[Evaluation and treatment of hyperemesis gravidarum].

Early pregnancy is characterized by nausea and vomiting which are the most frequent symptoms and the main reason for consulting the physician. This pathological aspect of pregnancy is not yet completely understood. The main doubts concern the etiology, the differential diagnosis and the management and follow-up of the patients. The question as to how and when to treat the symptom is still open. The purpose of this study is to examine, through a literature review, the problems and the appropriate medical approach regarding the severe cases or hyperemesis.
