Gas and Flatulence

Overview

Passing gas (flatulence) and belching are normal bodily functions. Everyone produces gas, and most people pass gas many times a day. Excess gas becomes a concern when it is frequent, socially troublesome, or accompanied by bloating, pain or a change in bowel habit. Most excess gas comes from swallowed air and the breakdown of certain foods by gut bacteria, and it improves with simple dietary changes.

Common causes

• Swallowed air from eating or drinking quickly, chewing gum, or carbonated drinks.
• Foods that produce gas — beans, lentils, certain vegetables, onions, and, for some, dairy.
• Food intolerances such as lactose intolerance.
• Constipation, which allows more gas to build up.
• Irritable bowel syndrome (IBS).
• Acid reflux and indigestion, which increase belching.

Management and diet

Management focuses on eating slowly, avoiding carbonated drinks and chewing gum, identifying and limiting personal gas-producing foods, and treating any underlying constipation or IBS. A short trial of reducing common trigger foods, then reintroducing them one at a time, helps identify which foods affect you personally.

When it needs review

• Excess gas with persistent bloating, pain or a change in bowel habit.
• Gas with weight loss, blood in the stool or persistent diarrhoea.
• Gas that is new, persistent and not helped by dietary change.
