For people whose IBS keeps coming back

IBS symptoms not improving?

You’ve changed what you eat. You’ve tried to identify triggers. You’ve spent months trying to figure it out. So why are you still struggling?

Debra Thomas, Registered UK Dietitian explaining the low FODMAP plan to a client.

If you’re here, chances are this isn’t a new problem.

You’ve probably already searched for answers online, experimented with different foods, cut things out of your diet, tracked symptoms, or followed advice that promised relief.

Yet despite all that effort, you’re still dealing with symptoms that continue to disrupt your daily life.

This is where many people become stuck.

Not because they aren’t trying hard enough, but because the reason symptoms continue isn’t always obvious.

After working with thousands of people with IBS, I’ve seen the same pattern repeatedly: people are putting significant effort into solving the problem but are focusing on the wrong things, overlooking important patterns, or struggling to make sense of conflicting information.

If your IBS symptoms are not improving, there is usually a reason.

The challenge is identifying what that reason is.

First, let's look at why so many people stay stuck, even when they're doing everything they can.

THE PATTERN I SEE MOST

Why so many people continue struggling with IBS symptoms

By the time someone reaches out to me, they’ve usually spent months, and often years, trying to improve their symptoms.

They’ve removed foods, downloaded trackers, read articles, and followed advice from multiple sources.

Yet they’re still asking the same question:

“Why am I still struggling?”

One of the most frustrating things about IBS is that effort and results don’t always move together. I’ve worked with people who:

  • were avoiding more and more foods without seeing consistent improvement
  • kept detailed food and symptom diaries but struggled to spot meaningful patterns
  • found that symptoms changed even when they were eating the same foods
  • were constantly analysing every meal without gaining confidence in their choices
  • Had tried many medications and supplements

Yet they still didn’t feel they understood what was driving their symptoms.

In reality, the issue is often not a lack of effort or information. It’s a lack of clarity about which factors actually matter.

So what are the most common reasons IBS symptoms don't improve? Here are the patterns I see again and again.

Common reasons IBS symptoms don't improve

1

You're focusing on individual triggers, not the bigger picture

Many people try to identify a single food, ingredient, or trigger that explains everything.

But symptoms don’t always work that way.

For example, you may react differently to the same food on different days, or find that removing a suspected trigger doesn’t lead to the improvement you expected.

Often, people focus on individual events while missing the broader pattern connecting them.

As a result, they spend months chasing possible triggers without gaining real clarity about what’s driving their symptoms.

2

You've made changes, but not the right changes

Making dietary changes doesn’t automatically mean you’re addressing the factors most relevant to your situation.

Many people have already removed foods, restricted their diet, or followed advice they found online.

Some have tried low FODMAP. Others have cut out dairy, gluten, onions, garlic, or a long list of foods they suspect may be causing problems.

Yet despite these changes, symptoms can continue.

The challenge is that generic advice can only take you so far. What helps one person may be completely irrelevant for another.

3

You're trying to solve a complex problem alone

When symptoms continue for months or years, most people become their own investigator.

They analyse meals, monitor symptoms, look for patterns, and research possible explanations.

The difficulty is that you’re trying to evaluate a complex situation while living inside it every day.

This can make it difficult to stay objective and easy to overlook important factors.

4

You're gathering data but not interpreting it correctly

Many people arrive with pages of notes, symptom trackers, food logs, and observations.

The issue is rarely a lack of information.

The issue is understanding what that information actually means.

Without a clear framework, it’s easy to miss important patterns or focus on the wrong conclusions.

The missing piece isn't more effort

If IBS is not getting better despite everything you’ve tried, the answer is not always another restriction, supplement, or strategy.

Sometimes the missing piece is understanding where to focus your efforts in the first place.

Because when symptoms persist, the challenge is often no longer finding information. It’s knowing which information matters, which factors are most relevant to you, and what to do next.

And that’s where many people realise they no longer need more advice. They need clarity.

If you've been doing everything you can and still feel stuck, this next part is worth reading slowly.

Why symptoms can continue despite your best efforts

If you’ve been actively trying to improve your symptoms, it’s easy to assume that a lack of progress means you’re doing something wrong.

