What is a hydrogen breath test?

The test is based on breath Hydrogen analysis and provides information about the digestion of certain sugars or carbohydrates, e.g. milk sugar (lactose) or fruit sugar (fructose). The pattern and quantity of hydrogen produced in your exhaled breath at intervals during the test will help determine if you are intolerant to, or have difficulty in processing or absorbing certain sugars.

How does it work?

Hydrogen gas in the body is produced from intestinal bacteria. Bacteria, normally in the large intestine, produce hydrogen through fermentation of carbohydrates – such as lactose, fructose and other sugars. Some of the hydrogen produced by bacteria is absorbed by intestinal mucosa into the bloodstream and is transported to the lungs, where it can be detected in the breath.

Normally, such sugars are broken down and absorbed in the small intestine and very little reaches the large intestine to be fermented by bacteria. However, a number of adults develop a reduced ability to process and absorb certain sugars in the small intestine. They are therefore carried forward to the colon where they are metabolised by colonic bacteria producing a large amount of hydrogen that is measured in the breath.

What symptoms might I have to suggest a possible benefit from hydrogen breath testing?

There are a number of digestive symptoms which may arise from the malabsorption of sugars, and consequent production of excessive gas in the large bowel. These include:

  • bloating
  • wind
  • abdominal cramping
  • flatulence
  • rumbling
  • loose stools
  • nausea

Some people also report other symptoms, when they eat foods containing sugars which they are unable to digest. Some examples include:

  • headache
  • fatigue
  • restlessness or irritability
  • dizziness
  • cold or heat sensations/tingling

How is a hydrogen breath test done?

On arrival at the Centre, one of the staff will complete a brief questionnaire with you to check on your symptoms and that there is no problem in doing the test. You will then be asked to breathe out into a handheld device to collect the first breath hydrogen sample. After drinking the test sugar solution (e.g. lactose) further breath samples will be collected every 15 minutes for the next 2 hours, depending on the results or information required. You will be asked to rate your symptoms at the time of each breath sample and these answers will be documented.

How long does a hydrogen breath test take?

The test takes between 2 and 3 hours.

Are there any risks or side effects?

The test is very safe and, apart from the possible reproduction of some or all of your symptoms for a short time has no significant side effects or risks.

When do I get the results?

A full report, including symptom and breath hydrogen analysis and interpretation, will be sent to you and your doctor within one week of the test.

What does it mean if the test is positive?

This suggests that some or all of your digestive symptoms may be due to your being unable to process certain sugars adequately in the bowel.

What can be done if the test is positive?

If the test shows that you are unable to absorb certain sugars, you may benefit from a formal dietetic assessment and advice.
