间歇性禁食：患者友好指南

Overview

Gestational hypertension (also called pregnancy-induced hypertension) means your blood pressure rises to 140/90 mm Hg or higher after 20 weeks of pregnancy. Unlike chronic hypertension, it develops for the first time during pregnancy. It does not include protein in the urine or other organ problems that define preeclampsia. Still, it requires careful management because it can progress to preeclampsia or affect the baby’s growth and the timing of delivery.

With regular prenatal care, most people with gestational hypertension have healthy pregnancies and recover fully after the baby is born. Your care team will watch you and your baby closely and create a personalized plan.

Signs & Symptoms

Many people have no noticeable symptoms. High blood pressure is often found during routine prenatal visits. When symptoms occur, they may include:

• Headaches that do not go away with rest or usual pain relief
• Swelling in the hands, face, or feet that is sudden or severe
• Blurred vision, seeing spots, or light sensitivity
• Upper abdominal pain, especially on the right side
• Nausea or vomiting later in pregnancy
• Sudden weight gain from fluid retention

Causes & Risk Factors

The exact cause is not fully understood. It involves changes in blood vessels, the placenta, and how the body handles fluid and blood flow during pregnancy. Risk factors include:

• First pregnancy
• History of gestational hypertension or preeclampsia in a previous pregnancy
• Being age 35 or older or younger than 20
• Carrying twins or more
• Obesity or pre-pregnancy high blood pressure
• Family history of hypertension or preeclampsia
• Certain medical conditions such as diabetes, kidney disease, or autoimmune disorders
• Use of assisted reproductive technology

Diagnosis

Diagnosis is made when blood pressure readings of 140/90 mm Hg or higher are confirmed on at least two occasions at least four hours apart after 20 weeks of pregnancy, without significant protein in the urine or other signs of preeclampsia. Your provider will also check:

• Urine for protein
• Blood tests for liver and kidney function and blood counts
• Fetal growth and well-being with ultrasound and non-stress tests or biophysical profiles as needed
• Your overall symptoms and medical history

Blood pressure is measured with you seated and relaxed, using an appropriately sized cuff. Home monitoring may be recommended between visits.

Treatment & Management

The goals are to keep blood pressure in a safe range, prevent progression to preeclampsia, support fetal growth, and decide the safest time for delivery. Management is individualized and may include:

• Frequent prenatal visits and blood-pressure checks (sometimes weekly or more)
• Home blood-pressure monitoring with a validated device
• Lab work and fetal monitoring on a schedule set by your team
• Medications such as labetalol, nifedipine, or methyldopa if blood pressure reaches levels that need treatment (your provider chooses pregnancy-safe options)
• Activity modification—often reduced activity or modified rest rather than strict bed rest
• Planning delivery, often around 37–39 weeks if blood pressure remains controlled and there are no complications; earlier if preeclampsia develops or the baby shows distress

Aspirin may be recommended in some higher-risk situations earlier in pregnancy for prevention of preeclampsia, but this is decided by your clinician. After delivery, blood pressure usually returns to normal within days to weeks, though monitoring continues postpartum.

Living With It

Living with gestational hypertension means partnering closely with your prenatal care team and making daily choices that support stable blood pressure and overall well-being. Attend every appointment, take medicines exactly as prescribed, and report new symptoms right away. Emotional support matters—talk with your partner, family, or a counselor if you feel anxious. Most people go on to have healthy babies and recover fully after birth. Future pregnancies may carry higher risk, so early prenatal care and discussion of prevention strategies are important next time.
