Belching or having mild pain in your upper GI tract may be caused by the swallowing of air, known as aerophagia. On average, individuals swallow two quarts of air a day where half is expelled in the form of some type of gas. If someone swallows a relatively excessive amount of air, there may be some discomfort. This discomfort may be like heartburn that is caused by reflux or GERD, but the consideration of aerophagia may be helpful in managing uncomfortable symptoms. Anxiety or OCD, heavy breathing from exercise, the gulping of water, and even seasonal allergies may all be causing an individual to swallow more air than normal. General lifestyle practices that may help limit aerophagia symptoms include things like the cessation of smoking, eating slowly, and not chewing gum. Therapists can assist with anxiety or OCD associated aerophagia behaviors and physicians can assist with other possible breathing issues.
