Having excessive gas can be caused by a variety of factors including swallowing too much air, dietary choices, digestive disorders, or intolerances. Common reasons for excess gas include swallowing air by eating quickly, chewing gum, smoking, or drinking carbonated beverages. Foods that often cause gas include beans, lentils, certain vegetables (like broccoli, cauliflower, cabbage), dairy products (especially if lactose intolerant), fructose, sorbitol (found in sugar-free products), and high-fiber foods. Digestive issues such as irritable bowel syndrome (IBS), small intestinal bacterial overgrowth, constipation, and food intolerances like lactose intolerance or fructose intolerance can also contribute to excessive gas. Sometimes, more serious conditions such as celiac disease or intestinal obstruction may cause increased gas. Keeping a food and symptom diary may help identify triggers, and consulting a healthcare provider is advised if gas is accompanied by pain, bleeding, or sudden changes in symptoms.
