Nausea: Overview

Nausea is that queasy feeling of sickness in the stomach. It is often related to vomiting, but can also occur without vomiting. Nausea is also closely related to appetite loss. Children may refer to nausea as a stomachache. A common cause of nausea is a gastrointestinal disorder such as infectious gastroenteritis, usually with additional symptoms such as vomiting, abdominal pain, and/or diarrhea. Dizziness and balance disorders can also cause nausea (e.g. motion sickness, vertigo). Nausea can sometimes indicate a life-threatening emergency, such as Appendicitis or Diabetic Ketoacidosis (and many others). Various medications also cause nausea as a side-effect. Other causes include febrile illnesses, chemical or electrolyte imbalances, endocrine disorders, heart disorders, and many other possible causes.
