What Causes Bowel Symptoms in Irritable Bowel Syndrome



While there are many risk factors triggering the onset of symptoms, the exact reason is still unknown. It is found that even certain food can trigger IBS symptoms. A few triggers are:

  1. Abnormal movements of the colon and small intestines (too fast or slow, or too strong)
  2. Hypersensitivity to pain from a full bowel or gas
  3. Food sensitivities, possibly caused by poor absorption of sugars or acids in food
  4. Gastroenteritis (“stomachflu” or “stomach bug”), a viral or bacterial infection of the stomach and intestines, may trigger IBS symptoms
  5. Psychological conditions such as anxiety or depression are observed in many people with IBS, though these conditions have not been found to be a direct cause of IBS.
  6. Reproductive hormones or neurotransmitters may be off-balance in people with IBS.
  7. Small intestinal bacterial overgrowth (SIBO)
  8. Genetics is thought to be a possible cause of IBS, but so far this hereditary link has not been proven.
