CYCLIC VOMITING SYNDROME IN CHILDREN. BRIEF LITERATURE REVIEW

Cyclic vomiting syndrome (CVS) is a functional disorder of unknown etiology characterized by repeated bouts of vomiting between periods of completely normal health. The average age of children with the onset of cyclic vomiting syndrome, abdominal migraine and classical migraine is 5.3 years, 10.3 years and 11.5 years, respectively, which confirms the hypothesis of progression of autonomic disorder with a change in symptoms. The provoking factors for CVS are stress (34%) and inaccuracies in diet, including the consumption of chocolate and cheese. Positive events such as birthdays, holidays, vacations, and school trips may trigger more CVS episodes than negative experiences. Pharmacotherapy is used to prevent or reduce the frequency of episodes of vomiting. Cyproheptadine is recommended as a first -line treatment for children under five years of age. Amitriptyline is the first choice drug for children over 5 years of age and adolescents.
