I Was Taking 6 Medications. The Root Cause Was in My Gut the Whole Time.

“I Was on Medication. My Inflammation Kept Rising. Here’s What the System Wasn’t Measuring.”

[OPENING HOOK — 0-15s] I did what the doctor said for over twenty years. Took the medication. Got the blood tests. And the inflammation just kept building quietly in the background the whole time.

[OPENING BRIDGE — 16-30s] Not because the GP got it wrong. Because the test she was looking at wasn’t measuring where the inflammation was actually coming from. And there’s a decent chance yours isn’t either.

I’m Neil. I’ve got NHS blood test records going back to 2012 and I’ve been off all my medication since February 2024. In the next ten minutes I’m going to show you how gut bacteria drive systemic inflammation — and why it shows up on your CRP long before your GP will ever mention it. This isn’t just my story. The same mechanism is running in anyone whose blood sugar, weight, or energy is going the wrong direction without a clear reason why.

[OPENING ROADMAP — 31-60s] We’re going to cover three things. First — what calprotectin is, and why it’s the one gut inflammation marker that’s almost never on a standard NHS panel. Second — what my numbers actually showed when I finally got it tested, and what changed when I started treating the gut directly. And third — the moment on Day 24 of my last extended fast when I put on a pair of Birkenstocks I hadn’t been able to wear in years. Because that’s when I understood this wasn’t about managing inflammation. It was about removing the source of it.

THE PUZZLE

For about ten years running a kitchen company, I could set my calendar by it.

Last working day before Christmas. Company winds down, everyone goes home, and I’d get a gout attack. Almost without fail. Two to four days, sometimes longer. Feet swelling up so bad I couldn’t get shoes on. Ankles like I’d borrowed someone else’s. Couldn’t walk. Genuinely couldn’t walk — not “a bit sore,” not “taking it easy.” Bed. Full stop.

And I was medicated the whole time this was happening. Allopurinol daily. And every December I’d get a private prescription for naproxen — or sometimes diclofenac, which carries a raised heart attack risk, and I took it anyway because the alternative was Christmas on the sofa unable to move.

I assumed it was the food. Rich Christmas stuff, a few more drinks. Fair enough theory. Except it wasn’t Christmas Day that triggered it. It was the last day of work. The moment the pressure stopped.

I thought about that for a long time. You take on stress for months, body holds it together, and then the moment you exhale — it falls apart. Seemed backwards. Shouldn’t relaxing be the thing that helps?

Took me years to understand what was actually happening. And it wasn’t the mince pies.

THE DATA

Let me take you to January 2025. Month eleven off all medication.

I’d had a full blood panel — WMTWL-EVID-103. CRP came back at 6.2 mg/L. Now, CRP is C-Reactive Protein. It’s your body’s inflammation marker. The NHS reference range says anything under 5 is normal. So 6.2 — technically elevated, but only just. “Borderline” is probably how most GPs would file it.

What nobody said to me, and what I had to go and read for myself, is that CRP as a cardiovascular risk marker operates on a different scale. Under 1 mg/L is genuinely low risk. One to three is moderate. Above three is elevated cardiovascular risk — independent of your cholesterol number. At 6.2, I wasn’t “just outside normal.” I was sitting in a risk bracket that mattered, and the result had landed in my inbox with no comment.

So I went back to the GP and asked about calprotectin.

Calprotectin is a protein released specifically by white blood cells when there’s active inflammation in the gut lining. It doesn’t measure systemic inflammation — cholesterol, blood sugar, the usual suspects. It measures what’s happening in the gut itself. And it’s almost never on a standard NHS panel unless you’re being investigated for something like Crohn’s or colitis.

My GP ordered it. Fair play to her — she didn’t need much convincing once I explained what I was tracking.

The result? It came back under 5. Which is optimal. Best possible reading.

And here’s where it gets interesting. Because on paper, that should have been good news. Gut inflammation: minimal. Systemic inflammation: elevated. They seemed to contradict each other.

They didn’t. They were telling me the same story from two different directions.

Between January and April 2025 I ran a gut protocol. Not complicated. Fermented foods every day — kimchi, kefir, sauerkraut. Significant fibre increase, whole foods, no takeaways, proper bread rather than the processed stuff. Still not perfect — I’ll be honest about that. But the direction was clear and I was consistent.

April 2025. Repeat blood panel — same WMTWL-EVID-103 evidence window.

CRP: 6.2 → 1.0 mg/L. An 84% reduction in three months.

