The source behind the data
Real patient reports are structured into symptoms, tests, treatments, and outcomes, then aggregated into the data above.
Last reported: About 10 months of relief
IBS-D symptoms began in 2018 with diarrhea, bloating, gas, nausea, tenesmus, disrupted sleep, and low mood. Nutritionist-guided work eventually identified hydrogen-dominant SIBO. After three weeks on an elemental diet, the contributor reported a negative breath test and about 10 months of relief—an unusually durable stretch after years of symptoms.
Last reported: Improved over five months
After 30 years of daily stomach bloating and chronic constipation, the author improved their 100 ppm methane SIBO (IMO) over five months using herbal antimicrobials instead of further antibiotics, while managing Candida with diet, biofilm busters, and antifungal supplements.
Last reported: Symptoms noticeably eased
Severe bloating and brain fog continued despite five negative SIBO breath tests. The finding that changed the direction of the story came later, when capsule endoscopy revealed a biofilm in the ileum that standard testing had missed. Biofilm disruptors used with simethicone were then linked with noticeable symptom relief.
Last reported: Methane and symptoms reduced
After years of ineffective herbal antimicrobials, two antibiotic rounds combined with PHGG powder progressively lowered methane levels from high to low, reducing bloating and histamine symptoms while improving energy.
Last reported: Clear improvement reported
For 18 years, painful IBS-D and severe diarrhea persisted. A positive hydrogen breath test led to antibiotics, but the contributor reported no relief. The improvement came from a different direction: eliminating manufactured citric acid calmed the diarrhea, and vitamin B1 was linked with a further clear improvement.

Small subgroup
1 in 3
Among 51 breath-test-confirmed reports, PPIs were reported to make symptoms worse about one-third of the time. This small, self-reported pattern does not prove causation.
It measures gases in exhaled breath after a test sugar, commonly hydrogen and methane and sometimes hydrogen sulfide. The pattern and timing are interpreted using the lab’s protocol.
Yes. A negative result means the test did not meet the lab’s criteria. It does not explain every ongoing symptom, and test limitations or another condition may still matter.
No. It may inform the next clinical conversation, but patient-reported outcomes remain mixed even among the most common next steps.
Methane elevation is commonly described as intestinal methanogen overgrowth, or IMO, because methanogens are not bacteria. Use the terminology and criteria on the lab report.
No. GutPattern organizes patient-reported stories for comparison. It does not diagnose, prescribe, or recommend treatment.
