Pregnancy-induced hypertension (PIH)—also called gestational hypertension—is high blood pressure that starts after 20 weeks of pregnancy in someone who previously had normal BP.
What it is
BP 140/90 mmHg on two readings (at least 4 hours apart)
No protein in the urine and no signs of organ damage (that’s what separates it from preeclampsia)
Why it matters
PIH can stay mild, but it can progress to preeclampsia, which is more serious for both parent and baby. That’s why close monitoring is key.
Common symptoms
Often none (it’s frequently picked up at routine visits). If symptoms do appear, they may include:
Headache
Swelling of face or hands
Blurred vision
Sudden weight gain
Management
Depends on how high the BP is and how far along the pregnancy is:
Frequent BP checks
Urine tests and blood work
Ultrasounds to monitor baby’s growth
Lifestyle measures (rest, reduced salt if advised)
Medication if BP is persistently high
Delivery is the definitive treatment—timing depends on severity and gestational age
After delivery
BP usually returns to normal within 6–12 weeks
Having PIH increases the risk of high blood pressure later in life, so long-term follow-up matters
If you want, tell me:
how many weeks pregnant you are, and
whether this is for studying, personal experience, or someone you’re caring for
