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 Am I So Tired When My Blood Work Is Normal? What Standard Testing Misses
Normal labs and persistent symptoms is not a contradiction. The lesion is usually in a layer the standard panel does not measure. A Host Capacity Model reading of why conventional blood work returns normal while chronic illness continues, the specific cellular, mitochondrial, gut, and autonomic mechanisms involved, and what testing actually catches what is missed.

Why Does SIBO Keep Coming Back After Treatment?
Recurrent SIBO may represent an equilibrium state of an unaddressed host substrate failure. Antimicrobials reduce overgrowth without restoring the colonocyte bioenergetic capacity that defines which microbes can dominate. A Host Capacity Model reading of the recurrence cycle, the SLC5A8 / Fe-S / CD38-NAD+-SIRT3 mechanisms behind it, and what an HCM-anchored approach actually looks like.
