Fructose Malabsorption in Northern Norway
Fructose Malabsorption in Northern Norway. Fructose Malabsorption and Irritable Bowel Syndrome.

Different published studies has shown a possible co-variation between leakage of fructose to the great bowel and exacerbation of irritable bowel syndrome (IBS) symptoms.

The aim of the FINN trial is to study the role of fructose malabsorption in patients with IBS in order to evaluate different diagnostic criteria for fructose malabsorption and at the same time study the effect of diet treatment in this cohort of patients and estimate the prevalence of fructose malabsorption.
