IBS, bloating & low-FODMAP
Understanding irritable bowel syndrome and bloating, and how the low-FODMAP approach works.
What is IBS?
Irritable bowel syndrome is a common, genuine condition where the gut is more sensitive than usual — causing symptoms like bloating, pain and changes in bowel habit. It doesn't damage the bowel, but it can really affect day-to-day life. A diagnosis of IBS is one your doctor makes after considering other causes, so that's the place to start.
The low-FODMAP approach (done properly)
FODMAPs are a group of carbohydrates that can trigger symptoms in some people with IBS. The low-FODMAP approach isn't a forever diet — it's a short, structured, three-step process (reduce → reintroduce → personalise), best done with an Accredited Practising Dietitian so you end up with the widest comfortable diet, not the narrowest. It's about finding your patterns, not labelling foods good or bad.
Food ratings? Use the Monash app
The low-FODMAP diet was developed at Monash University, and their official app has the tested food ratings — it's the gold standard, and we recommend it for looking up specific foods. This hub focuses on the principles and on tracking how you feel, and points you to Monash for the ratings.
A gentle note on food worry
If tracking or cutting out foods starts to feel stressful, or your list of "safe" foods is getting narrow, that's worth talking about with your doctor or dietitian. Eating well should feel supportive, not anxious.
