Some causes may not require medical treatment, for example, motion sickness, and other causes may require medical treatment by a doctor, for example, heart attack, lung infections, bronchitis, and pneumonia.
Some causes of nausea and vomiting may be life threatening, for example, heart attack, abdominal obstruction, and cancers.
