Because the process of vomiting is really hard on your body, and the cessation of vomiting is very much a relief by comparison. Emesis is a whole-body affair; your entire nervous system and essentially all your muscles are involved, and very little of your body remains under conscious control during the process. You hyperventilate (to keep from aspirating your stomach contents), your heart rate and blood pressure spike, the skeletal muscles in your extremities lock up, your diaphragm plunges deep into your abdomen, and the muscles of your trunk contract hard to increase the pressure on your stomach and … you know. Move things along.
When that stops, along comes the burst of endorphins that accompanies any strenuous physical exertion. The sensation is not unlike a "runner's high." Your blood pressure falls, your heart rate returns to normal, your blood is saturated with oxygen and you experience a short-lived state of mild euphoria due to increased concentrations of special bio-molecules called, unsurprisingly, endogenous euphoriants.
Not to be overlooked, too, is the cessation of nausea. Nausea is a lot more physiological than many people realize. It's not just all in your head. The sensation is primarily caused by changes in your small intestine. Under normal circumstances, your small intestine is undergoing a process called peristalsis. Small, rhythmic muscle contractions — yes, your intestine is muscular; you won't be lifting any weights with it but it's basically a little muscle — move the contents of your intestine steadily "downstream," as it were. When something goes wrong with your digestive system (or something else happens to your body that makes it react like there's something wrong with your digestive system) this regular motility slows or stops, and your whole intestine tenses up. It's this decreased motility and increased tone that serves as the underlying root cause of gastric nausea.
When you vomit, that nausea goes away almost immediately. And that's a tremendous sense of relief. Just the cessation of gastric nausea itself is enough to make you feel much better after you've … you know. Done your business.
Its because is stress. Exams don't cause infections. Your symptoms are due to fear.
It is completely normal to feel nervous before an exam; to have "butterflies in the stomach" or to puke out but if these symptoms are affecting your ability to sit the exam, you should seek help.
Because vomiting triggers some type of relief high/ effect. When throwing up you release dopamine
It gets all of those toxic things out of your system.

Because stress releases damaging hormones into the GI tract, and vomiting gets rid of them. That's why stress causes GI distress in so many people.
Because you're releasing your toxins inside you caused by stress making you feel tired, sick and weak. It reliefs you once it's out.
I don’t know why but I recommend you don’t. Throwing up can cause damage to your voice, throat, and can badly decay your teeth
you need a pregnancy test
possibly cause you're sick
Lol. I hate puking
it is psychological
