What is Vomiting?
Vomiting is the expulsion of stomach contents from your mouth or nose. The term vomit can refer to any liquid that comes out of your body when you are sick. Most commonly, vomitting refers to the action of throwing up blood, pus, or other bodily fluids (such as stool) from the digestive tract. However, vomiting may also refer to the act of spitting out food particles that have been partially digested.
The word vomit is derived from Latin vomer , which means “to spit.” Vomit is often used interchangeably with vomit because both words mean spitting out something. However, there are several differences between these two terms:
1. Vomiting refers to the expulsion of blood, pus, or other bodily fluids from the digestive tract.
2. Spitting out food particles refers to the act of spitting out food particles that have been partially digested.
3. Both actions involve swallowing material into the small intestine and then regurgitating it back up through your throat.
4. The difference between vomiting and spitting out food is the material being regurgitated.
To throw up your stomach’s contents, you must have a functioning gastrointestinal (GI) tract. This includes your esophagus, stomach, small intestine, and large intestine. You also need a working neurological system to coordinate the involuntary muscle movements involved in throwing up. If you suffer from a disease that affects any of these organs, you may not be able to vomit.
The act of throwing up involves several steps. First, your central nervous system (CNS) receives a message that something is going wrong with the contents of your stomach. Then, the CNS sends a signal to your diaphragm and abdominal muscles to contract. This leads to an increase in abdominal pressure, which forces whatever is in your stomach out through your esophagus. Vomiting is often accompanied by a distinctive sound and sensation.
It can be described as a deep cough that is associated with severe pain and a feeling of complete loss of control.
What are causes of vomiting?
Vomiting can be caused by numerous factors. Viral gastroenteritis and food poisoning are the most common causes of vomiting. If you have recently ingested a toxin, there is a chance that you will vomit. Other causes of vomiting include drug side effects, motion sickness, inflammatory bowel disease, and pregnancy.
Vomiting is most commonly triggered by an issue with your stomach or intestines. There are a variety of different issues that can cause vomiting, and they often require different treatment methods.

A community project
The WikiNursery is a project aimed at creating free textbooks for nursing and medical students — and entirely free textbooks. It is a community project which is written and edited by volunteers. Although it has only recently been publically launched, the project was started by Lowit Kwek in October of 2013.
The project was entirely funded by Lowit Kwek.
