Health Tip: When Vomiting Can't Be Explained

(HealthDayNews) -- Some people -- most often children -- experience bouts of severe nausea and vomiting that alternate with longer periods without symptoms.

Doctors call the condition cyclic vomiting syndrome (CVS), according to the National Institute of Diabetes and Digestive and Kidney Diseases. No one knows what causes CVS or how many people have it.

Treatment varies, but people with CVS generally are advised to:

• Get plenty of rest, and take medication to alleviate the nausea and other symptoms.
• Severe nausea and vomiting may require hospitalization and intravenous fluids to prevent dehydration.
• Sedatives may help if the nausea continues.
