Introduction to nausea and vomiting
Nausea and vomiting are symptoms of an underlying illness and not a specific disease. Nausea is the sensation that the stomach wants to empty itself, while vomiting (emesis) or throwing up, is the act of forcible emptying of the stomach. The term "dry heaves" refers to an episode of vomiting where there is no food in the stomach to vomit, and only clear secretions are vomited.
Vomiting is a violent act in which the stomach almost turns itself inside out - forcing itself into the lower portion of the esophagus (the tube that connects the mouth to the stomach) during a vomiting episode, expelling food and secretions.
What causes nausea or vomiting?
There are numerous causes of nausea and vomiting. These symptoms may be due to the following:
- Acute gastritis (direct irritation of the stomach lining)
- Central causes in which signals from the brain cause nausea and vomiting
- Other illnesses not due to stomach problems
- Medications and medical treatments
- Mechanical obstruction of the bowel
