As the energy ascends, the contents of the stomach want to go upwards as well, and this leads to the feeling of nausea and vomiting. Typcially, more than one organ is involved, and stress plays an important role in causing it. It is often causes by consuming a pathogen ( virus/bacteria) from our food source. In children, it could be a sign of an infection and should be treated immediately.
