Low FODMAP Diet for IBS: What to Eat and How It Helps

1. What Is the Low FODMAP Diet?

Ever feel like your gut is constantly in protest? The Low FODMAP Diet was created to help people with IBS (Irritable Bowel Syndrome) and SIBO (Small Intestinal Bacterial Overgrowth) get relief from bloating, gas, and stomach cramps.

FODMAP stands for:

  • Fermentable

  • Oligosaccharides (like onions, garlic)

  • Disaccharides (like lactose)

  • Monosaccharides (excess fructose)

  • And

  • Polyols (like sorbitol, mannitol)

These carbs ferment in your gut and cause symptoms. Cutting them out—even temporarily—can offer serious relief.


2. Who Should Consider It?

You might want to try this diet if:

  • You're constantly bloated

  • You feel pain or discomfort after meals

  • You deal with unpredictable trips to the bathroom

  • You've been diagnosed with IBS or SIBO

If that sounds like you, talk to your doctor or a registered dietitian first.


3. How It Works: Three Phases

1. Elimination Phase (2–6 weeks)

Remove all high-FODMAP foods. It’s strict but temporary.

2. Reintroduction Phase

Add FODMAP groups back, one by one, and track how your body reacts.

3. Maintenance Phase

Eat a customized, balanced diet based on what works for you.
