When to worry about abdominal pain with irritable bowel syndrome

Irritable bowel syndrome can cause cramping linked with bowel movements, bloating, constipation, diarrhoea, or alternating stool patterns. Symptoms often fluctuate. Pain that wakes you, becomes constant, or is not linked to changes in bowel habits should not be automatically attributed to IBS, particularly if it is a new pattern.

Keep a diary of pain, meals, bowel movements, sleep, stress, and medicines. Maintain fluids and regular meals while avoiding only the foods that clearly trigger symptoms. Arrange a review if your usual pattern changes or self-care is no longer enough. A clinician can check for other causes and discuss a personalised treatment plan.

Seek urgent help for severe sudden pain, a swollen or rigid abdomen, fainting, repeated vomiting, black or bloody stools, or inability to pass stool or gas. Arrange prompt assessment for weight loss without trying, persistent fever, unusual tiredness, symptoms that wake you repeatedly, or a first episode later in adulthood.

Ask whether your symptoms fit IBS, which checks may be useful, how to adjust fibre safely, and what symptom changes should trigger an urgent visit. Discuss food restriction, menstrual links, family history of bowel disease, and medicines that alter stool frequency.
