What is a Low FODMAP Diet?

The Low FODMAP Diet is a specialized eating plan designed to help manage symptoms of Irritable Bowel Syndrome (IBS), functional gastrointestinal disorders and other gastrointestinal disorders. FODMAPs are a group of short-chain carbohydrates and sugar alcohols that are poorly absorbed in the small intestine and can cause gas, bloating, cramping, and diarrhea in sensitive individuals.

FODMAP stands for:

  • Fermentable
  • Oligosaccharides (fructans, galacto-oligosaccharides)
  • Disaccharides (lactose)
  • Monosaccharides (excess fructose)
  • And
  • Polyols (sorbitol, mannitol)
Low FODMAP Diet
Why It Matters

A Low FODMAP Diet helps reduce symptoms like bloating, gas, abdominal pain, and altered bowel habits (diarrhea or constipation) by limiting fermentable foods. Studies suggest that up to 70% of patients experience significant symptom relief compared to those following standard dietary advice.

How the Diet Works

  1. Elimination Phase (2–6 weeks): Remove all high-FODMAP foods to assess symptom improvement.
  2. Reintroduction Phase: Gradually reintroduce foods one group at a time to identify specific triggers.
  3. Maintenance Phase: Build a personalized diet based on tolerated foods.
