Nausea

Nausea is a kind of painful sensation in the epigastric region and throat. Nausea may precede vomiting (see). The mechanism of nausea is unclear. It is believed that nausea is the initial manifestation of irritation of the vomiting center. Often, nausea is observed in combination with other autonomic disorders - pallor of the skin, increased sweating and salivation , low blood pressure, cooling of the extremities.

Nausea occurs not only in diseases of the gastrointestinal tract, but also in many others. Nausea occurs with damage to the central nervous system, being one of the symptoms of brain tumors and abscesses, concussions of the brain , as well as neuroses and psychosis.

Nausea can occur during inhalation of carbon monoxide, ingestion of drugs (for example, quinine , digitalis , sulfanilamide and furadone drugs), as well as the formation of toxic substances in the body ( uremia , diabetes , etc.).

Nausea can appear reflexively with irritation of the root of the tongue, pharynx, as well as diseases of the abdominal organs (acute appendicitis, cholecystitis , hepatic and renal colic). Severe forms of vitamin deficiency can lead to nausea. Nausea sometimes appears when traveling in a train, car, or plane (see Carouseling ).

Treatment should be aimed at eliminating the underlying disease. To alleviate the patient's condition, symptomatic treatment should be applied: inhalation of ammonia, peppermint tincture of 10-15 drops to a glass of water inside, mustard plaster on the epigastric region. When nausea appears on an empty stomach, a good result is given by drinking hot tea . With persistent nausea, aminazine at 2 ml of a 2.5% solution intramuscularly is effective, along with 3-5 ml of a 0.5% solution of novocaine or pipolfen, at 0.025 g orally 1-2 times a day (only as prescribed by a doctor).
