In this common condition an excessive amount of saliva is produced by the salivary glands. It may be more common in women, and often there are psychogenic reasons producing this, such as nervous fears, anxieties, tensions and frustrations. It is more likely in patients with hiatus hernia and reflux, an increasingly common disorder.

However, it may also occur in association with many other pathological conditions, such as any disorders in the mouth, tongue or throat, and it may be associated with duodenal ulcers. It is more common during menstruation and early pregnancy.

The saliva forms and is swallowed. A certain amount may enter the cardiac valve and the stomach (often along with air, which in itself often produces dyspepsia and a feeling of abdominal fullness). This gas may finally regurgitate into the lower part of the oesophagus, and together with the collected volume of saliva there, regurgitate into the oral cavity, frequently with an audible burp.

Treatment is aimed at discovering the basic cause and, if any exists, treating and curing that. Otherwise, it is a typical nervous-related problem that often settles down as less thought is given to it, and the mind is directed in other more fruitful paths.
