Irritable bowel syndrome is characterized by lower abdominal pain, constipation, diarrhea, bloating, excessive gas and other feelings of discomfort. IBS is a functional disorder in which the intestine appears normal but it isn't working properly.

IBS doesn't have a clear cause, but abnormal contractions in the intestine, stress and food intolerance all may play a role. If you think you might be suffering from IBS, try the following:

• Keep a food diary to determine what foods trigger your symptoms.

• Eat smaller, more frequent meals.

• Eat high-fiber foods like beans, whole grains, fruits and vegetables.

• Drink plenty of fluids to help prevent constipation.

• Limit your intake of caffeine and alcohol, which can stimulate the intestine.

If you continue to struggle with IBS, talk to your physician and take your food diary with you to help make the diagnosis easier. Contact a dietetics professional for more help with an eating plan that is right for you.
