Studies have shown that Low FODMAP diet can improve IBS symptoms by around 75%. In practice my percentage rate has been higher at around 85%. Lesley trained at the King’s College London to practice the Low FODMAP’s diet.

How do FODMAPs affect IBS symptoms?

FODMAP molecules are poorly absorbed in the small intestine of the digestive tract, these molecules then continue their journey along the digestive tract, arriving at the large intestine, where they act as a food source to the bacteria that live there normally.

How the Low FODMAP diet works?
There are 3 stages to the Low FODMAP Diet:

Elimination – we take to the high FODMAPS foods which can last 4-8 weeks depending on symptoms
• Challenge – take each group of FODMAPS and try them, building up the amounts to see if symptoms return
• Food reintroduction – this is when the tolerated FODMAPS are then reintroduced into the diet to see if the layering of the FODMAPS brings back symptoms

Each stage is vital to go through to complete the process accurately. The NICE guidelines for IBS recommend that anyone wanting to try the Low FODMAP diet should be guided by a trained Low FODMAP dietitian.

The low FODMAP diet is a relatively new treatment option. As such the research is always changing so it is vital you are advised accurately by a qualified dietitian.
