Breath testing by Gastrolab


Guide to Dorevitch Gastrolab Breath Testing


Testing for food intolerances such as lactose intolerance and fructose malabsorption can be done via Breath testing

  • On site Breath Testing (a 2-3hour attendance may be required)1 Bruce street, Dandenong
  • Home Breath Testing kits are also available

So How does it work?

The test detects gas (either Hydrogen or Methane) that is produced from malabsorption. The unabsorbed carbohydrate is delivered to the colon, and fermented by gut bacteria. Hydrogen then dissolves into the blood, transported to the lungs, and is measured by the breath test.

Who is suitable for breath testing?

Patients with IBS (irritable bowel Syndrome) with suspected food intolerance to Lactose, Fructose, and Sorbitol are the best candidates. It also helps in diagnosing small intestinal bacterial overgrowth (SIBO) via a Glucose breath test.

Many patients with Gastrointestinal health issues can identify food as a trigger for their IBS symptoms. In IBS, true food allergies are uncommon; however food intolerance,
especially to especially to fermentable Carbohydrate known as FODMAPs is common. If breath testing is positive, a targeted and evidence-based exclusion diet can be implemented to manage IBS (irritable bowel Syndrome) symptoms. A low FODMAP diet supervised by one of our qualified dietitians can relieve IBS symptoms in up to 75% of IBS sufferers,
and patients typically respond within 1-2 weeks of initiation of the diet. Diarrhoea- and bloating-predominant IBS are the most likely subtypes to respond.

A low FODMAP diet is not intended to be a longterm strategy and gentle FODMAP re-introduction is encouraged, as a reduction in the microbiome load and diversity have been noted following long-term FODMAP exclusion.
