title: Hypertension in pregnancy.
abstract: OBJECTIVE
  Hypertension in pregnancy contributes substantially to perinatal mortality and morbidity of both the mother and her child. High blood pressure is mainly responsible for this adverse outcome, in particular when associated with preeclampsia. Although preeclampsia is nowadays a well-known clinical-obstetrical entity, and screening for this complication has been part of routine care during pregnancy for nearly 100 years, its cause is still enigmatic.
  
  
  RESULTS
  Profound changes of the demographic development of our society, the worldwide rising prevalence of obesity and metabolic disorders, and progress in reproductive medicine will inevitably modify the prevalence of many medical problems in pregnancy. Complications such as gestational diabetes mellitus, chronic hypertension, and preeclampsia will rise and an interdisciplinary approach is necessary to handle these women during pregnancy and also after delivery. Indeed, it is now well established that these women and their offspring born large or small-for-gestational age are at increased risk for severe cardiovascular and metabolic complications later in life.
  
  
  CONCLUSIONS
  Knowledge of the pregnancy course is not only important for an obstetrician but also increasingly inevitable for the general practitioner. Recognition, classification, and adequate management of hypertensive pregnancy disorders and associated complications may considerably reduce perinatal death and morbidity.
