[Hyperemesis gravidarum: A review].

Vomiting of pregnancy is a physiological symptom of the first trimester and is a frequent reason for consultation as well as hospitalization in the severe forms (hyperemesis gravidarum), which complicate 0.3 to 4% of the pregnancies and represent the first cause of hospitalization in the first trimester. Hyperemesis gravidarum may be responsible for a loss of weight with dehydration and/or hypokalemia. The use of scores such as PUQE-modified or NVPQOL may allow an objective and accurate assessment of symptoms and impairment of quality of life. Organic disease should be always eliminated and hospitalization may be necessary to effectively treat vomiting and correct any electrolyte disorders.
