Abstract

Irritable bowel syndrome (IBS) is defined by abdominal pain and alterations in stool patterns. It is a common disease with a heavy burden on patients and providers. Pharmaceutical and psychiatric therapies have low success rates. A diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) has been suggested to treat symptoms of IBS by reducing consumption of poorly absorbed and indigestible carbohydrates. This decreases the amount of water in the bowel lumen and the amount of fermentable sugar available for colonic bacteria. Several recent randomized trials in patients treated for IBS with low-FODMAP diets have demonstrated improvements in IBS symptoms and stool characteristics. However, studies to date have had limitations, and the long-term efficacy and health impact of low-FODMAP diets is not known. Ongoing research will help address the benefits of low-FODMAP diets for IBS and other diseases.

FODMAP Basics

A FODMAP elimination diet is learning diet, not a permanent diet prescription. The object is to discover how changing certain sugars and fibers in your diet can help you manage your symptoms of gas, bloating, abdominal pain, diarrhea and/or constipation; the eventual goal is the most nutritious and varied diet you can tolerate. It may be right for you if you have irritable bowel syndrome (IBS) or a related condition and standard IBS therapy did not help.

The low-FODMAP diet can be tricky, since many kitchen staples and common food ingredients are off limits at first. It must be carefully planned to meet your nutrition needs. A registered dietitian nutritionist can help. This is especially important if you have other nutrition-related medical conditions.

FODMAP stands for fermentable oligo-, di-, and monosaccharides and polyols. FODMAPs are a group of poorly absorbed, fermentable carbohydrates that act together to produce gastrointestinal symptoms.
