stomach bubble

Japanese: stomach bubble(英語表記)stomachbubble
stomach bubble

...The phenomenon in which gas (usually air) in the stomach refluxes out of the body through the mouth. When swallowing, a small amount of air enters the stomach, and when not in a recumbent position, it mainly accumulates in the fundus of the stomach (this is called a stomach bubble). Normally, intragastric pressure is about 10 mmHg higher than intraesophageal pressure, but because the lower esophageal sphincter contracts and tightly closes the esophageal outlet, reflux from the stomach to the esophagus does not occur.

*Some terminology that refers to "stomach bubble" is listed below.
