Nearly one in five Americans suffer from irritable bowel syndrome, or IBS. The condition is one of the most commonly diagnosed conditions in the United States. Because IBS is closely related to the digestive tract, diet can play a key role in decreasing or increasing symptoms. According to the National Digestive Diseases Information Clearinghouse, symptoms such as constipation, diarrhea and bloating can be controlled by changing your diet. Always discuss dietary changes with your medical doctor.
Time Frame
Dietary changes often take several weeks to take effect. Remember to stay consistent and aim for lasting results, not immediate ones. IBS is a chronic condition, and goals are long-term. Trial and error may be necessary to discover what helps relieve your specific symptoms.
Effects
Diet often improves -- or worsens -- symptoms of IBS. Some people find a high-fiber diet decreases symptoms, yet that same diet can increase symptoms in other patients. Certain foods trigger IBS flare-ups and can increase gas, bloating and constipation.
Foods to Avoid
Specific foods often trigger symptoms of IBS. Gas-producing foods include broccoli, cabbage and Brussel's sprouts. Avoid drinking carbonated, alcoholic or caffeinated drinks. Try to pinpoint whether symptoms increase after consuming dairy products; many IBS patients are lactose intolerant. Cramping and diarrhea can increase when eating foods flavored with artificial sweeteners. Greasy and fried foods also commonly are related to IBS flare-ups.
Misconceptions
Diet and food do not cause IBS, notes the International Foundation for Functional Gastrointestinal Disorders. There is not one diet that will eliminate symptoms associated with irritable bowel syndrome. Each person reacts to certain foods differently and at different times. IBS does not permanently damage the intestine or cause cancer.
Considerations
Consider keeping a food diary for two to three weeks. Write down all foods you eat and any associated symptoms. Include additional factors, such as daily stress levels, sleep patterns and medications, suggests the International Foundation for Functional Gastrointestinal Disorders. Share and discuss your results with your doctor or nutritionist to determine what food choices to increase and what foods to eliminate. Avoid eating quickly and large meals. Small meals and taking time to eat may reduce symptoms. The Mayo Clinic advises IBS patients to drink plenty of water daily to increase hydration, especially if diarrhea is present.
