Although people with Irritable Bowel Syndrome (IBS) are sensitive to food, few people with this disorder have a food allergy. Between 3-20 percent of people in the U.S. suffer from IBS symptoms, women more than men.
Some people experience minor symptoms, but others’ symptoms are so severe that they disrupt daily life. Also known as spastic colon, irritable colon, mucous colitis and spastic colitis, IBS is not the same as inflammatory bowel disease and is not related to other conditions of the bowel.

IBS is a cluster of symptoms that usually occur together, and which vary in duration and severity from person to person. IBS symptoms include diarrhea, constipation (often alternating), bloating, gas, abdominal pain, cramping and discomfort.
Food intolerances linked to IBS include dairy foods, beans and pulses, indigestible sugars, fried foods, processed foods and cabbage. Sometimes, chamomile, peppermint and ginger can help to reduce symptoms.
