Irritable Bowel Syndrome and Low FODMAP Diet

Does Irritable Bowel Syndrome Improved by Low FODMAP Diet ?

The patients having a syndrome SII would be more intolerant in the fructose than the healthy subjects and would benefit from a fructose diet but also from the fructans which contain some fructose. The intolerance in the fructose is diagnosed thanks to a respiratory test after absorption of fructose. However, the eviction of the fructose is sometimes recommended to the patients without having realized beforehand the test of intolerance.

The main objective is to evaluate the efficacy of the FODMAPS diet on IBS symptoms and to correlate the results with the respiratory test
