One of the most common things I hear from people partway through treatment is some version of this: "I cleared my SIBO on the test but I still don't feel well. Did it even work?"

Or the opposite: "I've been doing everything right for months and I still have symptoms. Maybe nothing is ever going to work for me."

Both of these come from the same place. A picture in your head of what healing is supposed to look like, and a reality that doesn't quite match it. And when those two things don't line up, it's easy to assume something has gone wrong.

So I want to talk about what healing from SIBO actually looks like in practice, because I think it's one of the most misunderstood parts of this whole journey.

A Negative Test Is a Milestone, Not the Finish Line

Let's start here because I think this is where a lot of confusion comes from.

Clearing SIBO on a breath test is genuinely something to celebrate. It means the treatment worked, the overgrowth is gone, and your body responded. That matters.

But the test result is a milestone, not the finish line. By the time SIBO has developed and been present for any length of time, it has caused changes in the digestive system that don't resolve the moment the bacteria are cleared. The gut lining may be compromised. The microbiome needs rebuilding. Motility may still be sluggish. Nutrient absorption has likely been affected. Digestive enzyme output may need support.

All of those things take time to repair, and they need active support to do so. This is why people can test negative and still feel unwell, sometimes for quite a while afterwards. It doesn't mean the treatment failed. It means there's more work to do, and that work is just as important as the treatment itself.

I know this from my own experience. I was diagnosed with hydrogen SIBO in 2016 after years of symptoms I hadn't been able to make sense of. I did six weeks of herbal antimicrobials, along with enzymes and gut support, and when I finished I still felt the same. I was really disappointed, convinced the treatment hadn't worked.

But I decided to retest before giving up, to use myself as a case study and at least see what progress had been made. I had actually already bought all the supplements I needed to do a second round and was getting ready to start. When the results came back, the SIBO had cleared completely in that one round. I'm so glad I retested before launching into more treatment, because the problem was no longer a small intestine overgrowth issue. It was something else entirely, and treating it as if it were SIBO would have been the wrong move.

The lesson there is important: always retest before retreating [Blog post: Is It SIBO or Something Else?]. What you're dealing with after treatment may be quite different from what you started with.

After clearing, I made the classic mistake of reintroducing foods too quickly. After being so restricted for so long, I overdid it. My body wasn't ready, and I paid for it. I also went through a stressful period of moving countries and starting a new business, and stress was affecting things more than I appreciated at the time.

What eventually made the difference was being systematic. Planning meals. Introducing foods in a specific order and in specific amounts. Focusing on rebuilding the microbiome. And giving it enough time. SIBO has been gone ever since. I even retested a few years later just to check, and it was still clear.

Had I not understood that clearing the overgrowth was just one part of the process, I could easily have concluded that something had gone wrong, or that the treatment hadn't worked, or that SIBO had come back. It hadn't. I was just still healing.

Healing Is Rarely a Straight Line

This is probably the most important thing I can tell you about the healing process: it is not linear.

There will be good days and harder days. There will be weeks where you feel like you're making real progress, and then a day where symptoms flare and it feels like you're back to square one. That flare doesn't necessarily mean you've relapsed. It might mean you pushed too hard too soon with food reintroduction, or you had a stressful week, or your body is just moving through a phase of the healing process that feels uncomfortable before it feels better.

Progress in gut healing tends to show up in small, quiet ways before the big shifts happen. Your bloating is a six instead of a nine. You had three good days in a row. You ate something you couldn't tolerate last month and you were fine. You got through a full day without thinking about your gut once.

These are the signs that matter. They don't always feel dramatic, but they're real, and they add up.

The Stages of Healing

One of the reasons healing from SIBO takes the time it takes is that there are distinct phases, and each one matters.

The first is preparation. Before we even start treating the overgrowth, we work to prepare the body. Supporting digestion, calming inflammation, and creating the right conditions for treatment to be effective. Most protocols skip this entirely, which is one of the reasons results don't hold [LINK TO: Why Your Gut Isn't Healing Even Though You're Doing Everything Right].

