WHAT IS CVS?

CVS has been recognised for over 100 years, but we still know very little about the cause of the problem and there is still no recognised treatment.

CVS is characterised by recurrent, prolonged attacks of severe vomiting, nausea pain and lethargy, with no apparent cause. Vomiting persists at frequent intervals, 5-6 times per hour at the peak, for periods ranging from hours to days or even weeks. 

- Severe and constant, unremitting nausea
- Onset of vomiting is most commonly during the night or early morning
- Repeated vomiting, peaking at up to 5-6 times per hour maybe more
- Retching, often violently
- Pallor, often extreme paleness of the skin
- Headache/ Migraine
- Severe abdominal pain
- Low grade fever
- Vomiting episodes may repeat with regular spacing of days or weeks
- Lethargy or unresponsiveness
- Dizziness
- Perplexing " or unusual behaviours
- Anxiety
