IBS stands for irritable bowel syndrome, a disorder that causes discomfort and pain in the abdomen and alternating bouts of constipation and diarrhea. Constipation is also common in people who do not suffer from IBS. Constipation, as defined by the National Institute of Diabetes and Digestive and Kidney Diseases, is "having a bowel movement fewer than three times per week." Eating certain foods can help both IBS and constipation, but check with your doctor about recommendations for your particular condition.
Fruits and Vegetables
The main recommendations for controlling constipation and symptoms of IBS are to eat a high-fiber diet and drink plenty of liquids, according to UPMC Health System. Fruits that contain high amounts of fiber include fresh, canned or frozen apples, peaches, pears, raspberries and strawberries, and dried apricots, prunes and figs. Vegetables with high-fiber content include broccoli, cauliflower, cabbage, squash, sweet potatoes, carrots and peas. Beans, including pinto, navy, kidney and lima, are also excellent sources of fiber.
Grains and Liquids
Whole-grain breads and cereals, brown rice and rolled oats are all high in fiber and good choices for a diet to help constipation and IBS. In addition to eating a high-fiber diet, persons with IBS or constipation should drink six to eight 8-oz. glasses of water or juice each day.
Foods to Avoid
Some foods contribute to constipation and make symptoms of IBS worse. These include dairy products like ice cream and cheese; foods that are high in sugar and fat, such as fried foods, cakes, pies and cookies; and processed foods, such as hot dogs and bologna. Chocolate, alcohol, carbonated drinks and drinks with caffeine may also aggravate IBS and make symptoms worse.
Other Recommendations
Although a diet rich in fiber is one of the main recommendations for constipation and IBS, it may not help alleviate pain or decrease diarrhea associated with IBS. Introducing a high-fiber diet may cause gas and bloating, which often goes away once your digestive system adjusts. The Mayo Clinic recommends that you consume 20 to 35 g of fiber each day, but to work up to that amount gradually to help prevent gas and bloating.
