Preparing for your Sugar Malabsorption Breath Test

girl breath testingPrior to attending each breath test, there are a few requirements that need to be followed to ensure your test results are accurate:

4 weeks before tests:

  • Avoid undertaking any bowel preparation procedures (such as colonoscopy)

2 weeks before tests:

  • Avoid taking any antibiotics or probiotics (e.g., Yakult, Inner Health Plus) for 2 weeks prior or during your tests. If you have an illness that requires antibiotics, please notify us and we will postpone your tests.

A day before tests:

  • Avoid taking vitamins, minerals, laxatives or anti-diarrhoeal agents one full day before each test unless absolutely necessary.
  • You are required to follow the low FODMAP diet for 24 hours before your test. For a list of foods that are allowed on this diet please click on the link found on this webpage to download the patient information brochure.
  • For tests starting at 8am: You will need to fast from 8.00pm the night before. You can have water during this time.
  • For tests starting at 10am: You will need to fast from 10pm the night before. You can have water during this time.
  • For tests starting at 12noon: You can have a light breakfast before 7am with foods that are allowed on the diet.

On the morning of your tests:

  • It is recommended that medications are not taken for the period of the test. However, this matter should be discussed with your doctor first.
  • If it is absolutely necessary that you stay on your medications, tests can still be conducted but please inform the breath testing staff.
  • Anti-depressants and the contraceptive pill do not need to be ceased.
  • Each test will take 2-3 hours and need to be completed on separate days. There are some magazines and a television provided for entertainment.  Please also feel free to bring your own reading material or computer.
  • It is important to remember that a major purpose of breath testing is to assist a dietitian in individualising the low FODMAP diet (diet low in fermentable carbohydrates - fructose, lactose, fructans, GOS, sorbitol, mannitol) for functional gut symptoms. No matter what the results of the test, dietary advice is worth considering.

All of this information plus pre-test day diet food lists and tips can also be found in our breath testing brochure. Click here to download a brochure.

Test results will be sent to yourself and your referring practitioner (if you have one) after completion of ALL tests. This may take up to 10 working days.
