Cyclic Vomiting Syndrome (CVS)

It can be difficult to determine a singular cause of an individual’s cyclic vomiting syndrome. Vomiting is a fairly common symptom of various GI diseases, and CVS, in particular, has many different factors that could contribute to its cause.

CVS may be caused by personal behaviors, external influences, bodily imbalances, mental state, or internal changes. Specific CVS episodes may be caused by things such as:

• Hot weather
• Menstruation
• Sicknesses - such as colds
• Allergies or sinus problems
• Overeating
• Eating certain foods -alcohol, caffeine, chocolate, or cheese
• Physical exhaustion
• Motion sickness
• Anxiety or panic attacks
• Emotional stress or excitement

If you feel your episodes are triggered by any of the above or you require help identifying your triggers, contact your local GI Alliance.

Common treatments for cyclic vomiting syndrome may consist of three main goals:

1. End the vomiting episode: attempt to stop an attack after it starts
2. Rescue therapy: attempt to keep the patient as comfortable as possible if the attack cannot be stopped
3. Prophylactic medicine: attempt to prevent future attacks

Treatment will vary between different individuals and different cases of cyclic vomiting syndrome. You should speak with your doctor/your child’s doctor about the best treatment options for you/your child.

What are the complications of CVS?

If cyclic vomiting syndrome (CVS) is left untreated, possible complications may include:

• Dehydration
• Malnutrition
• Injury to the esophagus, the main food pipe connecting the mouth to the stomach
• Loss of dental enamel from stomach acid that enters the mouth in the vomit

If you or your child are experiencing symptoms, it's important to seek treatment through GI Alliance as soon as possible.