And it wasn’t just the CRP. ALT — liver enzymes — dropped from 29 to 23. Lowest it’s ever been in my records. Bilirubin went from 12 to 9 — a 25% improvement. HbA1c held steady at 37. All of it moving the same direction, at the same time.

That’s not four things improving independently. That’s one upstream problem reducing, and everything downstream following.

Tim Spector — gut researcher, ZOE co-founder — has cited a Stanford trial where people eating five portions of fermented foods daily saw significant decreases in 19 inflammatory proteins in just a few weeks. Nineteen. Not one marker, not two. Nineteen simultaneously. When you see multiple markers improve together that fast, it’s not coincidence. It’s a common root.

THE INSIGHT

So — back to the Christmas gout.

The stress of running a company through December wasn’t just in my head. It was in my gut. Cortisol — your primary stress hormone — suppresses the protective mucus layer in your gut lining. Do that for long enough, repeatedly, year after year, and the barrier starts to fail.

Prof. Janet Lord — she researches inflammation and ageing at the University of Birmingham — described the mechanism like this. Your gut microbiome helps generate the mucus lining that keeps the gut contents where they’re supposed to be. As diversity declines — through stress, UPF, age — you get more pathobionts. Unhelpful bacteria. They increase the chance the gut becomes leaky. Bacteria get into the bloodstream. The immune system sees them as a threat. And there’s inflammation.

The bouncer goes mental.

Which is where ANA-020 earns its place. Your gut lining is like the cellar door in a pub — between the cellar, where everything’s stored, and the bar upstairs, where it should be served properly. When the cellar door’s intact, the right things come up in the right way. When it’s cracked and leaking, you’ve got beer seeping through the floorboards, rats getting upstairs, the whole bar smelling of damp. The bouncer — your immune system — is going constantly. Not because there’s one big problem. Because the door’s been broken for years and stuff keeps getting through.

That’s chronic low-grade inflammation. Not a flare. Not a crisis. A constant low hum.

And the gout? Uric acid crystal formation is driven partly by inflammatory state. I was managing uric acid with allopurinol. But the gut was feeding the fire that made the crystals worse. Every December, a month of stress degrading the gut lining, cortisol suppressing the protective barrier — and then the moment I relaxed, the inflammation that had been building released. The gout was downstream. The gut was upstream. I was medicating the river, not the source.

The calprotectin result under 5 told me the gut lining was healing. The CRP dropping 84% told me the systemic consequence was resolving. They weren’t contradictory. The calprotectin was showing me the cause was addressed. The CRP was showing me the effect was following.

In my case, N=1, I can’t say this is what’s happening in your body. What I can say is that I had thirteen years of increasing medication load and a CRP that nobody mentioned — and that when I started treating the gut directly, more things improved simultaneously than any single medication ever managed.

THE LESSON

What I’d do differently:

I’d have asked about CRP as a cardiovascular risk marker — not just “is it normal” — a decade earlier. The difference between “6.2, just outside range” and “6.2, which puts you in the elevated cardiovascular risk bracket” is enormous. I didn’t know to ask the right question. I do now.

And I’d have asked for calprotectin earlier. It’s not a standard test. You have to know it exists to ask for it. It’s not expensive, it’s not invasive, and it tells you something your standard panel doesn’t. If you’ve got unexplained inflammation, chronic conditions, energy that doesn’t match your bloodwork — it’s worth asking your GP about.

What to watch for — if you’re already tracking:

If you’ve got elevated CRP that isn’t shifting despite diet changes, or multiple conditions that don’t seem to respond to their individual medications the way they should — the gut is worth investigating. Not because the conditions aren’t real. Because the root they share might not be getting measured.

The early warning signal — if you’re noticing things without a diagnosis yet:

Here’s what I’d say to the version of me that hadn’t been told anything was wrong yet. Chronic low-grade inflammation tends to start years before it gets a name. It shows up as energy that’s consistently a bit flat. Joints that are a bit achy without a clear reason. Conditions that don’t seem serious individually but cluster together. The body doesn’t usually go from fine to broken overnight. It grumbles first.

The mechanism connecting all of it — the gut driving the immune system driving the inflammatory load — is the same process whether you’re medicated or not, whether you’ve had a diagnosis or you’re just noticing something feels off. It starts quietly, long before any GP puts a label on it. That’s worth knowing.

CTA + SAFETY

If you want to start tracking your own inflammation markers — CRP, and potentially calprotectin if your GP agrees it’s warranted — I’ve put a simple guide to what to ask for and how to interpret the numbers in the description below. Not a protocol, not a prescription. Just the questions I wish I’d known to ask a decade ago.
