Aerophagia: when bloating and belching come from swallowed air, not from food

Bloating, frequent burping, and the sensation of a swollen abdomen are not always related to food digestion. Sometimes, the problem arises because we unknowingly swallow too much air during our daily activities.

This phenomenon is known as aerophagia and occurs when a person repeatedly swallows more air than usual. Habits that contribute to this include eating or drinking too quickly, talking with a full mouth during meals, chewing gum, and consuming carbonated drinks, as well as certain breathing patterns. The excess air that accumulates is either expelled through burping or travels further into the intestine, where it can cause bloating, flatulence, and abdominal pain.

The first step in treatment involves identifying the moments or habits that lead to excessive air swallowing, followed by changing them. If symptoms persist, a doctor may investigate other possible causes of bloating or frequent burping, such as reflux or other digestive conditions. Identifying the precise cause is essential so that the treatment recommended by the doctor targets the underlying problem, rather than merely the symptoms.
