What is CVS, chronic vomiting syndrome, and how is it treated?

Hi Amoeba,

Thank you for your post! I think you may be referring to Cyclic Vomiting Syndrome (CVS).

"CVS is an unexplained disorder of children and adults that was first described by Dr. S. Gee in 1882. The condition is characterized by recurrent, prolonged attacks of severe nausea, vomiting, prostration with no apparent cause. In some there is severe abdominal pain. Vomiting occurs at frequent intervals for hours or days (1-4 most commonly). The episodes tend to be similar to each other in symptoms and duration and are self-limited with return of normal health between episodes.

Treatment :
Treatment is generally supportive with much importance placed on early intervention. A dark quiet environment is
critical for sleep. Hospitalizations and IV fluid replacement may be necessary. Medication trials sometimes succeed in finding
something to prevent, shorten or abort episodes. It is important to work with a physician who does his/her best to understand
CVS and is supportive.

Long-Term Treatment
The foundation of long-term management involves a responsive collaborative doctor-patient-family relationship,
sensitive to stresses caused by the illness and to triggers such as feelings and attitudes that may pre-dispose to attacks.
Consistent, accessible physician care by a care coordinator who understands and communicates the nature of CVS,
regardless of specialty, is vital to the family's well-being. Connections with the Cyclic Vomiting Syndrome
Association, a family and professional network, does a great deal toward healing a family that has been in doubt and despair
for years."
