Presentation Nausea and vomiting present few problems to the pharmacist. Recurrent cases and those which cannot be readily attributed to motion sickness, pregnancy or a temporary dietary problem should be referred. Symptom complex Nausea is an unpleasant sensation which is experienced in the throat and epigastrium. It may be associated with skin coldness and cold sweats. Retching is the intense rhythmic hyperventilation and abdominal spasms that usually precede vomiting.
Vomiting is the act of ejecting stomach and sometimes intestinal content through the mouth.
If bile is present, the vomit is extremely bitter. If the problem has a minor gastric cause, stomach pains and diarrhoea may be present. Alcohol-induced nausea and vomiting may be associated with a headache as well as gastric symptoms. The areas involved are the stomach, oesophagus, diaphragm and mouth. Universal factors Nausea and vomiting are symptoms, not diseases.
