SIBO Testing

Understanding the Hidden Drivers of Gut Symptoms

Many people live with ongoing digestive symptoms such as bloating, abdominal discomfort, excessive gas, diarrhoea, constipation, or symptoms commonly labelled as Irritable Bowel Syndrome (IBS). Despite trying dietary changes or treatments, they may still struggle to understand what is causing their symptoms.

In some cases, Small Intestinal Bacterial Overgrowth (SIBO) may be a contributing factor.

At Witcombe Health Private GP Practice, we offer SIBO breath testing as part of a personalised approach to investigating digestive symptoms and gaining a deeper understanding of your gut health.

What is SIBO?

Small Intestinal Bacterial Overgrowth (SIBO) occurs when excessive numbers of bacteria are present in the small intestine.

Normally, most gut bacteria are found within the large intestine. When bacteria accumulate in the small intestine, they can begin fermenting food too early in the digestive process. This may lead to increased gas production and a range of uncomfortable digestive symptoms.

SIBO has become increasingly recognised as a potential underlying factor in people experiencing persistent digestive problems, particularly those with symptoms resembling IBS.

Common Symptoms of SIBO

SIBO can present differently from person to person, but common symptoms include:

• Bloating, especially after eating
• Abdominal pain or discomfort
• Excessive wind or gas
• Diarrhoea
• Constipation
• Alternating diarrhoea and constipation
• Distension of the abdomen
• Nausea
• Food sensitivities
• Feeling excessively full after meals

If you experience ongoing digestive symptoms that are affecting your quality of life, SIBO testing may help identify whether bacterial overgrowth could be contributing to your symptoms.

What is a SIBO Breath Test?

A SIBO breath test is a non-invasive investigation used to assess for bacterial overgrowth within the small intestine.

The test involves drinking a specially prepared solution and providing breath samples at set intervals. These samples measure gases such as:

• Hydrogen
• Methane

Elevated levels of these gases may suggest bacterial fermentation occurring within the small intestine.

The results can provide valuable information to help guide the next steps in your personalised treatment and management plan.

Who May Benefit from SIBO Testing?

SIBO testing may be considered for individuals experiencing:

• Persistent bloating
• IBS-type symptoms
• Unexplained digestive discomfort
• Chronic gas and abdominal distension
• Ongoing diarrhoea or constipation
• Recurrent digestive symptoms despite dietary changes
• Suspected gut microbiome imbalances

Our experienced clinicians will assess your symptoms and medical history to determine whether SIBO testing may be appropriate for you.
