Cyclic Vomiting Syndrome

Parents may not be aware of a particular disorder that is more prevalent in children, cyclic vomiting syndrome (CVS). Cyclic Vomiting Syndrome (CVS) is characterized by recurrent episodes of nausea and vomiting that are not caused by any specific disease and occur between periods of otherwise normal health.

The disorder generally lasts between two and six years and commonly resolves during adolescence. With regard to oral health, CVS affects the mouth and teeth in similar ways to diseases associated with chronic vomiting, such as bulimia, and can cause tooth sensitivity and erosion, cavities, periodontal (gum) disease, dry mouth, salivary gland enlargement and trauma to the oral tissue.

They can inform both the child's pediatrician and dentist. If a healthy child develops chronic episodes of severe nausea and vomiting in conjunction with gastrointestinal, urologic or neurologic symptoms, parents should talk to their pediatrician.
