Did you know that high blood pressure affects up to 28% of new mamas?
Postpartum hypertension can become an issue in the days after you give birth, even if high blood pressure was never a problem for you during pregnancy.
Lots of cases of postpartum hypertension resolve themselves in the first days of the baby’s life, but there are still some warning signs that everyone should know.
Here, we’ll look at what causes postpartum hypertension, how it’s treated, and the symptoms you should never ignore.

Normal postpartum blood pressure
A normal blood pressure reading for new mamas is the same as for any other healthy adult – below 120/80.
Side note: If you’ve ever wondered what your BP reading means, the first number is the pressure in your artery while your heart muscle contracts (squeezes). The second number is the pressure when your heart muscle is relaxed between beats. It’s all measured in mmHg, or millimeters of mercury, in reference to the traditional instruments where doctors took the readings from a mercury tube.
Is it normal to have high blood pressure after pregnancy?
Yes, as we saw above, it’s quite common to have high blood pressure postpartum.
A high reading is anything over 140/90. At that point, your doctor will start discussing options for getting it down.
Anything over 160/110 is considered an emergency, and that’s much rarer.
By the way, if you’re checking your blood pressure at home and notice that it’s trending high, you should mention it to your doctor straight away.
You’ll usually be checked for hypertension after you give birth and then again at your six-week checkup. But, if you know that your BP is elevated, you shouldn’t wait until your next appointment before getting advice.
Why does postpartum hypertension happen?
So what causes postpartum hypertension? There are several reasons:
No surprise – being in pain raises your blood pressure.
Some pain relievers in the NSAID family (which includes ibuprofen) can also send your pressure up.
In fact, it’s such a common side effect that you probably won’t be offered NSAIDs if you have a history of high blood pressure.
You had a lot of extra blood in your body while you were pregnant.
After you give birth, it hangs around until you essentially sweat the extra water out (postpartum night sweats, anyone?).
But the pressure in your arteries can rise a little while your arteries are still extra-full.
New babies take a while to realize that daytime = playtime and night-time = sleep.
The first few weeks while their circadian rhythm adjusts to the outside world can be tough.
Sleepless nights put your body under stress, which can elevate your blood pressure.
Being a hospital inpatient? Pretty stressful.
Adjusting to life with a newborn? Not always as easy as it seemed in the books.
Even having visitors to meet the new baby can be really draining for new parents.
You’re a superhero, but you’ll probably need some time for all of this to feel normal. The stress of a brand new routine can make hypertension worse.
A note on postpartum hypertension and breastfeeding
Breastfeeding and postpartum hypertension have never been linked.
Although it’s often tough to establish breastfeeding, it’s not enough to explain a case of postpartum hypertension.
If your high blood pressure is down to any of the factors above, you should hopefully be able to manage it at home until it returns to a normal level.
But you should never dismiss high blood pressure postpartum as just ‘one of those things’. That’s because there are some rare but serious conditions where hypertension is a main symptom.
Postpartum preeclampsia can happen between 48 hours and six weeks after you give birth.
It’s possible to develop preeclampsia even if your blood pressure was normal during your pregnancy checkups.
If you have a high blood pressure reading accompanied by any of the following symptoms, treat it as an emergency:
- Changes in your vision
- Pain in your upper abdomen
- Nausea and vomiting
- Difficulty breathing
- Sudden weight gain or swelling, especially around your face, hands, and feet.
Your doctor will check your blood pressure and look for protein in your urine to diagnose postpartum preeclampsia.
The condition is treatable, but it can lead to seizures if there’s a delay in treatment.
HELLP stands for Hemolysis, Elevated Liver Enzymes, and Low Platelets.
Like preeclampsia, it can happen either in the final weeks of pregnancy or after you give birth. It can lead to severe anemia (iron deficiency) and organ damage.
The symptoms overlap a lot with preeclampsia. They also include:
- Shoulder pain
- Pain when breathing deeply.
These conditions are serious, but they are treatable, especially if they’re caught early.
That’s why it’s important that you and your loved ones can recognize the first signs and know when to get help.
How long does postpartum hypertension last?
When it’s ‘regular’ postpartum hypertension, rather than a symptom of a more serious illness, your blood pressure should normalize within a few days.
Even if you need further treatment, hypertension should go away within 12 weeks.
If you have high blood pressure for longer, it’s more likely that you have chronic hypertension, and it simply wasn’t caught before you had all the extra medical attention that comes with pregnancy and a new baby.
How do you deal with postpartum hypertension?
Apart from stopping smoking, some of the best ways to control your blood pressure are:
- Eating a healthy diet
- Exercising when you can
- Unwinding at the end of the day
- Getting a good night’s sleep
But that’s often a big ask when you’ve just had a baby.
If your blood pressure measures in at about 140/90 for 48 hours or more in the postpartum period, your doctor will usually intervene.
ACE inhibitors are drugs that relax your blood vessels and bring your blood pressure down. Beta-blockers, which lower your heart rate, are also an option.
There are questions around ACE inhibitors if you’re breastfeeding, because the small amount that gets into your milk can affect your baby’s blood pressure too.
But this risk decreases as your baby grows. So, if you choose to breastfeed, you should have more treatment options as time goes on.
It’s something to talk about with your doctor to find the solution that works for both you and your little one.
