Sorbitol Tolerance Test

What is Sorbitol intolerance?

Sorbitol is a sugar alcohol (polyol) commonly used as a sweetener in sugar-free sweets and chewing gum, diet and diabetic foods, amongst other products.

It is produced by the human body, occurs in fruit, beer and berries, is also contained in some medicines (e.g. mouth washes, cough syrups and laxatives) and cosmetics.

Absorption in the small intestine occurs passively and is much slower than other sugars. This allows even moderate doses to be malabsorbed, reaching the colon for fermentation, especially in individuals with a rapid intestinal transit.

Sorbitol Intolerance 


What are the symptoms of Sorbitol intolerance?

  • Bloating
  • Wind
  • Abdominal pain or cramping
  • Diarrhoea and/or constipation
  • Nausea
  • Reflux
  • Urgency
  • Can also be used for monitoring Coeliac disease management


Fructose and sorbitol intolerance often co-exist and mutually aggravate intestinal symptoms. The concurrence of lactose and sorbitol is less clear, although there is some supporting evidence.

Testing for Sorbitol Intolerance

Sorbitol is given as a solution in water to drink and Hyrdrogen/Methane breath testing along with symptom monitoring is performed at regular intervals for 2-3 hours to determine intolerance.

Sorbitol can also be used to monitor coeliac disease management and has been shown to be better than anti-endomyosial antibodies in revealing histological recovery in the follow-up of coeliac patients after the start of gluten-free diet due to its good correlation with histological damage.  It also appears to be able to detect dietary mistakes of patients on a gluten free diet according to a study by Tursi et al.1
