After a whole amount of studies and suggestive reasons by researchers on why the bowels could become irritated bringing disturbing symptoms, specific causes haven't still been arrived at. However, certain trigger factors have been identified that lead to this condition. They include:

  1. Abnormal motility or movement of the intestines.
  2. Chronic pains in the digestive organs and bowels due to excess gas.
  3. Weak intestinal muscle contractions
  4. Abnormalities in the nervous system; poor coordination of signals from the brain to intestines can cause overreactive changes in the digestive process.
  5. Intestinal infections are caused by changes in gut microbes, which could be fungi, viruses, or bacteria, or after a severe case of gastroenteritis (stomach flu). Also, a small intestinal bacterial overgrowth can lead to IBS.
  6. Hormonal changes like reproductive hormones can kick off IBS or make it worse. 
  7. Stress; exposure to events that increase stress level can aggravate cases of IBS.
  8. Psychological problems like depression, anxiety, posttraumatic stress disorder (PTSD) can trigger IBS.
  9. Food poisoning can lead to gastroenteritis.
  10. The choice of food and diet can contribute to the trigger of IBS. Consumption of foods that can cause flatulence and flares. Such foods include; high-fiber products, dairy products, carbonated and caffeinated products, etc.
