageal Physiology techniques including High Resolution Manometry (HRM) and ambulatory pH monitoring (catheter-based ph, Impedance-pH and wireless (Bravo) pH monitoring). My research has led to a number of publications which have had an impact on the international classification of oesophageal motor disorders and methods by which we investigate reflux disease. I continue to be an active member of the international HRM Working Group. I am also a member of the BSG Neurogastroenterology& Motility Committee and the Clinical Representative of the AGIP Committee. As a locum Consultant in East Kent I led the lower GI EMR service while I also trained at UCH in upper GI endoscopic techniques. I secured a position as Consultant in Upper GI Medicine at UCLH in March 2014. I am also upper GI Physiology lead at UCLH.
Being both an experienced upper GI physiologist and an advanced endoscopist, I find myself in the unique position. As the majority of upper GI conditions can have a variety of causes and treatments, I like to allow patients to take the lead in proposing how they would like me to proceed. In functional disorders in particular, I can treat many conditions medically as well as with behavioural modification therapy. I like to take my time and provide all the information possible (having undergone the physiology tests myself in the name of research!). Where endoscopic investigation/treatments are requested (or required), I take the patient through all the risks and benefits for every procedure so that ultimately the patient is in control every step of the way.
Dr Sweis’ research centred on advancing the technology and methodology for investigating and treating reflux and swallowing disorders; primarily catheter and wireless (Bravo) pH-monitoring and High Resolution Manometry. He continues to publish and collaborate with fellow experts and oesophageal units in the UK and abroad, and is regularly invited to speak and train at national and international conferences. He is an active member of the international High Resolution Manometry Working Group, which is responsible for classifying oesophageal disorders. He is also a member of the Neurogastroenterology& Motility Committee of the British Society of Gastroenterology and the Clinical Representative of the Association of GI Physiologists (AGIP) Committee.
