Experts theorize that aerophagia may be a learned behavior used by those with anxiety to cope with stress. When subjects with excessive belching were unaware they were being studied, their burps were significantly fewer than when they knew they were being observed.
The connection between anxiety and aerophagia was seen in another study published in the American Journal of Gastroenterology. In one study comparing adults with aerophagia to adults with indigestion, researchers found that 19 percent of those with aerophagia had anxiety versus just 6 percent of those with indigestion. Other people who might need assisted breathing and run a higher risk of aerophagia include those with chronic obstructive pulmonary disease (COPD) and people with certain types of heart failure. In one study, researchers found that 50 percent of subjects using a CPAP machine had at least one aerophagia symptom. If the pressure isn’t set correctly, or the wearer has some congestion, too much air can be swallowed. This blockage - which happens because of slack or improperly functioning muscles located at the back of the throat - restricts airflow and interrupts sleep.Ī CPAP machine provides continuous air pressure through a mask or tube. Sleep apnea is a condition in which the airways become blocked while you’re sleeping. One common form of NIV is the continuous positive airway pressure (CPAP) machine used to treat people with obstructive sleep apnea. This is any type of respiratory support that falls short of inserting a tube into a person’s nose or mouth. One example is noninvasive ventilation (NIV). People with certain medical conditions who use machines to help them breathe are more prone to have aerophagia. smoking (again, due to the sucking action).drinking through a straw (sucking draws in more air).eating quickly (for example, taking a second bite before the first one is fully chewed and swallowed).Some things that lead to excessive air swallowing include: How we breathe, eat, and drink play key roles in the formation of aerophagia. Aerophagia can be caused by issues with any of the following: Mechanics Taking in the appropriate amount of air seems simple enough, but for a number of reasons, things can go awry.

The Merck Manual reports that we pass gas through our anus on average about 13 to 21 times a day, although that number is increased in people with aerophagia. Other symptoms include audible air gulping and flatulence. Research published in the journal Case Reports in Gastroenterology found that this distension tends to be less in the morning (probably due to gas being unconsciously expelled during the night through the anus), and progresses throughout the day. One study published by Alimentary Pharmacology and Therapeutics found that 56 percent of subjects with aerophagia complained of belching, 27 percent of bloating, and 19 percent of both abdominal pain and distension. People with aerophagia, who take in a lot of air, experience some uncomfortable symptoms. Most of us do not have a problem processing and expelling this gas. The rest travels through the small intestine and out the rectum in the form of flatulence. We swallow about 2 quarts of air a day just eating and drinking.
