Irritable Bowel Syndrome (IBS) is a gastrointestinal disorder that causes several symptoms such as abdominal pain, bloating, and changes in bowel habits (diarrhoea, constipation, or both) that can have a significant impact on your life if not treated or managed correctly.
IBS is typically a lifelong condition which there is currently no cure for; however, dietary modifications, lifestyle changes and medicines can help to ease the symptoms and manage the condition.

A word from one of our gut health specialists
Saskia Knight, BA DipNT Gut Health Nutritionist

"Diagnosing IBS is tricky because there’s no single test, instead, it’s largely symptom based and involves ruling out other conditions. Growing research does point to connections between our gut microbiome and IBS, but a microbiome test itself can’t confirm or diagnose the disorder. What it can do is offer a snapshot of bacterial patterns that help our team personalise evidence based nutrition and lifestyle tweaks to support better overall gut health and potentially ease symptoms."
