SIBOtest

SIBOtest SIBOTest.com provides fast, accurate, testing services in the diagnosis of SIBO and IBS. Normal stomach acid levels are required to kill bacteria.

Normally, bacteria are found in the trillions in the LARGE INTESTINE, where they perform various symbiotic functions for the human body. SIBO is a condition where bacterial overgrowth occurs in the absorptive area of the body—the SMALL INTESTINE. Symptoms of SIBO can include:
Diarrhoea
Constipation
Alternating constipation and diarrhoea
Abdominal cramping
Bloating and/or wind
Burping and Acid ref

lux/GORD
Food sensitivities
Joint pain
Skin rashes
Iron and B12 deficiency
Respiratory symptoms such as asthma
SIBO can occur when
The ileocecal valve (which connects the large and the small intestine) is dysfunctional, allowing large intestinal bacteria to migrate upwards into the small intestine where they wreak havoc. The normal cleansing wave of the small intestine is disrupted or stopped – this cleansing wave is called the Migrating Motor Complex (MMS), and occurs approximately every 90 minutes, typically between meals. The function of the MMC is to wash out accumulated bacteria and propel them toward the colon. The MMC is not related to the peristaltic waves of the large intestines. The result is bacteria are allowed to grow and proliferate throughout the small intestine (a little over 6 meters in length). SIBO causes damage to the absorptive surface of the small intestine - the ability of the body to absorb nutrients from food. The absorptive surface of the small intestine is likened to a shaggy carpet, with finger-like protrusions called villi. The surface of the villi contain microvilli which act as the interface of absorption—microvilli secrete enzymes called “brush border enzymes” which break starches into single molecules, proteins into single amino acids so these can be absorbed. SIBO can result in
Malabsorption of monosaccharides and amino acids (carbohydrates and proteins)
Fermentation of disaccharides by bacteria causing hydrogen, methane and hydrogen sulphate gasses
These gasses themselves are damaging to the gut wall
Malabsorption of vitamins (especially B12 and Folic acid)
Malabsorption of minerals (especially, magnesium, iron, and calcium SIBO can cause leaky gut, with a damaged gut wall allowing larger particles to pass through, causing an immune response. Causes of SIBO
Post infectious: a case of gastroenteritis can often be the “heralding event” for the development of SIBO
Overconsumption of simple carbohydrates
Medications: proton pump inhibitors, morphine and other opiates, narcotics, possibly beta agonists and calcium channel blockers
Stress: chronic stress can decrease stomach acid output (hypochlorhydria). Stress also causes changes in the motility of the small intestines, causing a pooling and stagnation which allows for bacterial overgrowth
Altered anatomy: malformation of the ileocecal valve, surgical intervention causing scarring and adhesions altering the normal anatomy of the small intestines
Initial colonization of bad bacteria: caesarean birth, no breast feeding. Associated conditions
Fibromyalgia and Chronic Fatigue Syndrome – especially associated with diarrhoea dominant SIBO
Chronic constipation – associated with methane-dominant SIBO
Irritable bowel syndrome (IBS)
Inflammatory Bowel disease (Crohn’s disease and ulcerative colitis)
Acid reflux
Coeliac disease
Interstitial Cystitis
Restless leg syndrome
Acne
Rosacea
Diabetes
Hypothyroidism
Scleroderma
Chronic Prostatitis
Non alcoholic Steatohepatitis (NASH)
Liver cirrhosis
Diverticulitis

When SIBO is suspected, where do you begin?

Without confirmation, treatment is based on an assumption.

Breath testing helps clarify what is present, guides direction, and provides a measurable baseline to reassess progress.

If SIBO is suspected, start with a SIBO breath test.

Interest in hydrogen sulphide SIBO has increased recently.

Hydrogen sulphide gas can be produced during bacterial fermentation in the gut, and certain symptoms are often attributed to it. However, these symptoms are not always specific and overlap with many other gastrointestinal conditions.

In Australia, standard breath testing measures hydrogen and methane.
While hydrogen sulphide is not directly measured, specific breath test patterns may raise clinical suspicion and require careful interpretation.

Breath testing should form part of a structured clinical assessment rather than being guided by symptom lists alone.

If SIBO is suspected, consider whether a SIBO breath test is appropriate.

“SIBO is not a real condition.”
“Breath testing is not accurate.”

These are still common statements patients and practitioners hear.

To help address some of the ongoing discussion around SIBO and SIBO breath testing, we’ve created a dedicated SIBO Research page that brings together published research, consensus guidelines, and scientific literature relating to SIBO and SIBO breath testing.

The page includes research on:
• The recognition and clinical relevance of SIBO
• Breath testing methodology and interpretation
• Limitations and considerations of SIBO breath testing
• Associations between SIBO and other diseases
• Current consensus guidelines and emerging research

The aim is not to overstate the evidence, but to provide a balanced, evidence-based resource that practitioners and patients can refer to when navigating the ongoing discussion around SIBO.

Chronic constipation can be complex, particularly when it does not respond to standard treatment strategies.

Methane has been associated with slower intestinal transit and is commonly observed in patients presenting with constipation. In these cases, assessing methane levels may help inform clinical decision-making and guide next steps.

Breath testing provides measurable data to support a more targeted and individualised approach.

When constipation persists, consider a SIBO breath test.

SIBO is often discussed as a single condition, but multiple gases may be involved.

Hydrogen and methane can influence each other, and symptoms alone do not reliably distinguish what may be contributing, particularly as they often overlap with other gastrointestinal conditions.

Without test data, it becomes harder to determine what is present or assess the response over time.

Effective management starts with accurate identification.

SIBO breath testing supports that process.

SIBO is one of those conditions that's easy to overlook, until you know exactly what you're looking for. 🔍

From classic gut symptoms to the subtle case history clues that often get missed, there's a lot more to the picture than bloating after meals.

Swipe through for the clues every practitioner should have on their radar — including the underlying drivers and associated conditions that may mean SIBO is the missing piece for your patient.

Because you might just be the practitioner who finally connects the dots. 🙌

If IBS doesn’t tell you why, what does?

A SIBO breath test gives you objective insight into what’s happening in the small intestine.

Specifically, it measures gases like hydrogen and methane produced by bacterial activity, which can indicate an overgrowth or imbalance in the small intestine.

This helps determine whether SIBO &/or IMO are present and if they are contributing to your symptoms.

It moves you from assumptions based on symptoms to something you can actually work from!

You’ve been told it’s IBS.

But what does that actually tell you?

That your gut is sensitive.
That your symptoms fit a pattern.

But not why it’s happening.

And that’s where people get stuck.

Because IBS is a diagnosis based on symptoms - not a cause.

In many cases, something is driving those symptoms beneath the surface.

SIBO is one of the most common.

In fact, studies suggest up to ~60–80% of IBS cases may involve SIBO.

If you don’t look for it, you won’t find it.

Testing answers that question.

A lot of gut conditions can look the same.

IBS, coeliac, IBD, food intolerances – they can all present with similar symptoms. And SIBO can sit underneath or alongside them.

That’s where people get stuck.

If you’re relying on symptoms alone, you’re guessing.

At some point, you need to know what you’re actually dealing with.

Testing gives you answers.
