One of the things that contributes the most to transient inappropriate LES
relaxation is a full stomach. In addition, the full stomach increases the
pressure gradient across the already-inappropriately-relaxed LES making
reflux all the more likely. When patients do reflux gastric contents back
into their esophagus, the typical reaction is to swallow air to clear the
esophagus. It's easy to postulate your partner overeating, swallowing air to
clear the esophagus, belching the swallowed air, but the increased air in
the stomach makes it fuller, which in turn promotes more reflux, which
causes more air swallowing, and on and on it goes ad nauseum (literally).
Nothing to do about it, really. The only way the cycle can be broken is by
decreasing intragastric pressure, which will happen eventually as the
stomach empties itself. The key to keeping it from happening is to avoid
overeating, and avoid substances that decrease the LES tone, such as
alcohol, tobacco, caffiene, certain spices. Weight loss is also an important
component in GERD patients who are obese. That intraabdominal fat also will
contribute to increased intraabdominal pressure, which increases the
gradient across the LES.
