Many people with irritable bowel syndrome (IBS) find that eating prompts symptoms of abdominal pain, constipation, diarrhea (or, sometimes, alternating periods of constipation and diarrhea), and bloating. Making adjustments to your diet can provide relief. Limit or eliminate foods that may make diarrhea worse, including caffeine, alcohol, milk products, foods high in sugar, fatty foods, gas-producing foods (such as beans, cabbage, and broccoli), and the artificial sweeteners sorbitol and xylitol (often used in sugarless gum and sugarless candy). To reduce constipation, add fiber to your diet, drink plenty of water, and get regular exercise. Keep a daily diary of what you eat and whether you experience symptoms after eating. Eat slowly and have meals in a quiet, relaxing environment.
