What is the Low-FODMAP Diet?

  • FODMAP refers to a group of five sugars found in certain foods. These sugars are lactose, fructose (in excess), fructans, galactans and polyols. Specifically, FODMAP stands for:
  • Fermentable
  • Oligosaccharides
  • Disaccharides
  • Monosaccharides
  • And
  • Polyols

For some people, FODMAPs are poorly absorbed. When this happens, symptoms may include:

  • Bloating or swelling in your belly.
  • Gas.
  • Belly pain.
  • Nausea.
  • Diarrhea (loose stool).
  • Constipation (hard stool or trouble passing stool).
  • The low-FODMAP diet has two phases, eliminating and then reintroducing FODMAP sugars. This helps you figure out which sugars cause symptoms at what amount.
  • It is very important to work with your doctor or dietitian when thinking about following the low-FODMAP diet.
  • Do not start the low-FODMAP diet until your doctor or dietitian tells you to and gives you detailed instructions on how to follow the diet the right way.
