Irritable Bowel Syndrome (IBS) is one of the most common reasons people walk into a gut clinic. It's a functional disorder — meaning the gut looks structurally normal on scans, but it doesn't behave the way it should. The result is a frustrating mix of bloating, cramping, urgency, constipation, or diarrhoea that can come and go for years.
The good news: IBS responds remarkably well to a structured nutrition approach. You don't have to live on plain rice and boiled chicken.
What actually causes IBS symptoms?
IBS is driven by a combination of gut-brain miscommunication, visceral hypersensitivity (a gut that feels things more intensely), altered motility, and shifts in the gut microbiome. Stress, sleep, hormones, and certain foods all amplify symptoms.
- FODMAPs — fermentable carbs in foods like onions, garlic, wheat, beans, apples and milk
- Large or rushed meals that overwhelm gut motility
- Caffeine, alcohol and very fatty meals
- Stress and poor sleep, which sensitise the gut-brain axis
The nutrition strategies that actually help
A short, structured low-FODMAP elimination followed by careful reintroduction is the most evidence-based approach for moderate-to-severe IBS. It's not a forever diet — it's a diagnostic tool that helps you identify your specific triggers.
Alongside that, we look at fibre type (soluble vs insoluble), meal pacing, hydration, and gentle gut-directed practices like diaphragmatic breathing before meals.
IBS care is personal. What soothes one person's gut can flare another's.
