FODMAP – FODMAP: When this diet helps with bloating

In short: FODMAPs are certain carbohydrates that can ferment in the gut. A low-FODMAP diet can help with bloating and IBS – but only for a while, and ideally with guidance.

What are FODMAPs?

FODMAP stands for “Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols” – in other words, different types of carbohydrates.

These “sugars” are normally absorbed in the small intestine. When it reaches its limits, they move on to the large intestine, where gut bacteria ferment them. You notice the resulting gas as bloating, abdominal pain and sometimes diarrhoea.

When can a low-FODMAP diet help?

With recurring bloating, abdominal pain or diarrhoea – and often with IBS – it's worth trying a low-FODMAP diet for a while to see whether your symptoms improve.

The three phases

1. Elimination: for a few weeks, high-FODMAP foods are strongly reduced.
2. Reintroduction: individual groups are tested step by step.
3. Personalisation: you only avoid what you really don't tolerate.

Why only for a while?

FODMAPs aren't essential, but they matter: many of them feed the beneficial gut bacteria. That's why the diet should only be used therapeutically and not kept forever – consciously, gently and ideally with professional guidance.

What else can help

• Body therapies such as foot reflexology to support the abdominal organs
• Relaxation and self-regulation techniques that calm the vagus nerve and the nerve network in the gut

When should I see a doctor first?

Blood in the stool, unintended weight loss, fever or severe pain should be checked by a doctor first.
