Who Is at Risk for Irritable Bowel Syndrome (IBS)?
In this article
It is not clear what causes irritable bowel syndrome, or IBS, but certain factors seem to make some people more vulnerable than others. Risk factors for IBS include:
Sex. About twice as many women as men suffer from IBS, reports the American College of Gastroenterology. Researchers aren't sure why this is so, but they suspect that changing hormones in the female menstrual cycle may have something to do with it.
Age. IBS can affect people of all ages, but it is more likely to occur in people in their teens through their 40s. Studies estimate IBS affects 10% to 15% of the adult population.
Emotional trouble. Some IBS patients appear to be stressed, have a psychiatric disorder, or have experienced some sort of a traumatic event such as sexual abuse or domestic violence. It is not clear what comes first -- the emotional turmoil or the IBS. Nevertheless, there's evidence that stress management and behavioral therapy help relieve symptoms in some IBS sufferers.
Food sensitivities. Some people may have digestive systems that rumble angrily with consumption of dairy, wheat, fructose (a simple sugar found in fruits), or sorbitol (a sugar substitute). Eating certain fare such as fatty foods, carbonated drinks, and alcohol can also invite chronic digestive upset. There's no proof any of these edibles cause IBS, but they may trigger symptoms.
Eating large meals, or eating while doing a stressful activity, such as driving or working in front of the computer. Again, these activities do not cause IBS, but for the hypersensitive colon, they can spell trouble.
