NICE quality standards describe high-priority areas for quality improvement in a defined care or service area. Each standard consists of a prioritised set of specific, concise and measurable statements. They draw on existing guidance, which provides an underpinning, comprehensive set of recommendations, and are designed to support the measurement of improvement.

This quality standard covers the diagnosis and management of irritable bowel syndrome in adults. It does not cover other gastrointestinal disorders such as non-ulcer dyspepsia, coeliac disease and inflammatory bowel disease. For more information see the irritable bowel syndrome topic overview.
