What is cyclic vomiting syndrome, what is the cause of frequent vomiting?
Cyclic vomiting syndrome is characterized by episodes of severe vomiting that have no apparent cause.
Episodes can last for hours or days and alternate with symptom-free periods.
Episodes are similar, meaning that they tend to start at the same time of day, last the same length of time, and occur with the same symptoms and intensity.
Cyclic vomiting syndrome occurs in all age groups, though it often begins in children around 3 to 7 years old.
The syndrome is difficult to diagnose because vomiting is a symptom of many disorders.
Treatment often involves lifestyle changes to help prevent the events that can trigger vomiting episodes. Medications, including anti-nausea and migraine therapies, may help lessen symptoms.
