Which medical condition is characterized by a strong urge to vomit?

Nausea is the medical condition defined by a strong urge to vomit. It is often a symptom rather than a standalone diagnosis, commonly associated with various underlying issues such as gastrointestinal disorders, infections, or even motion sickness. The sensation of nausea is a complex interplay involving the central nervous system and gut signaling, leading to the feeling that precedes vomiting.

Anorexia refers to a loss of appetite or an aversion to food, which can lead to significant weight loss but does not specifically involve the urge to vomit. Diarrhea is characterized by frequent, loose, or watery bowel movements and is unrelated to the sensation of nausea. Dyspepsia involves discomfort or pain in the upper abdomen, often accompanied by a sense of fullness or bloating, but it does not inherently include the strong urge to vomit. Thus, nausea distinctly describes the sensation of wanting to vomit, setting it apart from the other choices.
