Aerophagia: the causes

The main causes of aerophagia are either related to chewing and swallowing, or related to the type of food consumed.

  • Quick chewing and swallowing promotes air absorption during the meal.
  • Stress or anxiety can also increase aerophagia.
  • Hyper salivation and its causes promote flatulence.


Some foods are also involved in the occurrence of aerophagia:

  • Chewing gum chewing is responsible for the digestive absorption of air.
  • Aerophagia is aggravated by the consumption of soft drinks, such as soda or sparkling water.
Some foods are responsible for bowel distention without being specifically responsible for flatulence. They can therefore aggravate the symptoms.

It is therefore to avoid foods that are:

  • Source of fructans: wheat, rye, barley, onions, garlic, Jerusalem artichokes, artichokes, asparagus, beetroot, chicory, leeks, broccoli, Brussels sprouts, fennel.
  • Sources of galactans : pulses and beans
  • Sources of fructose, lactose or polyols .
° Fructans: soluble fibers that are neither digested nor assimilated.
° Galactans: a carbohydrate intermediate between sugar and starch, naturally present in legumes and used in the food industry as an additive to thicken or stabilize food.
° Polyols (or: sugar-alcohols) : chemical compounds, naturally present in small quantities in many fruits and vegetables, often used for the manufacture of sweeteners in the food industry.
