An IBS flare up is a temporary worsening of irritable bowel symptoms — pain, bloating, diarrhoea or constipation. Flares often last days to a couple of weeks and improve with trigger management, but new severe symptoms need review to rule out other causes. GP Carely provides UK online GP consultations for everyday flare advice and red-flag triage.
Common flare symptoms
Cramping related to opening the bowels, bloating, urgent diarrhoea, constipation, mucus without blood, and incomplete emptying are typical. Blood in stools, unintentional weight loss, night waking with diarrhoea, persistent vomiting or new symptoms after age 50 are not “IBS only” features — seek prompt medical advice.
How long do IBS flare ups last?
Many settle over several days once triggers ease; some last one to two weeks. Longer unsettled periods should prompt review of diagnosis, diet, stress, medicines and infection risk rather than assuming “just IBS” forever.
How to calm a flare (safely)
Eat smaller regular meals, hydrate, adjust fibre gradually, note personal triggers, use heat and gentle walking if comfortable, and ask a pharmacist or GP about symptom-matched treatments. Extreme detoxes are not recommended. Stress support matters because the gut–brain axis is real.

Frequently Asked Questions
Is IBS the same as IBD?
No. Inflammatory bowel disease is a different group of conditions. Red-flag symptoms need proper assessment.
Can stress trigger an IBS flare?
Yes. Anxiety and stress commonly intensify symptoms; mental health support can be part of a whole-person plan.
Can an online GP help with IBS?
Yes — for flare advice, medicine questions and deciding whether tests or dietetic referral are needed.
