Pregnancy comes with many changes in the body, and sometimes that includes changes in blood pressure. Two common pregnancy-related conditions that involve high blood pressure are gestational hypertension and preeclampsia. While they sound similar, they are actually quite different in how serious they are and how they’re treated.
In this blog post, we’ll explain what each condition means, how they are different, and why it’s important to monitor blood pressure during pregnancy—especially in a surrogacy Gestational hypertension is a condition where a woman develops high blood pressure during pregnancy, usually after 20 weeks. It means the top number in your blood pressure reading (called systolic) is 140 or higher, or the bottom number (diastolic) is 90 or higher—and this happens without any signs of organ damage or protein journey.
What Is Gestational Hypertension?
The word “gestational” just means that it started during pregnancy and was not present before.
Most of the time, gestational hypertension is mild and goes away after the baby is born. But it does need to be watched carefully, because in some cases, it can turn into a more serious condition—like preeclampsia.
What Is Preeclampsia?
Preeclampsia is more serious than gestational hypertension. Like gestational hypertension, it also involves high blood pressure after 20 weeks of pregnancy—but it also includes signs of damage to other organs, most often the kidneys and liver.
One big sign of preeclampsia is protein in the urine, which means the kidneys aren’t working properly. Other symptoms may include:
- Swelling in the hands, face, or legs
- Bad headaches that don’t go away
- Changes in vision, like seeing spots or blurry vision
- Pain in the upper belly (especially on the right side)
- Feeling very nauseous or dizzy
Preeclampsia needs to be taken seriously. If it’s not treated, it can lead to dangerous complications for both the surrogate and the baby, such as preterm birth, low birth weight, or even a condition called eclampsia, which can cause seizures.
What’s the Difference?
Here’s a quick way to understand the difference:
Gestational Hypertension | Preeclampsia | |
When it starts | After 20 weeks of pregnancy | After 20 weeks of pregnancy |
Main symptom | High blood pressure | High blood pressure plus organ problems |
Protein in urine? | No | Yes |
Risk level | Usually mild but must be watched | More serious, needs careful treatment |
Possible to develop into? | Preeclampsia | Can lead to eclampsia or other risks |
Can You Be a Surrogate After These Conditions?
If you’ve had preeclampsia in a past pregnancy, you typically cannot become a surrogate. This is because of the higher risk of it returning in future pregnancies and the potential complications it brings for both the surrogate and the baby. Your safety always comes first.
However, if you’ve had gestational hypertension before, your situation may be reviewed on a case-by-case basis. Some clinics may approve you if the condition was mild, didn’t progress to preeclampsia, and resolved after delivery. Others may have stricter guidelines. Your surrogacy agency and fertility clinic will carefully review your pregnancy and medical history to make the best decision for your health and the success of the journey.
Why This Matters
As a surrogate, your health is just as important as the baby’s. That’s why your medical team will closely monitor your blood pressure at every appointment. Catching signs of gestational hypertension or preeclampsia early helps keep you and the baby safe.
If your doctor sees any warning signs, they’ll take steps right away—like bed rest, medications, or even early delivery if needed. And you’ll have support from Capital Surrogacy and intended parents every step of the way.
