Vomiting or emesis is a natural reflex which occurs when content of the stomach starts returning back to mouth and being ejected into environment. During its initial phase, abdominal muscles start contracting at the same time as diaphragm and respiratory muscles. Second phase is the one during which person expels the content of the stomach. Enormous pressure starts building within the stomach resulting in upwards thrust. Because the pressure is suddenly released, person is able to expel everything down from stomach and back through mouth. This secretion has high level of acidity.

This includes fast breathing, heavy secretion of saliva, pupil dilation, sweating, pale skin and fast heart rate. If the entire process is performed quickly and suddenly, that is, if the person is unconscious because of the alcohol or drugs, content may end in nose or lungs which can cause complications and even death.

Presence of undigested food, especially if this content has alcohol, can help determine cause of vomiting and even disease that is accompanied with it. Same can be said if there is bile inside of it. But, in case there is blood, it is easy to diagnose that there is some severe problem within a body, usually boil or cancer.

Whatever may be the case, it is necessary to consult with a medical professional before using it.
