Gestational hypertension and mild preeclampsia require similar antepartum management.

Maternal monitoring: goal is to detect progression to severe preeclampsia

• Even without clear evidence of hypertension, maternal symptoms of rapid weight gain, headache, rapid increase in edema, abdominal pain, or nausea and vomiting should raise suspicion of impending preeclampsia and prompt more frequent follow-up.

• Women who meet criteria for either gestational hypertension or mild preeclampsia should be monitored for the development of superimposed or severe preeclampsia.
  • Frequent visits
  • Blood pressure monitoring, at home if feasible
  • 24-hour urine collections to detect a significant increase in urine protein
  • Periodic blood tests of platelet count and liver enzymes
  • Detection of rapid weight gain

Fetal monitoring

• Weekly nonstress tests and ultrasound measurement of amniotic fluid, or biophysical profile

• Fetal ultrasound for growth every 2 to 4 weeks as indicated by current growth trend
