Scientists are not agreed upon the exact way the sensation is processed by the brain, but almost all people have experienced nausea for one reason or another. Note: nausea does not always lead to vomiting. Unfamiliar with the glottis? First, a deep breath is taken, the glottis closes, and the larynx opens the upper esophageal sphincter. Second, the diaphragm contracts to create negative pressure, opening the esophagus. Then, abdominal muscles are contracted and pressure within the gastric system becomes intensified.
It really depends on the situation. Sometimes, vomiting is a necessary bodily function that ultimately protects you in the long run. For example, consuming enough alcohol to achieve a toxic level in your bloodstream will result in vomiting.
When people talk about the stomach flu or a stomach bug, they are actually talking about a virus like the norovirus. With over 19M cases a year, the norovirus is incredibly common and very uncomfortable. Oftentimes, a stomach bug leads to nausea and vomiting.
It can also be caused by eating food contaminated with the virus. Typically, the norovirus causes days of discomfort until the body destroys it. Make sure to stay hydrated, follow the B. Everyone has been there before. Maybe you ate some food left out overnight, or you fearlessly downed questionable sushi.
Either way, food poisoning is another common cause of vomiting. Use soap and warm water for at least 30 seconds. Scrub your fingernails, and in between your fingers as well.
To prevent food poisoning, keep tabs on expiration dates. If you get motion sickness or seasickness, take medication to stop nausea before it starts. If you feel a migraine coming on, take your headache medication at the earliest warning sign. Finally, tell your doctor when pain is intolerable. He or she can help you find ways to minimize it. And if your medication is making you queasy, ask your doctor about alternative options. Discover common triggers for adults, learn what to do after you throw up, and find out which warning signs should send you to the doctor.

Within the brainstem are two anatomically and functionally distinct units that control vomiting:. Bilateral vomition centers in the reticular formation of the medulla integrate signals from a large number of outlying sources and their excitement is ultimately what triggers vomition. Electric stimulation of these centers induces vomiting, while destruction of the vomition centers renders animals very resistant to emetic drugs.
The vomition centers receive afferent signals from at least four major sources:. The chemoreceptor trigger zone is a bilateral set of centers in the brainstem lying under the floor of the fourth ventricle. Electrical stimulation of these centers does not induce vomiting, but application of emetic drugs does - if and only if the vomition centers are intact. The chemoreceptor trigger zones function as emetic chemoreceptors for the vomition centers - chemical abnormalities in the body e.
