Getting to know Dr Sweis

  • Why did you choose to become a part of OneWelbeck

    I have a close relationship with many of the consultants at OneWelbeck having worked with most in the NHS over the years and having trained with several others. I have sent members of my family to OneWelbeck and felt it to would be right for me to join the team. Also, I have put together an Upper GI Physiology unit at OneWelbeck which will replicate the reputable unit that I have run for many years at University College London Hospital, my NHS base.

  • Why did you choose to specialise in disorders of function of the GI tract?

    This is a field which almost everyone has personal experience with but receives very little training in medical school and as a junior doctor. It is the bread and butter of gastroenterology. I decided early to specialise in this field and to delve deep into the underlying problems, methods of testing and treatments. I completed my PHD and continue to publish widely in this field, including co-authoring many of the national and international guidelines. My interests include problems in the oesophagus (disorders of swallowing, reflux, pain), stomach (vomiting, pain) and colon (disorders of diarrhoea, constipation, IBS).

  • How can I decide what treatment is best for me?

    I spend a long time just listening and gathering information regarding your main problems and priorities. I then offer the tests that allow us together to reach the best answer to what the problems might be, after which I take you step by step through what treatments are available in an open and honest way such that you have enough time to ask questions, consider your options, understand the risks and decide together on the best way forward.

  • Is there any other treatment available to treat oesophageal problems other than just taking omeprazole?

    Yes, I have an interest in treating a variety of conditions that may require more than just ‘a tablet’. For example, eosinophilic oesophagitis is a condition like asthma but in the oesophagus which is under-recognised but common that can be treated with medication similar to what asthmatics use. Also, careful oesophageal stretching might be needed if there is associated scarring/narrowing. To avoid having surgery, I also treat reflux with a novel technique called Trans-oral incisionless fundoplication (TIF), which is not offered on the NHS and is available in very few private centres in the UK. For conditions such as achalasia, another under-recognised swallowing disorder, I offer specialised treatments such as per-oral endoscopic myotomy (POEM) which is offered in only a handful of units in the country and also is an alternative to surgery. Finally, in other conditions of burping and regurgitation, where suitable, I offer behavioural modification therapy which I teach in the clinic. There are yet a variety of other treatments that can be offered for many such conditions, but all will be discussed openly and you will always have plenty of opportunity to ask questions and return at a later stage if you need time to consider.
