The limits are published alongside the reasoning.
- Evidence tiers
Every article carries an explicit evidence tier, so established biology is never presented as if it were clinical proof.
Read the claim ledger - What this does not prove
Mechanistic pieces are required to state their own limits and the competing explanations that would fit the same data.
See the counterarguments - Published corrections
Where the reasoning has been revised, the revision is recorded rather than quietly edited away.

- Why does my SIBO keep coming back?
- Are SIBO breath tests actually reliable?
- Why don't antihistamines settle my symptoms?
- Can I have mast cell activation with normal tryptase?
- Why won't my Long COVID symptoms resolve?
- Why did COVID trigger this in me and not others?
- Why are my labs normal when I feel terrible?
- Why doesn't my stool test match my symptoms?
- Why does every protocol stop working after two weeks?
- Why did butyrate or probiotics make me worse?
- What do bile acids have to do with my gut symptoms?
- Can gut health affect my hormones and egg quality?

Why SIBO Keeps Coming Back: MMP-9, EMT, and the Collapse of Host Capacity
Chronic intestinal inflammation can change the identity and metabolism of the epithelial cell itself. A mechanistic reading of MMP-9, E-cadherin, beta-catenin and epithelial-to-mesenchymal transition, and why that shift can keep reselecting the microbial pattern behind recurrent SIBO.

Your Mast Cells May Be Reacting to a Gut That Never Stopped Signaling Danger
Mast cells rarely become reactive without an input. A short reading of the gut-derived signalling that keeps them primed, and why that reframes mast-cell symptoms as downstream rather than primary.

Why Does Endometriosis Come Back After Surgery? The Gut, Estrobolome, and Bioenergetic Mechanism
Endometriosis recurs because excision removes lesions but not the substrate that selected for them. A mechanistic reading of the gut estrobolome, beta-glucuronidase-driven estrogen recirculation, LPS-driven inflammation, pelvic mast cell infiltration, mitochondrial dysfunction, and iron-driven oxidative damage — and why surgery and hormonal suppression contain the disease but rarely resolve it.

How Dysbiosis Disrupts Hormonal Health, Ovulation, and Egg Quality From the Inside Out
The fertility conversation has become overwhelmingly hormone-centric, but one of the most important mechanistic layers is still being underappreciated: the inflammatory dialogue between the gut microbiome and the ovary itself.

The Epigenetic Truth About Why Your Mast Cells Won’t Calm Down (And How to Actually Fix It)
I ve spent months buried in research that keeps pointing to the same uncomfortable conclusion: we ve been treating mast cell activation syndrome at the wrong level.
