    Dr Rami Sweis

    Consultant Gastroenterologist


    Dr Rami Sweis consults privately at The London Gastroenterology Centre on Welbeck Street. He is also Consultant Gastroenterologist and the Upper GI Physiology Lead at University College London Hospital (UCLH). He specialises in a wide range of upper and lower gastrointestinal disorders, with a particular emphasis on managing benign and pre-malignant Upper GI disorders of the oesophagus and stomach for which he has an international reputation.

    Dr Sweis is the President of the Association of GI Physiologists (AGIP), a member of the Neurogastroenterology & Motility (NGM) and of the Oesophageal section of the British Society of Gastroenterology (BSG).

    Dr Sweis has extensive expertise working with a spectrum of conditions including: swallowing problems, heartburn, regurgitation, chest pain, reflux disorders, achalasia, oesophageal spasm, vomiting, abdominal pain, constipation, diarrhoea and IBS.


    After obtaining his Bachelors in Biology and Psychology in 1994 from the University of Illinois at Chicago, Dr Sweis went on to complete his primary medical qualification at the University of Edinburgh in 1999. He also became a member of the Royal College of Physicians of Edinburg (RCPE).

    Dr Sweis undertook his specialist training in Gastroenterology in South East Thames during which time he also completed his PhD in Upper GI Physiology at Kings College Hospital and Guys & St Thomas’ Hospital in 2012. He was appointed as a Consultant Gastroenterologist at UCLH in 2014 and became a Fellow of the Royal College of Physicians (FRCP) in 2019.

    Dr Sweis was awarded the Fellowship of the Higher Education Academy (FHEA) in 2018 and he holds an Honorary Associate Professor position at University College London (UCL).

    • 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.
    What drives me?

    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.

    Research interests

    Dr Sweis is actively involved in research investigating the utility of novel technology and methodology in oesophageal function testing including catheter and wireless pH-monitoring for reflux disease and High Resolution Manometry for swallowing disorders. He is also interested in defining how such tools can help in treating patients with complex-benign disorders such as achalasia.

    Gastrointestinal treatment

    Being highly experienced in Upper GI Physiology and an Advanced Endoscopist, Dr Sweis is in the unique position to offer patients an alternative approach to manage many GI conditions, from behavioural modification therapy to complex endoscopic treatment. Combining both his experience and his patient-centred approach, Dr Sweis will offer a comprehensive ‘holistic’ assessment such that you are fully informed of all the risks, benefits and merits of any treatments before they are given, with the aim of arriving to the best decision for managing your condition together in a calm, unhurried manner.

    Where appropriate, Dr Sweis also offers a ‘One-Stop-Shop’ whereby the clinical assessment, endoscopy and treatment can be undertaken in the same afternoon, thus minimising anxiety and avoiding frequent travels.


    Dr Sweis sees patients for a wide range of conditions including:

    • Swallowing disorders
    • Achalasia
    • Reflux symptoms/indigestion/Regurgitation/heartburn
    • Barrett’s oesophagus
    • General GI conditions
    • Vomiting
    • Chest and abdominal pain
    • Bloating
    • Irritable bowel syndrome
    • Constipation/Diarrhoea



    Specialist endoscopic and other treatments that Dr Sweis can offer:

    • Dilatation of the oesophagus and stomach
    • Botox of the oesophagus and stomach
    • Wireless pH Monitoring
    • Endoscopic Mucosal Resection
    • POEM (Per-oral Endoscopic Myotomy)
    • Stretta
    • TIF (Trans-oral Incisionless Fundoplication)
    • Radio-Frequency ablation
    • Barrett’s, Stomach surveillance
    • Colon screening and polyp removal/EMR
    • Diaphragmatic breathing/behavioural modification therapy
    Journal publications

    Dr Sweis continues to publish and collaborate with fellow experts and oesophageal units in the UK and abroad, and is frequently invited to speak at national and international conferences. He also organises and runs his own hands-on physiology courses and symposiums.
