Nausea is an unpleasant sensation in the epigastric region, often accompanied by weakness, dizziness, faintness, pallor of the skin, drooling. It usually precedes vomiting, but is often an independent symptom. Nausea occurs both with diseases of the digestive tract and other organs and often has a conditioned reflex character. In this case, increased pressure in the duodenum with a simultaneous decrease in the pressure gradient between her and the stomach.
The following pathogenetic variants of nausea stand out:
- Central nausea (psychogeny, structural lesions of the central nervous system) arises directly from irritation of the vomiting center.
- Reflex nausea (diseases of the digestive system, urinary system, etc.) is noted during vagotonia.
- Hematogenous-toxic nausea is caused by exposure to chemoreceptors of the medulla oblongata metabolites, toxins, drugs and poisons.
