What is Gestational Hypertension?

Gestational hypertension (GH) is defined as a blood pressure of ≥140/90 mmHg after 20 weeks' gestation in the absence of proteinuria or other features of end-organ damage. It affects approximately 5–10% of pregnant women.

GH progresses to pre-eclampsia in 15–50% of cases, particularly when diagnosed before 34 weeks. Regular proteinuria screening, blood pressure monitoring and laboratory assessment are therefore essential.

If hypertension persists beyond 12 weeks after delivery, the diagnosis is revised to chronic hypertension. A history of GH increases the long-term risk of cardiovascular disease.

Symptoms

Office or home readings of ≥140/90 mmHg
Headache
Oedema (face, hands, feet)
Most patients are asymptomatic
Visual changes if pre-eclampsia develops
Foamy urine if proteinuria appears

Risk Factors

First pregnancy
Previous gestational hypertension or pre-eclampsia
Multiple pregnancy
Obesity
Family history of hypertension
Chronic kidney disease

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • If a home reading is ≥140/90 mmHg
  • If headache, visual disturbance or swelling begins
  • For routine blood pressure measurement at antenatal visits
  • Urgently if signs of progression to pre-eclampsia appear

Treatment Methods

01
Mild GH (<160/110): close ambulatory monitoring (twice weekly)
02
Severe hypertension (≥160/110): start antihypertensive therapy (labetalol, nifedipine)
03
Continue regular blood pressure and proteinuria monitoring
04
Serial fetal growth and biophysical profile ultrasound
05
Delivery: recommended at ≥37 weeks; earlier in severe cases
06
Postpartum blood pressure follow-up and counselling on long-term cardiovascular risk
