Eructations – Excessive belching

Eructations - Excessive belching
Belching is the loud expulsion of gas in the stomach through the mouth .



Like flatulence , when it becomes excessive, belching is a typical manifestation of aerophagia (abnormal swallowing of air). For this reason, it especially affects people who make extensive use of fizzy drinks and chewing gum, drink through a straw, smoke or tend to eat in a hurry and talk a lot during meals. Fewer teeth (hypodontia) and excessive saliva secretion ( drooling ) can also increase the amount of air swallowed.

Within certain limits, belching is a completely physiological phenomenon; just think that normally 70% of intestinal air comes from swallowing, 20% spreads from the blood and only the remaining 10% is produced by the local microflora .

Disorders Associated with Aerophagia

Ingesting too much air during meals – in addition to causing characteristic episodes of violent belching – can cause abdominal cramps and widespread tension. The increase in the gastric bubble during a large meal can even cause a stabbing pain in the chest, similar to that caused by angina pectoris . Most commonly, it is accompanied by nausea , a feeling of heaviness in the stomach , and hiccups .

Other Causes


Belching is often associated with indigestion ; in these cases it is the patient himself who seeks relief by voluntarily ingesting air to encourage belching. In reality, the amount of air introduced is always higher than that emitted, which is why this practice ends up dilating the walls of the stomach even more, triggering a vicious circle between aerophagia and belching. Voluntary aerophagia is also used following the surgical removal of the larynx (usually due to the presence of cancer), in order to be able to speak using gastric air instead of pulmonary air.


Excessive belching can also be connected to the presence of

gastric ulcers , gastritis , hiatal hernia and more generally gastroesophageal reflux . In these cases, however, it is associated with symptoms such as nausea, dyspepsia, retrosternal heartburn (due to the rising acid content in the esophagus) and abdominal pain .


Some drugs used in the treatment of diabetes , such as metformin , can cause belching, especially when taken in high doses; the pressure exerted by the fetus during pregnancy can also cause similar problems.


When the excessive belching is not due to pathological causes, it may be useful to consume one’s meals more calmly, limit the intake of carbonated drinks, abolish – or at least reduce – smoking and avoid too large meals (in particular, the dissociata advises against consuming foods rich in simple sugars in association with sources of starches , fibers or proteins , as these could ferment in the stomach, slow down digestion and cause – among other things – even the unpleasant belching).
