Vomiting (or emesis) is the forceful expulsion of the contents of one's stomach through the mouth. Although it probably evolved as a mechanism for expelling ingested poisons, vomiting may result from many causes not related to poisoning, ranging from gastritis to brain tumors, or elevated intracranial pressure (ICP). The feeling that one is about to vomit is called nausea. It usually, but not necessarily, precedes vomiting, but it does not always lead to vomiting. Antiemetics are somet ...

Vomiting is co-ordinated in the vomiting center in the lateral medullary reticular formation in the medulla. Receptors on the floor of the fourth ventricle of the brain represent a chemoreceptor trigger zone, stimulation of which can lead to vomiting. The chemoreceptor zone lies outside the blood-brain barrier, and can therefore be stimulated by blood-borne drugs that can stimulate vomiting, or inhibit it. There are various sources of input to the vomiting center: As stated earlier, the chemoreceptor trigger zone which li ...

If food lingers too long in the stomach, it can cause problems like bacterial overgrowth from the fermentation of food. Also, the food can harden into solid masses called bezoars that may cause nausea, vomiting, and obstruction in the stomach. Bezoars can be dangerous if they block the passage of food into the small intestine. Gastroparesis can make diabetes worse by adding to the difficulty of controlling blood glucose. When food that has been delayed in the stomach finally enters the small intestine and is absorbed, blood glucose levels rise. Since gastroparesis makes stomach emptying unpredictable, a person ...

Emetophobics are known to go to great lengths to avoid people who may be sick, to avoid being in public places where people may vomit, and above all, to practice eating habits in such a manner as to minimize the chance of their vomiting.

Anxiety about vomiting is a constant presence for most emetophobics, many of whom say they would rather die than vomit. Most emetophobics fear themselve ...

The diagnosis of gastroparesis is confirmed through one or more of the following tests. Barium x-ray . After fasting for 12 hours, you will drink a thick liquid called barium, which coats the inside of the stomach, making it show up on the x ray. Normally, the stomach will be empty of all food after 12 hours of fasting. If the x ray shows food in the stomach, gastroparesis is likely. If the x ray shows an empty stomach but the doctor still suspects that you have delayed emptying, you may need to repeat the test another da ...

Dehydration may require rehydration with oral or intravenous electrolyte solutions. Oral rehydration ...
