The future – IBS research

Your Top 10 Research Priorities for Irritable Bowel Syndrome (IBS) in the UK and Republic of Ireland!

In 2021, Guts UK began the process of identifying the Top 10 Research Priorities for Irritable Bowel Syndrome (IBS) in the UK. It was important to us that patients, their families, carers and healthcare professionals decided this top 10 together, with equal voices.

Now, in 2023, we are delighted to announce your Top 10 Research Priorities for IBS.

Your top 10 research priorities for IBS.

We’d like to thank you most sincerely for your input throughout. In our first survey we had over 8,000 questions submitted by over 2,500 people. In our second survey over 1,700 people chose the questions which meant the most to them, which lead to our top 24 questions to take to our final workshop.  Your input has changed the future of IBS research in the UK. Thank you for starting us on the path towards true and lasting change for IBS patients in the UK and the Republic of Ireland. This would not have been possible without you.

Discover the priorities below, or look at the final report here.

Priority 1

1. Are all forms of IBS the same condition, or are there different types of IBS with different causes and needing different treatments?

Picture of Dr Dipesh Vasant“As clinicians with a specialist interest in IBS we have learnt that a ‘one-size fits all approach’ to treatment is inefficient. Personalising care is therefore a top priority. This will allow professionals to recommend the right treatment, at the right time, for the right patient! There is exciting emerging evidence that there may be new, previously unrecognised, subtypes of IBS. There is therefore an urgent need for further research to find out if recognising the different types of IBS using these new approaches can help guide tailored treatment plans and improve the outcomes for IBS suffers.”

-Dr Dipesh Vasant, Consultant Gastroenterologist, Manchester University NHS Foundation Trust.

“I think this is an excellent question as it may yield information which would be helpful to patients, carers and healthcare professionals alike going forward.”

-Miranda.

Priority 2

2. What causes bowel urgency (a sudden urgent need to go to the toilet) in people with IBS? How is this best treated and managed?

Photograph of Associate Professor of Primary Care and General Practitioner, Sarah Alderson. “One of the most distressing symptoms of IBS for my patients is bowel urgency. It has a huge impact on patients’ lives and ability to leave the house due to fear of not making the toilet. Whether it is urgency with diarrhoea or following constipation, it affects most with IBS and has the biggest impact on their quality of life.”
– Associate Professor of Primary Care and General Practitioner, Sarah Alderson.

 

Picture of James and his dog“This question is important as it has the most significant impact on the sufferers of IBS. There were other research-based questions that were also interesting but from a patient point of view, sudden urgency is the feeling that stops us from living a full life and gives sufferers the biggest anxiety.”

-James. Read James’s story here.

Priority 3

3. What causes pain and/or gut hypersensitivity in people with IBS, including spasms and cramps? Are there better ways to treat and manage these?

Picture of Dr Chris Black.“Abdominal pain is one of the core symptoms of IBS and can be debilitating. The impact on patients and their quality of life is often substantial. Unfortunately, pain in IBS can be challenging to treat effectively and existing approaches may not provide adequate relief. Further research to improve our understanding of what causes pain in IBS and to develop new treatments is, therefore, vital.”

-Dr Chris Black, Consultant Gastroenterologist.

Picture of Alexandra“This question is important to me because I experience gut hypersensitivity and experience pain daily from cramping caused by my IBS-D. I struggle every day to manage the cramps and it is linked to frequent and urgent bowel movements including diarrhoea. It’s hard to manage. I’ve tried all sorts of treatments, but none work very well so this leaves me with very little pain management options.

I struggle to work, go about my daily life and rely on other people to help support me. My gut is sensitive to most foods and the pain is hard to manage sometimes. The pain caused from IBS isn’t recognised widely either. Being able to have better treatment for the hypersensitivity and pain would mean I could live a more “normal” life which would be life changing. It is something extremely important to me as IBS has made my world so small it’s almost non-existent.”

-Alexandra. Read Alexandra’s story here.

Priority 4

4. Could a better understanding of the gut-brain connection in IBS lead to the development of new treatments?

Picture of Tiegan.“I have experienced a lot of anxiety with my IBS which I have noticed has a huge impact on my gut. The days where my anxiety is high (maybe because of an event where I don’t want my IBS to hinder the experience) are always the days that it is as its worst. Which I think is no coincidence. It is a constant cycle of my anxiety being high because of my IBS but then my IBS flaring up because of my anxiety.

While healthcare professionals know about the gut-brain connection in IBS I believe that if further research is done into its link we would find a whole host of new ways to approach this and in turn hopefully develop new treatments.”

-Tiegan. Read Tiegan’s story here. 

Picture of Professional Peter Whorwell.“What is going on in someone’s head can affect their tummy and vice versa. Identifying the pathways involved and how they can be modified, could help us develop better ways of treating conditions like IBS where these pathways don’t seem to function normally.”

