Symptoms of Cyclic vomiting syndrome: CVS has four phases:

  • Prodrome

  • Episode

  • Recovery

  • Symptom-free interval

The prodrome phase signals that an episode of nausea and vomiting is about to begin. This phase, which is often marked by abdominal pain, can last from just a few minutes to several hours. Sometimes taking medicine early in the prodrome phase can stop an episode in progress. However, sometimes there is no warning: A person may simply wake up in the morning and begin vomiting.

The episode phase consists of nausea and vomiting; inability to eat, drink, or take medicines without vomiting; paleness; drowsiness; and exhaustion.

The recovery phase begins when the nausea and vomiting stop. Healthy color, appetite, and energy return.

The symptom-free interval phase is the period between episodes when no symptoms are present. 1

The main symptoms of CVS are severe vomiting, nausea, and retching (gagging). Episodes usually begin at night or first thing in the morning and may include vomiting or retching up to five or six times an hour during the worst of the episode. Episodes usually last anywhere from 1 to 4 days, though they can last for up to 10 days.

Other symptoms include pallor, exhaustion, and listlessness. Sometimes the nausea and vomiting are so severe that a person appears to be almost unconscious. Sensitivity to light, headache, fever, dizziness, diarrhea, and abdominal pain may also accompany an episode.

In addition, the vomiting may cause drooling and excessive thirst. Drinking water usually leads to more vomiting, though the water can dilute the acid in the vomit, making the episode a little less painful. Continuous vomiting can lead to dehydration, which means that the body has lost excessive water and salts. 1
