What Decides How Much Of Your Life Your Gut Takes

You had this in the diary for a fortnight. It’s a nice thing, something you were looking forward to. Then you wake up and your stomach’s already up to something, and you start doing the sums. How far is it. Where would you stop. How long could you sit there before you’d have to go. By the time you’ve finished the sums you’ve talked yourself out of it, and you’re relieved, and then about an hour later you’re not relieved at all, you’re just sad.

Here’s the part that doesn’t get talked about enough. Two people can have gut symptoms of roughly the same severity and lose very different amounts of their lives to them. A UK survey published this month looked at what makes that difference, and the answer is something you can actually practise.

This week’s research: the same symptoms, affecting lives differently

Researchers from Middlesex University London surveyed 395 adults in the United Kingdom who have fibromyalgia, which is a long-term condition of widespread pain and exhaustion. They recruited through UK fibromyalgia support groups and charities, and asked everyone about their gut as well as their pain.

Four in five of them had at least one disorder of gut-brain interaction, which is the family of conditions Irritable Bowel Syndrome (IBS) belongs to. IBS was by far the commonest one. So although the study set out to describe people with fibromyalgia, most of the people in it were living with a gut that behaves the way yours does.

Two findings matter for you. The first is the plain one: the worse somebody’s gut symptoms were, the lower their mood and the more their work, social life and daily activities were affected. Having several gut conditions at once was worse than having one. None of that will surprise you, but it’s useful to see it measured, because it puts a number on something people are often told they’re exaggerating.

The second finding is the interesting one. The researchers also measured something called psychological flexibility. Stripped of the jargon, it’s the ability to carry on doing what matters to you while an uncomfortable feeling is present, instead of waiting for the feeling to go first. People who scored higher on it had less depression and better daily functioning, and the link between their gut symptoms and the drag on their lives was weaker. Same symptoms, less life lost.

Be careful with what that does and doesn’t show. This is a survey taken at one moment in time, so it can’t tell you what causes what. It’s just as possible that having a less disrupted life makes you more flexible as the other way round. The gut diagnoses were what people reported about themselves rather than checks done by a doctor as part of the study. Nearly everybody in it was a woman and nearly everybody was white, and they were recruited through support groups, which usually means a more affected group than average. And the size of the buffering effect was small. Psychological flexibility explained roughly a tenth of the link between gut symptoms and low mood, not the whole thing. It’s one ingredient, not the answer.

The authors point to Acceptance and Commitment Therapy, a talking therapy built around exactly this skill, as a fitting next step for research. We’ve looked at neighbouring ground before, in What Shame Does To IBS, And How To Loosen Its Grip and in Can Gratitude And Purpose Really Calm IBS Symptoms?, which found something similar coming at it from the other direction.

Why a skill like this is important to your gut

IBS is understood as a disorder of gut-brain interaction. Your gut and your brain are in constant conversation, and in IBS that conversation has become oversensitive, so ordinary events in the gut arrive in the brain turned up loud. That’s a real, physical process, and it’s also a loop, which means what happens in one direction affects the other.

Waiting is what feeds the loop. You wait for a good gut day before you book anything. You wait to feel settled before you go. While you wait, your world gets a bit smaller, and a smaller world gives your attention less to do than watching your stomach. Your brain gets more practice at monitoring your gut, and monitoring makes sensations louder. That’s why a study about carrying on regardless isn’t a study about willpower. It’s a study about what you give your attention to, and attention is part of the mechanism.

This is where my own work sits. I’m a cognitive behavioural hypnotherapist, which means I use three things together on the same loop. Cognitive behavioural therapy works on what you expect a feeling in your gut to mean and what you do next because of it. Mindfulness trains your attention so you can notice a sensation as a sensation. Gut-directed hypnotherapy uses focused attention and imagery aimed at the gut itself. The British Society of Gastroenterology gives gut-directed hypnotherapy a strong recommendation for IBS, and NICE lists it as an option for IBS that hasn’t responded to first-line treatment after twelve months. I can’t tell you what any of it would do for your symptoms, and this week’s survey didn’t test a treatment at all. What it does suggest is that how much room your gut takes up in your life is a separate question from how bad your gut is, and the second question is the one you have more say over.

Your top tip this week

Pick one thing you’ve been putting off until your gut settles, shrink it, and do it this week anyway. Not the wedding, not the long drive. Choose the smallest real version: the coffee that’s fifteen minutes from home, the walk round the block, the phone call. Do it with the discomfort still there rather than waiting for it to clear, and decide in advance what you’ll do if your gut plays up, so that going isn’t a gamble. Afterwards, don’t judge it by how your stomach felt. Judge it by whether you did the thing. That’s the skill the survey was measuring, and it’s the part of this you can practise without an appointment.

The takeaway

Your symptoms and the size of your life aren’t the same measurement. This survey found that people who could keep going with what mattered to them while they were uncomfortable lost less of their lives to their gut, even with symptoms as bad as anybody else’s. It’s a small effect and an early finding, and it still points somewhere useful: not at controlling your gut, which nobody can promise you, but at how much of your week it gets to organise.

Wherever you are right now

If you haven’t had a firm diagnosis yet, start with your GP. Gut symptoms have several possible causes and some of them need ruling out, so get that done first. It also gives everything else you try a clear starting point.

If you were diagnosed a while ago and you’re still struggling, you’re exactly who the guidelines had in mind for psychological approaches. Try the one small postponed thing above this week, and notice how much of the deciding was about the symptom and how much was about the worry.

Hypnotherapy works alongside conventional medical care, never in place of it. This blog shares research for general information and is not a substitute for medical advice. Only a doctor can diagnose IBS. Always consult your GP or another relevant health professional. If your symptoms are new, changing, or accompanied by warning signs such as bleeding, unexplained weight loss, or persistent pain, please see your GP.
