Overview
Previous studies have shown that stool transplantation (FMT) have positive effect in symptoms for some patients with irritable bowel syndrome (IBS). Studies have shown that it is possible by FMT to reverse the microbiome of the recipient's intestine in the direction of the microbiome of the donor. The effect on eating habits for engraftment of microbiome by FMT is unknown.
The purpose of this study is to investigate whether FMT relieves FODMAP diet extension without worsening intestinal symptoms in IBS patients.