In most cases, that isn’t true.

Many of the people I work with are highly motivated. They’ve invested time, energy, and attention into understanding their symptoms. They’ve made changes, tracked patterns, and tried to be proactive about their health.

When you’re living with symptoms every day, it can be difficult to know which information deserves your attention and which information is simply creating more noise.

You may find yourself:

Over time, this can become exhausting.
Not because you’re unwilling to do the work, but because the next step is no longer obvious.
At that point, the issue is often not a lack of commitment.
It’s understanding which factors are most likely contributing to your symptoms and where your attention is best focused.

When it may be time to get professional guidance

There comes a point where continuing to gather more information doesn’t necessarily bring you any closer to an answer.

You may have read articles, listened to podcasts, followed recommendations online, and spent considerable time trying to make sense of your symptoms.

Yet you still don’t feel confident about:

This is often the stage where professional support becomes valuable.

Not because you haven’t tried hard enough. And not because you’ve failed.

But because having an experienced professional look at your situation from the outside can provide a level of objectivity that is difficult to achieve on your own.

Sometimes a fresh perspective can help uncover patterns and opportunities that are difficult to see when you’ve been managing symptoms on your own for a long time.

You may benefit from professional guidance if:

If that sounds familiar, it may be worth exploring whether personalised support could help you make sense of what has been keeping you stuck.

Here's exactly what working together looks like when symptoms have lingered for too long.

How I help people with persistent IBS symptoms

Many people come to me after months or years of trying to figure things out on their own.

They’ve often accumulated a lot of information, but they’re still unsure what to do with it.

My role is to help identify patterns, review what’s already been tried, and create a practical plan based on your individual circumstances.

Together, we look at the bigger picture rather than focusing on isolated symptoms, individual foods, or random pieces of information.

The goal is to identify:

As an IBS Specialist Dietitian, I take a holistic approach to your diet rather than focusing only on low FODMAP. We look at your overall eating pattern first, then use the low FODMAP approach where it’s most appropriate to help you understand your symptoms and avoid unnecessary food restrictions.

The aim isn’t simply to remove more foods. It’s to identify what is relevant to your situation and create a plan that fits your lifestyle. 
I’ll also guide you through each stage of the process, helping you stay on track and making sure you’re not left trying to work everything out on your own.

Rather than constantly jumping from one strategy to another, we work towards a clearer understanding of what is happening and a more structured path forward.

Every person I work with has a different history, different experiences, and different challenges. That’s why the process is tailored to you rather than based on generic advice.

For many people, the biggest benefit is having a structured approach rather than constantly guessing what to try next.

By working through the low FODMAP process together, many people complete it more quickly and efficiently than if they were trying to manage it alone. Regular sessions also provide accountability, helping you stay on track and move confidently through each stage.

If you’ve been trying to solve persistent IBS symptoms alone and feel unsure what to do next, a discovery call is a good place to start.

Before deciding whether professional support is right for you, it can be helpful to see how others felt before we worked together, and what changed afterwards.

Stories from people who felt stuck with their symptoms

Frequently Asked Questions

Can an IBS Dietitian help if I've already tried changing my diet?

Yes. Many people seek support after they’ve already made dietary changes themselves. Often the challenge isn’t a lack of effort, but understanding which changes are relevant to your situation and what to focus on next.

Many people come to me after trying low FODMAP or other dietary approaches without achieving the results they hoped for. A personalised review can help identify whether important factors may have been missed and what your next steps should be.

If you’ve already tried to manage symptoms yourself, continue to struggle, and feel unsure what to do next, professional guidance may help provide the clarity and structure you’re looking for.

The discovery call is an opportunity to discuss your situation, understand the challenges you’re facing, and determine whether personalised support would be appropriate for you.

Not necessarily. Many people are surprised to discover that the low FODMAP diet doesn’t need to be as restrictive as they first thought. The goal is to identify which foods you tolerate and expand your diet where possible, rather than create unnecessary restrictions.

Many people feel this way before reaching out. In reality, it’s often not a lack of effort that’s holding them back. A fresh perspective can help identify patterns, opportunities, or next steps that may have been overlooked.
