Medical Definition of NAUSEA

: a stomach distress with distaste for food and an urge to vomit


noun    (Concise Encyclopedia)

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.
