  • Consider using the low FODMAP diet for patients whose irritable bowel syndrome symptoms persist despite following general lifestyle and dietary advice from a healthcare professional with relevant expertise

  • Consider linaclotide (laxative) for people with chronic constipation if other laxatives haven’t worked and they have had constipation for at least 12 months, but ensure adequate follow-up to evaluate its effectiveness

Where the evidence was minimal, recommendations in the original guidance were based on the guideline development group’s experience and opinion of what constitutes good practice. Changes in this update are based on evidence from updated systematic reviews and updated evidence on cost effectiveness. Evidence levels for the recommendations are given in italic in square brackets.

    • -Abdominal pain or discomfort

    • -Bloating

    • -Change in bowel habit.

  • Ask all people presenting with possible symptoms of IBS if they have any of the following “red flag” indicators and refer them to secondary care for further investigation if any are present:
