"You Have a Bacterial Imbalance"
Someone has probably said that to you, quickly, on the way out of a consultation. It is one of those sentences that sounds like an explanation and explains nothing. What imbalance? Imbalance of what, against what, and why does it matter to your bowel at two in the morning?
Here is the specific version.
Three Findings That Actually Mean Something
Diversity collapses. A healthy gut carries an enormous variety of microbial species, and that variety is itself protective — it makes the community stable and hard to invade. In Crohn's, diversity is reduced. The community becomes narrower, less stable, and easier to dominate by the wrong organisms.
The butyrate producers disappear. This is the finding that matters most, and to understand why, you need one fact: the cells lining your colon do not primarily run on glucose from your blood. They run on butyrate, a short-chain fatty acid produced by specific gut bacteria when they ferment dietary fibre. Butyrate is the fuel of the gut lining. It also tightens the junctions between epithelial cells, supports the mucus layer, and calms local immune signalling.
In Crohn's, the main butyrate-producing species are depleted. So the lining is being starved of its own fuel by a bacterial community that no longer makes it. The barrier weakens, which lets more bacteria through, which drives more inflammation, which makes the environment more hostile to the very organisms that make butyrate. That is not an imbalance. It is a downward spiral with a mechanism.
Aggressive strains move in. In many people with Crohn's, adherent-invasive strains of E. coli are enriched. They are not ordinary passengers. They stick to the epithelium, invade it, and — crucially — survive inside the immune cells sent to destroy them. That gives you a persistent bacterial antigen sitting inside the bowel wall that the innate immune system cannot clear. Which is exactly the condition that produces the granulomas Crohn's is named for.
The Loop Feeds Itself
Crohn's changes the environment in ways that select for the wrong microbes:
- Inflammation itself favours them. Inflamed tissue releases oxygen and nitrogen compounds into the gut, and the resilient organisms that thrive in that environment tend to be the aggressive ones. The delicate anaerobes that make butyrate cannot tolerate it.
- Bile salt spillover. With an inflamed or resected terminal ileum, bile salts flood the colon and change the chemistry the community lives in.
- Diarrhoea washes out the slow growers. Rapid transit selects for fast-growing organisms and flushes out the slower, more beneficial anaerobes.
- A degraded mucus layer lets bacteria sit directly against the epithelium instead of at a distance.
So the microbiome is not simply an innocent bystander that got damaged. It becomes a driver in its own right — which is why treating the immune system alone leaves it running.
Why Antibiotics Give Relief and Then Cost You
Antibiotics can genuinely help in Crohn's, and there are situations — an abscess, perianal sepsis — where they are absolutely correct and you must take them. Do not refuse them.
But when antibiotics are used for the disease itself, this is what happens. They reduce the total bacterial load pressing on an inflamed wall, and symptoms ease. Then they finish. And the community that regrows is less diverse than before, poorer in the slow-growing butyrate producers that were most vulnerable, and more open to colonisation by resistant, aggressive organisms. The lining has lost more of its fuel supply. The substrate is worse than when you started, and the next relapse arrives on ground that is less defensible.
That is not a criticism of the doctor who prescribed them. It is a structural feature of what antibiotics do — and it explains why relief that is real can still leave you worse off over years.
What Root-Cause Correction Does
The microbiome is one arm of the gut driver system, and it is addressed within LIFES — but the order is everything.
- Phase L — Inflammatory Load Reduction (oral, 4–8 weeks). You cannot restore a microbial community into an inflamed environment. Inflammation is what selects against the organisms you want back. Lower the load first, and you change the terrain they have to grow in.
- Phase I — Internal Correction (oral, 8–16 weeks). This is the microbiome phase: rebuilding the epithelial barrier and the mucus layer while restoring the environment in which the beneficial community can re-establish, alongside immune recalibration.
- Phase F — Functional Clearance (oral, 6–12 weeks), only after L and I are stable — never at the start.
- Phase S — Remission Maintenance (tapered oral, 6–12 months), because a re-established community can be lost again.
All oral. There is no procedure and no clinic visit at any stage.
Why not simply take a probiotic and be done? Because seeding a garden tells you nothing about the soil. Organisms delivered into an inflamed lumen with a stripped mucus layer, high bile salt spillover and rapid transit largely pass through. The environment has to change first. That is the whole logic of doing L before I.
Honest Limits
Microbial restoration is slow, it is partial in people with extensive resection or altered anatomy, and it does not reverse scar. Keep your gastroenterologist, your medication and your monitoring — calprotectin, CRP, scopes. We work alongside them, and we will never ask you to stop a drug or skip a test.
Expect Recovery Stage 1 (weeks 1–4) to show as energy, sleep and digestion before stool frequency changes. The plateau at weeks 3–6 is expected and is not failure.
