SIBO Testing in Suwanee, GA
Small intestinal bacterial overgrowth, or SIBO, happens when bacteria that normally live in the large intestine build up in the small intestine.
Understanding SIBO Testing
What Is SIBO?
Small intestinal bacterial overgrowth, or SIBO, happens when bacteria that normally live in the large intestine build up in the small intestine. Those bacteria ferment food before it can be absorbed, producing gas and the uncomfortable symptoms that come with it.
SIBO is often linked to something that slows the normal movement of the gut, such as prior abdominal surgery, certain medications, diabetes or other motility problems. Finding it, and finding why it happened, are both part of effective care.
Symptoms
Symptoms That Can Point to SIBO
SIBO symptoms overlap with several other conditions, which is why testing matters. Common symptoms include:
- Bloating that builds through the day
- Excess gas and abdominal discomfort
- Diarrhea, or in some patients constipation
- Feeling full quickly after eating
- In longer-standing cases, nutrient deficiencies or unintended weight loss
Many patients with SIBO have been told they have IBS. If that sounds familiar, our article on treating bloating and IBS explains how the two are told apart.
Diagnosis
How SIBO Breath Testing Works
SIBO is usually diagnosed with a breath test. After fasting, you drink a sugar solution, and you then provide breath samples at set intervals over about two to three hours. The samples are measured for hydrogen and methane, the gases bacteria produce when they ferment sugar.
A rise in those gases at the right time points to bacteria in the small intestine. The test is non-invasive, needs no sedation, and you can go about your day afterward.
Diagnosis
Preparing for the Test and What Comes Next
Preparation matters for an accurate result. You will typically follow a limited diet the day before and fast overnight. Recent antibiotics, probiotics and some medications can affect the result, so let the office know what you take. You will receive specific instructions to follow.
If the test is positive, treatment usually includes a targeted course of antibiotics, along with steps to address the underlying cause and reduce the chance of it coming back. Dr. Sumana Moole will review your results with you and build a plan around your symptoms.

After fasting, you drink a sugar solution and then breathe into collection tubes or bags at set intervals. The samples are measured for hydrogen and methane, the gases produced when bacteria in the small intestine ferment sugar.

The test usually takes about two to three hours. It is non-invasive and needs no sedation, so you can drive yourself and return to normal activities afterward.
How do I prepare for a SIBO breath test?
Most patients follow a limited diet the day before and fast overnight. Antibiotics, probiotics and some medications can affect the result, so share your full medication list with the office and follow the written instructions you receive.
Can SIBO cause bloating?
Yes. Bloating is one of the most common SIBO symptoms, because bacteria in the small intestine ferment food and produce gas. Bloating has many other causes too, which is why testing helps.
How is SIBO treated?
Treatment usually includes a targeted antibiotic course, along with steps to address what allowed the overgrowth, such as slow gut motility. Diet changes may help during recovery, and follow-up confirms the plan is working.
