How common is abdominal pain in irritable bowel syndrome?

With irritable bowel syndrome, pain or cramping may be linked with opening the bowels and may occur alongside constipation, diarrhoea, or alternating bowel habits. Bloating and a sense of incomplete emptying can also occur. The pattern may fluctuate, with some days more troublesome than others. New abdominal pain needs assessment rather than being assumed to be irritable bowel syndrome, particularly when the symptoms differ from your usual pattern.

Keep a simple record of pain, meals, bowel movements, stress, sleep, and any medicines or supplements. This can make patterns clearer at an appointment. Regular meals, enough fluid, and changes to fibre may help some people, but the right approach depends on whether constipation or loose stools are prominent. A clinician or dietitian can help you make changes gradually and avoid an unnecessarily restrictive diet.

Seek urgent medical help for sudden severe pain, blood in the stool, black stools, vomiting blood, fainting, or a rigid swollen abdomen. Arrange prompt review for unexplained weight loss, fever, persistent vomiting, anaemia symptoms such as unusual breathlessness or marked tiredness, or a major change in your bowel habit. These features require assessment for causes other than irritable bowel syndrome.

Ask which features support irritable bowel syndrome and whether your symptoms need blood, stool, or other tests. Discuss a plan for constipation, diarrhoea, cramps, and bloating separately, and ask when you should return if the pattern changes.
