Check your symptoms

The IBS-SS (symptom severity) questionnaire is a simple way of measuring how severe your symptoms are. It's often used by researchers to help them understand whether a treatment like the low FODMAP diet improves symptoms in a meaningful way.

As part of this programme you’ll complete this questionnaire before and after trying a low FODMAP diet. We’ll use your results to help you decide whether the diet has improved your symptoms.

To complete the questionnaire you'll need to answer five questions about your experience of tummy pain, bloating, bowel habits and how IBS has affected your life recently. Please answer the questions based on how you’ve been feeling over the last 7 days.

We recommend you don't complete this more than once every 2 weeks.
