Restrictive diets prescribed for SIBO often worsen gut health long-term by starving beneficial bacteria — the treatment becomes the disease

Bulsiewicz argues that the low-FODMAP and elemental diets commonly prescribed for SIBO reduce symptoms short-term but starve beneficial gut bacteria long-term. The dietary restriction creates an environment of reduced microbial diversity that perpetuates gut dysfunction.

SIBO is dramatically overdiagnosed because breath tests have high false-positive rates — many patients diagnosed with SIBO actually have other conditions

Bulsiewicz presents evidence that SIBO breath tests (the standard diagnostic) have false positive rates of 30-60%. Many patients told they have SIBO actually have IBS, food intolerances, or other conditions. The overdiagnosis leads to inappropriate antibiotic treatment.
