Xylitol Tolerance Test

What is Xylitol?

Xylitol is a naturally occurring sweet substance that can be found in some fruits, called a sugar alcohol.

It is commonly used in diet or sugar free varieties of lollies or mints and is sometimes used as a sweetener in chewing gum. A significant proportion of the population will experience gastrointestinal upset after consuming a large amount of xylitol.

If you are xylitol intolerant it means that your body is more sensitive to this substance and you may experience symptoms even after consuming a relatively small amount of xylitol.

Xylitol Intolerance 


Symptoms associated with xylitol intolerance may include:

  • increased gas
  • abdominal cramps and pains
  • bloating
  • diarrhoea
  • nausea


Testing for Xylitol Intolerance

Xylitol intolerance can be diagnosed via a simple breath test. This test involves xylitol being given as a solution in water to drink, with Hydrogen/Methane breath testing along with symptom monitoring being performed at regular intervals for 2-3 hours to determine intolerance.

Symptoms generally resolve once you remove the main sources of xylitol from your diet.