Then comes treatment itself, addressing the overgrowth with targeted antimicrobials based on what the breath test has shown.

After that comes rebuilding. This is the phase that gets skipped most often, and it's one of the main reasons SIBO comes back [LINK TO: Why SIBO Keeps Coming Back]. Once the overgrowth has been cleared, the gut environment needs to be actively restored. The microbiome needs to be repopulated. The gut lining needs support. Motility needs to be addressed if it was part of the picture. Food tolerance needs to be gradually expanded rather than staying restricted indefinitely [LINK TO: Why the Low FODMAP Diet Isn't Fixing Your Bloating].

And then there's the longer term work of maintaining gut health, continuing to expand food tolerance, addressing any remaining root causes, and making sure the conditions that allowed SIBO to develop in the first place have actually changed.

Skipping or rushing any of these stages is one of the main reasons people end up cycling back through treatment without ever fully getting better.

Our three month Gut Restoration Program is built around exactly these stages. We work through preparation, treatment, and rebuilding in a structured sequence, tailored to each person, so that nothing gets skipped and results actually hold.

Signs You Are Actually Healing

Sometimes healing is happening even when it doesn't feel like it. A few things worth paying attention to:

Your bloating is less severe, even if it's still present. You're tolerating foods you couldn't a few months ago. Your energy is more stable through the day rather than crashing after meals. Bowel movements are becoming more regular and more comfortable. Brain fog is starting to lift. You're spending less of your day thinking about your gut.

None of these might feel like much on their own. But if you look back three months and several of these things are true, that's healing. That's your body doing what it's meant to do when it's being supported properly.

What Gets in the Way of Healing

In my experience, there are a handful of things that consistently slow healing down or interrupt it.

Expecting too much too soon is a big one. SIBO doesn't develop overnight, and it doesn't resolve overnight either. When progress feels slow, the temptation is to jump to the next protocol, try a different supplement, or change the approach entirely. But constantly changing course is one of the things that keeps people stuck. Sometimes the most important thing you can do is stay the course and give the process enough time to work.

Not doing the rebuilding phase after treatment is another. Finishing antimicrobials and then just going back to normal life without actively supporting the recovery of the gut environment is a missed step that makes relapse much more likely.

And then there's stress. Chronic stress affects gut motility, gut lining integrity, and the nervous system signals that coordinate digestion. If stress isn't being addressed alongside everything else, it will keep undermining progress. This is why we look at the whole picture, not just the gut in isolation.

What Full Healing Can Look Like

I want to end this with something that I hope feels genuinely encouraging rather than like a sales pitch, because I mean it sincerely.

Full healing is possible. I know because I've been there myself, and I've watched hundreds of clients get there too.

Today I eat whatever I want. I order anything on a menu. I travel without planning my entire trip around food. I go to friends' houses and eat whatever they put in front of me. I don't think about my gut during the day. For a long time my digestion was like a dark cloud that organised everything else around it. Now it just isn't something I think about much at all.

I also want to be honest that my digestion is still something I nurture. I'm a sensitive person, and I notice when stress or poor habits start to catch up with me. I think of certain foods the way I think about alcohol, fine sometimes, not something I want to have every day. But I can have all foods. I don't have fear around eating anymore. And that freedom, to just be present at a meal, to travel, to go out with friends without the mental load of planning around symptoms, is one of the things I'm most grateful for.

I also see this with clients regularly. People who came to us having been unwell for years, having tried multiple things without success, who now live their lives without their gut being the thing that organises everything else around it. They eat out. They travel. They wear the clothes they want to wear. They have the energy to show up for their families and their work and the things they love.

That is what healing looks like. And it doesn't require perfection or a lifetime of restriction. It requires the right approach, done in the right order, with enough time and support to actually work.

If You're Not Sure Where You're At

If you're partway through treatment and wondering whether you're on the right track, or if you've finished treatment and still don't feel well, it's worth having a proper conversation about what's going on and what might need to happen next.

That's exactly what our Discovery Calls are for. We'll go through where you're at, what you've already done, and what the path forward might look like for your specific case.
