How to Repair a
Leaky Gut

Why People Look to Find Out How To Repair a Leaky Gut

Most people don’t come across this term by accident. They come to it after months, sometimes years, of bloating, fatigue, skin flare-ups, food reactions, joint aches, or brain fog that doctors haven’t been able to explain, or have put down to stress. If that sounds familiar, you are not imagining it, and you are not alone. A lot of people I work with have been told their bloodwork is “normal” while they still feel far from well, and that gap between how you feel and what the standard tests show is often exactly where gut health comes in. Taking those symptoms seriously, rather than dismissing them, is usually the first real step towards understanding what’s actually going on.

Is Leaky Gut a Serious Condition?

It’s a fair question, and one I’m asked often. Intestinal permeability is a genuine, studied physiological process, though the term “leaky gut” itself is more commonly used in nutritional therapy and functional medicine than in conventional practice. That doesn’t make the underlying experience any less real. What it means in practice is that your gut and your wider health are more connected than a lot of standard care accounts for, and looking at gut function is a reasonable, evidence-informed place to start when symptoms don’t add up.

A Root Cause Approach

There is no single supplement or seven-day plan that will repair a leaky gut on its own, and I would be doing you a disservice if I told you otherwise. What actually helps is working out which of the contributors above apply to you and building a personalised plan around that.

This might involve looking at your current diet, your stress levels, your sleep, and, in some cases, functional testing to get a clearer picture of what’s happening in your gut. From there, we build a realistic, step-by-step plan to support your gut lining and calm the immune response that’s been keeping you unwell.

It’s not instant, and I won’t pretend otherwise. Most people notice gradual change over weeks and months, not days, because you’re supporting a real process, not masking symptoms with something that wears off.

Practical Steps

While a personalised plan will always work better than generic advice, some general principles tend to support efforts to repair a leaky gut for most people.

Increasing the variety of plants in your diet, not just the amount, feeds a wider range of beneficial bacteria in your microbiome. Reducing ultra-processed food, where it’s realistic to do so, takes some of the burden off your gut. Managing stress, even in small, consistent ways, matters more than most people expect, given how closely stress and gut function are linked. Introducing fermented foods gradually, rather than all at once, also tends to sit better with a gut that’s already under strain.

None of this replaces working out your individual root cause, but it’s a sensible, low-risk place to start while you consider more personalised support.
