What do you call nausea and vomiting?
Nausea is an unpleasant sensation in the stomach and throat corresponding to a craving for vomiting. We often talk about “heart ache “, of “stomach feeling smeared “, of “high Heart”.

Vomiting is the rejection of stomach contents through the mouth. It corresponds to a mechanical defense reflex of the body intended to empty the stomach. It is possible to vomit food, bile or much more rarely, blood.

  • of cold sweats,
  • of Pallor,
  • Hypersalivation (excess saliva in the mouth),
  • From a feeling of discomfort,

  • Diarrhea.

Vomiting that repeats for more than 7 days is referred to as “Chronicles”.

The mechanism of vomiting
Vomiting takes place in several phases:

  • Closure of the pyloric (orifice that communicates the stomach and duodenum);
  • contraction of the stomach;
  • Contraction of the diaphragm and abdominal muscles;
  • Opening of the Cardia (orifice communicating the esophagus and stomach);
  • Violent evacuation of gastric fluid.

The coordination of vomiting is controlled by a nerve center that is located in the brain.
