Does the app diagnose SIBO?

No. SIBO is diagnosed by breath test or clinical judgement. The app tracks symptoms and treatment response.

Can I track multiple treatment rounds?

Yes - that's a core feature. Each round becomes a comparable phase in the insights screen.

Does it support the bi-phasic diet?

Yes. Tag meals by phase (phase 1 / phase 2 / reintroduction).

What if my SIBO is methane-dominant (IMO)?

The app handles both. Methane is more associated with constipation, hydrogen with diarrhoea or bloating.

For SIBO and IMO

SIBO is a long road. Bring data to every appointment.

Small intestinal bacterial overgrowth (and intestinal methanogen overgrowth) often takes multiple treatment rounds. A Gut Day tracks symptoms, treatments and food responses across months - so you and your doctor can see what actually moved the needle.

Why SIBO is hard to track manually

SIBO treatment cycles are long: rifaximin courses, herbal protocols, prokinetics, low-FODMAP / SCD / bi-phasic diets - each tested over weeks or months. By month three, no one remembers if symptoms in week two of cycle one were better or worse than week two of cycle three. A Gut Day stamps every entry with active treatment and diet so months-later comparisons are honest.

How A Gut Day helps

Built for this exact problem

Treatment phase tracking

Tag each day with active treatment (rifaximin, herbal, prokinetic, none). Insights group by phase.

Multiple rifaximin cycles
Herbal protocol logs
Prokinetic timing

Hydrogen vs methane symptoms

Different overgrowths produce different patterns. Tag bloating, urgency, constipation separately.

Per-symptom severity
Daily symptom mean
Trend over months

Bi-phasic / SCD / low-FODMAP support

Tag meals by current SIBO diet phase. The app respects the protocol when ranking triggers.

Breath-test result log

Record SIBO breath test results (lactulose / glucose) over time to see treatment response.

How it works for SIBO

1
Set your current treatment
Pick from rifaximin, herbal, prokinetic only or off-treatment.
2
Log meals + symptoms daily
Bloating after eating is the cardinal SIBO signal - track it carefully.
3
Tag protocol changes
When you start or stop a treatment, mark the date.
4
Bring the trend graph to your appointment
One screenshot shows months of progress (or lack thereof).

Why bloating-after-eating is the SIBO signal

In SIBO, bacteria in the small intestine ferment food before your body absorbs it - producing hydrogen (or methane) gas within 30-90 minutes of a meal. The classic pattern: 'I look 6 months pregnant by 3pm, regardless of what I eat.'

A Gut Day tracks bloating timing relative to meals, so you can see the curve. Treatment that works flattens the curve. Treatment that doesn't, doesn't.

Relapse tracking is half the battle

30-50% of SIBO cases relapse within a year. Catching relapse early - before it's full-blown - is much easier with a 6-month symptom baseline. A Gut Day's monthly trend graph makes early relapse obvious.
