SIBO Breath Test for Bloating, Gas and Digestive Symptoms

At-home Genova 3-hour breath test with NuGeneLabs interpretation and gut roadmap included.

If you feel bloated after meals, deal with constant gas, swing between constipation and diarrhea, or react to foods that never used to bother you, SIBO may be one possible reason.

The Genova SIBO 3-Hour Breath Test is an at-home breath test that helps evaluate whether gas-producing microbes in the small intestine may be contributing to your digestive symptoms.

Your NuGeneLabs order includes the test kit, lab processing, provider-reviewed interpretation, and a practical gut roadmap, so you understand what your results may mean and what to do next.

Why Order Through NuGeneLabs?

A lab report can show numbers and a graph. NuGeneLabs helps turn those results into a practical plan.

Your interpretation summary reviews the full pattern, including symptoms, preparation quality, hydrogen and methane results, timing of gas changes, and next-step considerations.

The goal is not to guess which diet, probiotic, antimicrobial, digestive enzyme, or motility support product to try. The goal is to match your next step to your test pattern.

Who It’s For

This test may be a good fit if you experience:

• Bloating after meals
• Excessive gas

• Food-triggered digestive symptoms
• Symptoms that return after trying random gut supplements
• Suspected SIBO or methane-related digestive patterns

Why Bloating, Gas, Constipation, or Diarrhea May Need a SIBO Breath Test

Digestive symptoms are often treated with guesses: remove more foods, add probiotics, try enzymes, take antimicrobials, or start another cleanse.

However, bloating and gas can come from different patterns. Some people may have more of a hydrogen-type pattern. Others may have a methane-related pattern that is often discussed with constipation and slower transit. Some people may have symptoms even when the report is not simple or obvious.

A SIBO breath test helps bring structure to the next step by showing how your breath gases change after a lactulose challenge drink.

What the Genova SIBO Breath Test Checks

The Genova SIBO 3-Hour Breath Test measures breath gas patterns after you drink a lactulose solution.

Primary markers:

• Hydrogen: reviewed in relation to breath gas patterns that may be associated with bloating, gas, and diarrhea-type symptoms
• Methane: reviewed in relation to breath gas patterns that may be associated with constipation or slower motility
• Carbon dioxide: used by the lab to help review breath sample quality

Who Should Get Medical Guidance First

Speak with a healthcare professional before relying on this test if you have:

• Severe abdominal pain
• Unexplained weight loss
• Blood in the stool
• Persistent vomiting
• Fever or signs of acute infection
• Known inflammatory bowel disease, celiac disease, or another diagnosed GI condition
• Recent antibiotic, antifungal, antimicrobial, laxative, or colonoscopy-prep use
• Diabetes or blood sugar concerns
• Pregnancy
• Difficulty completing fasting or the preparation diet
• Known allergy or strong reaction to lactulose

This test is for functional wellness insight and should not replace medical evaluation when symptoms are severe, persistent, or concerning.
