There are active belching and passive belching. Passive belching mostly occurs shortly after a meal or drink, and excessive gas in the stomach is squeezed by gastric peristalsis and belched out. Because the source of gas in the stomach, passive belching is also known as gastric belching, commonly known as “hitting the diaphragm”. Everyone experiences diaphragmatic belching, which is passive and not under conscious control. Active belching occurs during non-meal times when the discomfort is relieved by a swallowing motion with the mouth slightly open to swallow a small amount of air, which is then belched out. Because the swallowed gas is still in the esophagus and will be belched out in the future when it enters the stomach, active belching is also known as esophageal belching, which is active and under conscious control, as the saying goes, “if it sticks in your throat, you can’t spit it out. Active belching is also a common experience for everyone. Occasional belching is not considered excessive. Frequent belching is a disease called excessive belching, and frequent belching must be active and is a psychological disease, mostly triggered by mental stress or adverse stimuli. Patients often report chest tightness or significant choking in the throat, and even suspect esophageal tumors, but there is no obstruction to eating and swallowing, and no abnormal findings on pharyngeal examination or gastroscopy. Belching disappears naturally when concentrating, and then returns when remembering or talking to someone about discomfort, and suffocates when not belching. Because of the impact of airflow, the throat becomes a little sore and uncomfortable after several belches, which in turn increases the patient’s suspicion. When describing the condition to the doctor, the patient often belches continuously, and then immediately discontinues when the doctor points out that this is an active behavior. Since it is a psychological disease, the treatment is to use “heart medicine”. After listening to the explanation, let go of the knot, and insist on not actively belching, most people will be well in a day or two. Slightly worse improvement can increase the time for recreation, exercise, and unconsciously forget about it. Only a very small number of people with serious psychological disorders need to take psychological adjustment drugs under the guidance of a doctor.
