Cyclic vomiting syndrome (CVS) is an issue that occurs mainly in young children but has been known to develop at any age. This condition manifests as repeated vomiting, or cycles of vomiting, with the possibility of periods in between these “cycles” in which you are totally symptom-free. While in the midst of a vomiting cycle, you might experience severe vomiting that might recur as few as six and as many as 20 times before ending. Cyclic vomiting syndrome in St. Louis, MO can develop in as much as 2% of school-aged children and could be challenging to diagnose because vomiting is often a symptom of other GI conditions. The syndrome can often be mistaken for a stomach bug or food poisoning. If your child or you are having symptoms of CVS in, connect with a Specialists in Gastroenterology location near you today.

A vomiting cycle is often similar to prior episodes, meaning they occur at the same time of day, are of a similar level of severity, manifest similar symptoms, and last for a similar duration. The majority of patients report having the below-listed symptoms:

  • Headache
  • Fever that comes and goes
  • Pain in the abdomen
  • Diarrhea
  • Paleness or pallor
  • Unusual urge to sleep or exhaustion

Once the vomiting episode has subsided, the individual might be fatigued and want to sleep. Once rested, the patient might appear to be normal and want to eat and resume usual activities.

It is often difficult to identify the specific cause of a patient's cyclic vomiting syndrome. Vomiting is a typical symptom of various GI conditions, and CVS has many different factors that could be part of the root cause.

Cyclic vomiting syndrome may be initiated by personal behaviors, environmental factors, bodily imbalances, mental state, or internal changes. Distinct CVS episodes may be caused by factors like:

  • Extremely warm/hot weather
  • Menstrual periods
  • Viruses such as colds
  • Allergic responses or problems with the sinuses
  • Eating too much
  • Consumption of specific foods, for example, alcohol, caffeine, chocolate, or cheese
  • Physical exhaustion
  • Motion sickness
  • Panic or anxiety attacks
  • Emotional stress or excitement


Our Specialists in Gastroenterology providers will recommend a treatment plan based on your unique situation. Common treatments for CVS can consist of three primary goals:

  1. Put a stop to the vomiting attack: effort made to halt an attack after it has begun
  2. Rescue therapy: attempt to keep the patient as comfortable as possible if the attack can't be stopped
  3. Preventive medication: an effort to keep any future attacks from starting

If CVS goes untreated, possible complications can include:

  • Dehydration
  • Malnutrition
  • Injury to the esophagus, the main pipe allowing passage of food from the mouth to the stomach
  • Loss of tooth enamel as a result of stomach acid entering the mouth via vomit

In the event your child or you suffer from signs or symptoms of cyclic vomiting syndrome, it's important to seek treatment with our St. Louis, MO gastrointestinal specialists as soon as possible.
