Vomiting
The violent voluntary or involuntary emptying ("throwing up") of stomach contents through the mouth is referred to as vomiting. Vomiting is a natural response for those who have food poisoning.
When your abdominal muscles and diaphragm contract strongly, you are forced to pull up the contents of your stomach and pass them out through your mouth involuntarily. It's a defensive process that happens when your body tries to rid itself of potentially hazardous organisms or toxins. In fact, food poisoning is frequently followed by a bout of, projectile vomiting. Some people's vomiting ceases, while others continue to vomit on a regular basis. To avoid becoming dehydrated, seek advice from a doctor or pharmacist if you're vomiting often and can't keep fluids down.
