What does vomiting do?

Vomiting is the forceful expulsion of the contents of the stomach through the mouth. It is a natural reflex that helps to protect the body from harmful substances. Vomiting can be caused by a variety of factors, including:

* Food poisoning

* Stomach flu

* Motion sickness

* Pregnancy

* Certain medications

* Stress

* Anxiety

When you vomit, your stomach muscles contract and your esophagus relaxes. This causes the contents of your stomach to be expelled through your mouth. Vomiting can be accompanied by nausea, abdominal pain, and diarrhea.

Vomiting can help to remove harmful substances from the body, but it can also lead to dehydration and electrolyte imbalance. If you are vomiting frequently, it is important to drink plenty of fluids to stay hydrated. You may also need to take an electrolyte supplement to replace the minerals that are lost through vomiting.

If you are vomiting for more than 24 hours, it is important to see a doctor. Severe vomiting can lead to dehydration and electrolyte imbalance, which can be serious.
