Nausea

   Also found in: Dictionary/thesaurus, Medical, Legal, Wikipedia 0.01 sec.
nausea, sensation of discomfort, or queasiness, in the stomach. It may be caused by irritation of the stomach by food or drugs, unpleasant odors, overeating, fright, or psychological stress. It is usually relieved by vomiting. Nausea is frequently present during the early months of pregnancy, and it is a concomitant of motion sickness. However, nausea may also be the symptom of a serious illness; thus persistent nausea should receive medical attention.

nausea

Discomfort in the pit of the stomach associated with disgust for food and a feeling that vomiting will follow, as it often does. Nausea results from irritation of nerve endings in the stomach or duodenum, which stimulate brain centres that control nausea and vomiting. Nausea can be a symptom of minor or serious disorders. Common causes include indigestion (from eating too fast or from stress around mealtime), food poisoning, motion sickness, and pregnancy (morning sickness). Nausea may also arise from any cause of abnormal lack of appetite (e.g., shock, pain, influenza, badly fitting dentures, liver or kidney disease). Simple nausea often is relieved by vomiting.

Nausea 

an unpleasant sensation in the epigastric region, along the esophagus, and in the mouth, associated with stimulation of the vagus nerve; it is often accompanied by dizziness and weakness and usually ends in vomiting. Nausea may be produced by direct stimulation at the root of the tongue (as when a probe is swallowed), by disturbances in the abdominal organs, by various types of intoxications or infectious diseases, by the intake of certain medicines, or by motion sickness. Atropine or sedatives may be used to suppress nausea. Treatment is directed at the underlying disease.

The sickness -- the nausea -- The pitiless pain -- Have ceased, with the fever That maddened my brain -- With the fever called "Living" That burned in my brain.
Vaguely, too, I remember, my father carried me in his arms to the trees on the edge of the field, while all the world reeled and swung about me, and I was aware of deadly nausea mingled with an appalling conviction of sin.
And then something gave, there was a momentary feeling of nausea, a sharp click as of the snapping of a steel wire, and I stood with my back against the wall of the cave facing my unknown foe.
