Irritable Bowel Syndrome: Comprehensive Multidisciplinary Management Including Dietary Modification, Gut-Brain Axis Education, Pharmacological Options and Lifestyle Optimisation

Hello I am the gastroenterology nurse specialist. Dr Patel has discussed the diagnosis of IBS with you. How are you feeling about that?

Relieved the tests are normal but honestly confused. If everything is fine why do I feel so awful so much of the time?

That is a very understandable reaction and you are not alone in feeling that way at all. IBS is a real recognised medical condition. The tests are normal because IBS does not cause any damage to your bowel that we can see on a colonoscopy or scan but it does affect how your gut actually works and how your brain communicates with your digestive system. Your symptoms are completely real and valid.

So my bowel is structurally normal but it does not function properly? That does make sense actually.

Exactly right. Now tell me about your specific symptoms so I can understand your situation better. When do they tend to happen and what makes them better or worse?

Constant bloating pain after eating and alternating diarrhoea and constipation. Definitely much worse when I am stressed at school — I am a teacher.

The link between stress and your symptoms is very important. It is actually a classic pattern in IBS and it tells us that the gut-brain connection is playing a significant role. You mentioned you have already tried eliminating gluten and dairy — what happened when you did that?

I cut them out for three weeks each and absolutely nothing changed. I felt like giving up altogether.

I completely understand that frustration. The reason blanket eliminations rarely work is that there is no single trigger food that affects everyone with IBS. A much more targeted approach is the low FODMAP diet which is done in three phases — restriction for four to six weeks then systematic reintroduction to find your specific triggers then personalisation of your diet — all under the guidance of a specialist dietitian who makes it manageable for your lifestyle.

What else can I do to help myself?

Because the gut and brain are so closely connected managing your stress levels can have a direct impact on your symptoms. Eating regular meals at consistent times staying well hydrated getting enough good quality sleep and regular physical activity all make a significant difference. There are also medication options we can consider and I recommend starting a symptom diary for two weeks to identify your trigger patterns.

How long does it take for the FODMAP diet to work?

The restriction phase typically lasts four to six weeks. Some people notice improvement within the first two weeks but for others it takes longer. The dietitian will monitor your progress and guide the reintroduction phase to identify your specific trigger foods.

Can stress really cause IBS flare-ups?

I will start the diary tonight. This is really helpful.

Should I be worried about getting colon cancer?

IBS does not increase your risk of developing colon cancer. The reassurance from your normal colonoscopy is that there were no concerning findings. IBS is a functional disorder not a structural one and it does not lead to cancer.

Can probiotics help with IBS?

Some specific probiotic strains have shown benefit for IBS symptoms particularly for bloating. I would recommend discussing this with the dietitian who can advise on which probiotic may be appropriate for your specific symptom pattern. Yes absolutely. The gut and brain are directly connected through something called the gut-brain axis. When you are stressed your body releases hormones that affect how your gut moves and how sensitive it is. This is why stress management is important. I will refer you to our gastroenterology dietitian today. Here is an IBS information booklet to take home. I would like to review your progress in about six to eight weeks.
