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?

The Bile Acid–Estrogen Connection: A Missing Piece in Women’s Hormonal and Gut Health
One of the most interesting patterns I’ve been investigating through my work with women experiencing hormonal changes, gastrointestinal dysfunction, and complex chronic illness involves something that often receives very little attention

The Estrogen–Histamine Connection: Why I Look Beyond DAO and Histamine Levels
Something I frequently notice when working with clients experiencing histamine intolerance, mast cell-related symptoms, and chronic gastrointestinal dysfunction is elevated estradiol.

Zearalenone Mycotoxin, Beta-Glucuronidase, Estrogen Recycling, and Mast Cell Amplification
One of the mechanisms I have become increasingly interested in while working with complex clients is the way zearalenone exposure, intestinal microbial metabolism, estrogen handling, liver conjugation, cellular energy production, histamine

What May Be Driving PCOS? A Mechanistic Reading of Polycystic Ovary Syndrome
PCOS is not primarily ovarian. Gut dysbiosis, insulin resistance, estrobolome dysfunction, mitochondrial failure, and the CD38-NAD+-SIRT3 cascade drive the disease. Birth control and metformin contain the readout while the upstream mechanisms persist.

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.

Why Your Chronic Illness Got Dramatically Worse in Perimenopause: The Hormonal Cascade Driving Gut, Mast Cell, Brain Fog, and Fatigue Symptoms in Your 40s
What the research now shows about why women in their 40s experience the emergence or sudden worsening of MCAS, histamine intolerance, SIBO, autoimmune flares, and post viral illness, and where the actual upstream lesion lives.
