No consults to sell. No supplement line.

Is it SIBO, or something that looks like it?

You have read six confident articles that contradicted each other. That is not your fault, and it is not because you missed something. The diagnostics in this area are genuinely contested, the two common breath tests agree with each other less than you would believe, and almost everyone ranking for these questions is selling a consultation or their own supplements.

We sell neither, which is the only reason we can afford to tell you which parts are actually unsettled.

Three things the confident articles leave out

5 of 6

recommendations in the main clinical guideline rest on evidence its own authors grade as very low quality

All six are conditional. Clinical guideline

8.7%

agreement between the two common breath tests, on the same patients

A positive on one and a negative on the other is routine, not a lab error. Peer-reviewed study

1 of 5

breath tests can physically detect hydrogen sulfide

The other 4 cannot, so a negative from one does not rule it out.

Specialists are currently arguing about whether the main test should be used for this at all. We are not going to pretend to settle that for you. We will tell you it is happening, show you both positions, and label every source with how strong it actually is.

Start with what you are actually trying to tell apart

Nine conditions overlap here, which makes 36 possible pairs. Most sites cover the pairs that suit their product. We measured all 36 against what patients actually discuss together, and wrote about the ones that are genuinely confused.

All 36 pairs, including the ones we chose not to write about

The mistake that costs people the most money

Someone suspects overgrowth, buys the cheaper two gas test, gets a negative, and concludes the question is settled. It is not settled. It is unmeasured, because that test cannot detect hydrogen sulfide at all. Those are different things, and almost nothing on the internet explains the difference before you have paid.

What each test measures, with prices and the date each was checked

Why you should believe any of this

Every source we cite carries a label saying how strong it is, so a conference abstract never reads like a clinical guideline. Every price shows the date we checked it. And when we say patients confuse two conditions, that comes from counting 7,205,554 comments across 18 patient communities rather than from a keyword tool. We publish the query behind every count, and the dataset is public, so you can check us instead of trusting us.

The corpus695,050 posts and 7,205,554 comments. Every query we publish, and every limitation.How we workHow we compare, verify and update. What we will never publish.

We are not clinicians, and we say so on a whole page about it. In a field where everyone implying clinical authority is also selling clinical services, that seemed worth being plain about.
