SYMPTOMS >> NAUSEA

When you have nausea you feel dizzy, vague discomfort in the abdomen, unwillingness to eat, and a sensation of needing to vomit.

Nausea and vomiting result when the vomiting center in the brain is activated. Certain brain disorders also activate the vomiting. Nausea and vomiting commonly occur with any dysfunction of the digestive tract but are particularly common with gastroenteritis and bowel obstruction.

Vomiting serves to empty the stomach of its contents and often makes a person with nausea feel considerably better, at least temporarily. When blood is vomited, the vomitus is usually bright red (hematemesis). When bile is present, the vomitus is green.

Psychologic problems also can cause nausea and vomiting – person with bulimia vomits to lose weight and a child may vomit to avoid going to school.

You need doctor’s evaluation if vomiting lasts more than 1 day or if you have any other symptoms, particularly abdominal pain, headache, weakness, or confusion.