-Professor Peter Whorwell, Professor of Medicine and Gastroenterology.

Priority 5

5. Do hormonal changes during the menstrual cycle, pregnancy and menopause affect IBS symptoms? If yes, could this understanding lead to new treatments?

Picture of Dr Rabia“Women are 1.5 x more likely to suffer from IBS than men. The hormonal changes a woman undergoes across her lifetime are vast and yet few clinical studies have concluded upon the precise role of female hormones in IBS. As it stands, women are left in the dark as to the impact of their menstrual cycle, pregnancy and menopause on their IBS symptoms. From contraception choice to postmenopausal hormone replacement therapy – women lack the information they require to make informed choices. This is an exciting, intriguing and crucial area of research because it cross pollinates two specialist areas which have long been uncoupled.”

Dr Rabia Topan, Gastroenterologist. 

Picture of Angelina“This question is important for several reasons. Although there is evidence to suggest that hormonal changes do affect the bowel during menstruation, pregnancy and menopause, there isn’t enough. Research needs to be done to demonstrate the connection further. As a woman who has suffered many symptoms of IBS during menstruation as well as being diagnosed with endometriosis, I find this question particularly important.

I hope research into this area will lead us to a greater understanding of the bowel and its connection between hormonal changes, which in turn will hopefully lead to faster diagnoses. As well I hope it encourages working partnerships with different healthcare professionals and practitioners within different specialities, in order to get the best outcome for patients.”

-Angelina.

Priority 6

6. How does mental health, particularly anxiety and depression, affect IBS? Do treatments for anxiety/depression reduce or stop IBS symptoms?

Picture of Professor Alexander C. Ford.“The brain and gut communicate through the nervous system and that communication travels in both directions, from the brain to the gut and vice versa. This communication system can influence many gut disorders, including irritable bowel syndrome (IBS). We know that in some people IBS can trigger the new onset of anxiety or depression, and in other people a history of anxiety or depression can be a risk factor for developing IBS in the future. How all these different factors act together in people with IBS to influence prognosis is not clear though. In addition, some drugs that are viewed as treatments for anxiety or depression may be beneficial in IBS. However, often these drugs are used in IBS at a much lower dose than is used to treat anxiety or depression, so whether these drugs are having a benefit because of their actions on the bowel or their actions on the brain is unclear.”

-Professor Alexander C. Ford, Professor of Gastroenterology and Honorary Consultant Gastroenterologist.

Picture of Sofie.“I know that my IBS and my mental health is completely exacerbated by each other. For me, my mental health and particularly IBS has ruined my life. Not just myself but many others too. It’s actually heart-breaking you have to learn a whole new way of life. It’s tough to have that battle with your mind and it’s almost like you have to learn a whole new normal.  I hope that one day that there is treatment that will help people like myself because everyone deserves to live the best life they possibly can.”

-Sofie. Read Sofie’s story here.

Priority 7

7. Are there ways for people with IBS to improve sensitivity in the bowel and/or improve control of their bowels e.g. through training with biofeedback?

Picture of Rebecca, Bowel Dysfunction Clinical Nurse Specialist.“It is important to continue to develop new ways of helping patients manage symptoms that they identify as impacting their quality of life, such as pain, bloating and urgency.”

-Rebecca Embleton, Bowel Dysfunction Clinical Nurse Specialist at County Durham and Darlington NHS FT.

“Initially I was sceptical about this question as I couldn’t believe that I could learn to manage my own pain and bowel movements. However, after learning more, Picture of Sarah.I now see this as an exciting development. Other treatments, such as biofeedback, could mean that IBS sufferers would actually have an element of control over their symptoms rather than simply tolerating them. There is so much we don’t know about IBS – the many different symptoms, how it develops and how it can be tested for, all of which are vital research areas. But it is also vital from a quality-of-life point of view to focus on positive and practical ways to help manage symptoms, many of which can have such a debilitating effect on the day-to-day life of the sufferer.”

-Sarah.

Priority 8

8. How can a fast and accurate diagnostic test be developed for IBS? How can different types of IBS be diagnosed more reliably?

Picture of Professor Chris Probert.“Many patients are distrustful of a clinical diagnosis of IBS, and many doctors investigate patients to help support the diagnosis by ‘ruling out’ other diseases. A test that will help make a positive diagnosis should hasten the diagnosis, reassure patients (and clinicians) and ultimate improve the management of people with IBS.”

-Professor Chris Probert, Professor of Gastroenterology.

Picture of Morgan“A fast diagnostic test would help people to begin the process of understanding and treating their condition sooner.  It also helps track how many people are living with IBS and enable access to the treatments that already exist and will hopefully come out research.”

-Morgan.

