Cyclic vomiting syndrome

Cyclic Vomiting Syndrome

What is cyclic vomiting syndrome (CVS)?

An adult or child who has cyclic vomiting syndrome (CVS) has repeated bouts of severe vomiting and nausea. Between the vomiting episodes, the person's health is normal. The cause of CVS isn't known, but it may be related to migraine headaches.

How is cyclic vomiting syndrome (CVS) treated?

Treatment is centered around easing the nausea and vomiting. The doctor may prescribe medicine.

During very bad bouts of vomiting, your doctor may want you to stay in the hospital for a while. You may get fluids through a vein (I.V.) to prevent dehydration. Dehydration can be serious. Your body needs fluids to make enough blood. Without a good supply of blood, vital organs such as the heart and brain can't work as well as they should.
