Bloating in Adults

Common Causes

• Excess intestinal gas — Gas from gut bacteria breaking down carbs may build up if foods like beans or dairy are hard to digest, leading to bloating after meals.
• Irritable bowel syndrome (IBS) — IBS might cause ongoing bloating with changes in bowel habits, as research suggests gut sensitivity plays a role.
• Food intolerances — Trouble with lactose, fructose, or gluten could lead to gas and bloating in some adults.
• Constipation — Slow-moving bowels from low fiber or dehydration may trap gas and stool, causing a bloated feeling.
• Stress or hormonal changes — Stress might slow digestion, and hormones during menstrual cycles could increase bloating in women.