Priority 9

9. What changes in diet benefit people with IBS? Which diet is best for the long-term?

Picture of Sandy.“IBS is not nice. From the pain and bloating brought on by constipation, to the feelings of humiliation and loss of control caused by incontinence. IBS is a physical and a mental affliction. I’m so glad this question about diet and dietary changes is being prioritised, because food and drink can have such a big impact on IBS.

Further research is needed as a priority to identify trigger foods that may affect the patient causing symptoms, and how changes to their diet will improve their health and wellbeing.”

-Sandy. 

Picture of Yvonne“Approximately 8 out of 10 IBS patients believe that food impacts their gut symptoms. Answering this top research priority question for people with IBS would optimise the long-term effects of dietary change including its safety, minimising food-related anxieties, improving quality of everyday life, and reducing healthcare utilisation.”

-Yvonne McKenzie, first author of the British Dietetic Association’s evidence-based practice guidelines for the dietary management of IBS in adults (2016 update). 

Priority 10

10. Are treatments which balance the gut bacteria effective for people with IBS, including faecal transplants? Which prebiotics and probiotics are most effective?

Picture of Peter.“There is a bewildering amount of information on the web when it comes to the microbiome, including probiotics/prebiotics and other solutions available to correct a perceived imbalance in gut bacteria for the IBS sufferer. My wife has fought IBS for nearly 40 years and has tried many remedies. We need to better understand the microbiome and its relationship to IBS, and specifically which probiotics, prebiotics and other remedies are most effective when it comes to treating this condition.”

-Peter.

Photo of Dr Imran Aziz“IBS is associated with alterations in gut bacteria. Modulating the gut bacteria (e.g. through the use of prebiotics, probiotics or faecal transplant) might improve the symptoms of IBS, but the evidence is limited and conflicting. Hence, high-quality studies evaluating these approaches in IBS are needed.”

-Dr Imran Aziz, Honorary Consultant Gastroenterologist & Senior Clinical Lecturer. 

Priorities 11 - 24

11. What causes bloating in people with IBS and how is this best treated and managed?

12. What are the best ways to support people with IBS in managing their condition? How can health professionals best help with this?

13. Can accurate and reliable tests be developed to identify which foods are triggers for a person with IBS?

14. What causes diarrhoea in people with IBS and how is this best treated and managed?

15. Why don’t some health professionals take IBS seriously? What would help them to respond appropriately to people’s symptoms?

16. What causes fatigue in people with IBS and how is this best treated and managed?

17. What is the best form of follow-up care for people diagnosed with IBS including ongoing monitoring, treatment and support?

18. Does IBS affect other parts of the body other than the gut e.g. the skin or heart?

19. What is the best way to work out which foods trigger IBS symptoms? How can people with IBS best be supported to do this and to change their diet?

20. Is the presence of certain gut bacteria a risk factor for IBS? E.g. following the use of antibiotics.

21. Is IBS an autoimmune disease?

22. Which aspects of IBS treatment and care are best provided in primary (GP and community services) and secondary care (hospitals)? How can improvements be made?

23. Is stress or an emotional or physical trauma, either in childhood or in later life, a risk factor for IBS?

24. What do people with IBS feel is a successful outcome from treatment / management of their condition? How can this be measured?

What's next?

The future looks brighter. This is the first time you have been asked what research you’d like to see into your condition. Now, Guts UK is working hard to promote these questions and put them into ‘researchable’ format. IBS is a misunderstood and undervalued area of health. We are committed to paving the way for IBS research in the UK.

With your donations, we can fund more IBS research. Please donate today. 

The National Institute for Health and Research (NIHR) welcome applications for research towards conditions with top 10 priorities.

We finally have a direction for IBS in the UK, a condition that has been neglected and misunderstood for too long. Together, we’re changing that. Thank you. Please donate today, to help us fund more research, reach more people and empower people to seek help.

What is a PSP?

The James Lind Alliance (JLA) helps set up PSPs for a wide range of diseases. The purpose of a PSP is to identify and prioritise the unanswered questions for certain medical conditions, or areas of health.

The process of a PSP brings together patients, carers, doctors, nurses, scientists, researchers, dietitians and other health professionals, all with an equal voice. Together, they will decide the Top 10 Research Priorities for their condition.

How did we get to this top ten?

We started by asking everyone who is impacted by IBS to submit what questions they’d like IBS research to answer. You submitted a staggering 8,000 questions! We also contacted over 50 organisations across the UK to help us disseminate this survey to reach as many people affected by IBS as possible. 

In our second survey, over 1,700 people chose the questions that meant the most to them.

The final 24 questions were taken to our final workshop. We invited patients, carers and healthcare professionals to attend. With the expert help of the James Lind Alliance, the top 10 were decided.

Take a look at the full final report here.
