Clinical experience with patients suffering from hyperemesis gravidarum (severe nausea and vomiting during pregnancy): thoughts about subtyping of patients, treatment and counseling models.

The medical and psychological treatment of hyperemesis gravidarum (HG) is generally acknowledged as being difficult. It is also recognized that the somatic changes during pregnancy play a role in the process of HG and that psychosocial factors are of particular importance. The following issues have been studied: psychosocial stressors; personality disorders; coping mechanisms and stress tolerance. The reviewed studies mention many different causes of HG. Some produce symptoms in certain women and some will not. As a result of clinical experience and observation during several years treating women with HG from a broad social, cultural and ethnic background in a large inner-city general hospital, we have been able to identify several subgroups of HG patients according to personality pathology, psychiatric symptoms and psychosocial stress factors. Accurate assessment is necessary in order to be able to tailor the interventions to the characteristics and needs of the individual patient. For the various subgroups different treatment strategies are recommended.
