Cyclic Vomiting Syndrome and Abdominal Migraines
Cyclic vomiting syndrome (CVS) and abdominal migraines (AM) are two different conditions. Both are rare, and both cause a lot of belly discomfort. They do have some similarities, but they're treated differently.
How They're Similar
Both conditions are linked to migraine headaches -- throbbing pain that can cause nausea and make you more sensitive to light and sound. And both happen most often in children, though kids usually outgrow them by the time they're teenagers.
Between bouts, a person with either CVS or AM feels healthy and has no symptoms.
