Living with Irritable Bowel Syndrome (IBS) can be exhausting. The ongoing bloating, discomfort, and unpredictable flare-ups can easily take over your daily life, especially when simple changes don’t seem to help. We asked The Functional Gut Clinic, who specialise in uncovering what's really driving IBS symptoms, to find out how testing can help you get real answers instead of guesswork.
What is IBS, and why is it so misunderstood?
“IBS affects around 1 in 10 people and can show up as constipation (IBS‑C), diarrhoea (IBS‑D), a mix of both (IBS‑M), or symptoms that change over time (IBS‑U). Despite affecting so many, the condition remains poorly understood, and there’s still plenty of misinformation about what causes it.
“For example, sugar doesn’t cause IBS, and while skipping meals might seem to offer relief, irregular eating patterns can actually make things worse. IBS is a complex interplay between the gut, brain, diet, and microbiome - and finding your triggers usually takes a bit of detective work.”
Why does testing make such a difference for IBS?
“IBS symptoms can overlap with issues such as food intolerances or bacterial overgrowth, so pinpointing the root cause is crucial to managing them properly. That’s where specialist testing comes in.
“At The Functional Gut Clinic, we provide advanced clinical breath and stool tests that help identify what’s actually happening inside your gut. These tests look beyond surface-level symptoms to uncover whether bacteria imbalances, intolerances, or motility issues might be involved.”
What does IBS testing actually involve?
“Our most common investigations include:
-
Breath testing for Small Intestinal Bacterial Overgrowth (SIBO), lactose intolerance, and now, Hydrogen Sulphide (H₂S) detection. This innovative test can identify “hidden” bacterial profiles that standard breath tests may miss - often the cause of persistent diarrhoea, bloating, or that distinct “eggy” odour in gas.
-
Stool analysis to assess gut inflammation, microbiome composition, and rule out infections.
-
Gut motility studies that track how food moves through your digestive system - something that can influence constipation, bloating, and pain.
“Understanding these underlying mechanisms means we can help personalise your treatment plan - whether that involves targeted dietary strategies, probiotics, or clinical therapies.”
How is the gut microbiome linked to IBS?
“Growing research continues to show that many IBS symptoms are linked to disturbances in the gut microbiome — the community of bacteria that live in your digestive system. When this delicate balance is disrupted, it can affect digestion, immunity, and even mood.
“That’s why treatments focusing on restoring the microbiome - such as probiotic supplementation - are becoming increasingly popular. Evidence suggests that certain probiotic strains can reduce bloating, ease discomfort, and support a healthier gut environment over time. Symprove, for example, is a water-based probiotic that is backed by clinical research, designed to reach the gut alive and active.”
What does an effective IBS management plan actually look like?
“Managing IBS often involves combining multiple approaches tailored to your individual needs. These may include:
-
Dietary adjustments like the low FODMAP diet, under the guidance of a gut-trained dietitian.
-
Lifestyle and stress management through relaxation, gut-directed hypnotherapy, or CBT.
-
Clinical therapies, including evidence-based supplements or short courses of targeted antibiotics when needed.
“When clinical testing is combined with thoughtful dietary and psychological support, it’s possible to significantly reduce symptoms and regain control.”
What’s the first step if I think I have IBS?
“IBS can feel overwhelming, but with the right clinical insight, it’s possible to get real answers, not just guesses. At The Functional Gut Clinic, our goal is to help you understand your gut better and guide you toward a plan that actually works for you.
“Whether you’re just beginning your journey or still searching for answers after years of symptoms, diagnostic testing could be the missing piece in understanding your unique gut health story.

FAQs
Here are answers to some frequently asked questions about IBS.
What tests are used to diagnose IBS?
“The Functional Gut Clinic use breath testing (for SIBO, lactose intolerance, and hydrogen sulphide detection), stool analysis, and gut motility studies to identify the underlying drivers of IBS symptoms.”
Is IBS caused by the gut microbiome?
“Research increasingly links IBS symptoms to imbalances in the gut microbiome, which can affect digestion, immunity, and mood - this is part of why microbiome-focused treatments are becoming more common.”
What's the difference between IBS-C, IBS-D, and IBS-M?
“IBS-C involves predominant constipation, IBS-D involves predominant diarrhoea, IBS-M is a mix of both, and IBS-U refers to symptoms that change or don't fit a clear pattern over time.”
