Quick read
Key points
- 1
Flatulence, or passing wind, is a normal bodily function caused by gas produced during digestion, particularly from the breakdown of certain foods by gut bacteria. Everyone passes gas regularly, and the amount can vary based on diet, particularly with foods like beans, certain vegetables, and fizzy drinks.

What is Farting (Flatulence)?
Flatulence, or passing wind, is a normal bodily function caused by gas produced during digestion, particularly from the breakdown of certain foods by gut bacteria. Everyone passes gas regularly, and the amount can vary based on diet, particularly with foods like beans, certain vegetables, and fizzy drinks.
While normal, excessive or particularly uncomfortable flatulence can sometimes relate to specific foods, food intolerances, or digestive conditions, and adjusting diet or seeking assessment can help if it's bothersome.
02 · Understand
Clinical context
Certain foods are well-known common triggers
Foods like beans, lentils, cabbage, onions, and fizzy drinks are well-known to increase gas production due to how they're broken down by gut bacteria — noticing your own patterns can help identify your specific triggers.
03 · Act
When to See a Doctor
- 1Flatulence is accompanied by persistent bloating, pain, or a change in bowel habit
- 2You suspect a food intolerance and would like guidance on identifying it
- 3Excessive flatulence is significantly affecting your quality of life
- 4You have other digestive symptoms alongside excessive gas
04 · Prevent & manage
Practical steps
Introduce Dietary Changes Gradually
If increasing fibre intake for other health reasons, doing so gradually rather than all at once can help minimise increased gas production as your gut adjusts.
- 1Identify your personal trigger foods.Keeping a food diary can help pinpoint specific foods that increase your gas production.
- 2Eat more slowly and avoid talking while eating.This reduces the amount of air swallowed, which can contribute to gas.
- 3Limit fizzy drinks.These introduce extra gas directly into the digestive system.
- 4Stay physically active.Regular movement can help gas pass through the digestive system more easily.
- 5See a doctor if excessive gas is accompanied by other symptoms.This helps identify whether a specific intolerance or condition needs addressing.

BarnMD Bottom Line
Flatulence is a normal, healthy part of digestion, with certain foods commonly increasing how much gas is produced.
Persistent bloating, pain, or a change in bowel habit alongside excessive gas is worth discussing with a doctor.
