    Pregnancy, childbirth and the puerperium
Clinical Information
  • A complication of pregnancy, characterized by a complex of symptoms including maternal hypertension and proteinuria with or without pathological edema. Symptoms may range between mild and severe. Pre-eclampsia usually occurs after the 20th week of gestation, but may develop before this time in the presence of trophoblastic disease.
  • A condition of hypertension occurring in pregnancy
  • A pregnancy induced hypertensive state that occurs after 20 weeks of gestation characterized by an increase in blood pressure, along with body swelling and proteinuria.
  • A pregnancy-related disorder characterized by an increase in the blood pressure after the twentieth week of gestation, and by the presence of proteinuria. It may appear up to six weeks post-partum. It may lead to eclampsia with development of tonic-clonic seizures.
  • Pregnancy induced hypertensive states, including eph gestosis when edema and proteinuria accompany hypertension; other hypertensive disorders that develop during pregnancy or the puerperium are preeclampsia and eclampsia, either of which may be superimposed upon chronic hypertensive vascular or renal disease.
  • Toxemia occurring in women in the second half of their pregnancy, characterized by hypertension, and usually by edema and proteinuria, but without the convulsions and coma associated with eclampsia.
