You may have noticed that your healthcare provider has watched your blood pressure like a hawk throughout your pregnancy. That’s because a spike in blood pressure may point to preeclampsia. The reason behind 8-10% of premature deliveries is hypertensive disorders, including preeclampsia.
So, how do you know if you might be developing preeclampsia?
Preeclampsia is a pregnancy complication marked by high blood pressure, swelling of the extremities, and signs that the kidneys and liver are not working right, such as protein in the urine (this is why you’re asked to pee in a cup during nearly every appointment!). Preeclampsia happens in up to 6% of pregnancies, usually after 20 weeks of gestation. Although it’s potentially a serious condition, most mums with preeclampsia go on to deliver healthy babies.
Like so many things in medicine, we’re not totally sure what causes preeclampsia. What we do know is that it usually occurs during first-time pregnancies, affecting women who:
Your midwife or doctor will check for early signs of preeclampsia, like is a spike in blood pressure above 140/90, and protein in the urine. The tricky part is that you may feel perfectly normal (which is why we must do the tests!). That’s why it’s so important to go to all your prenatal appointments. Those early signs often progress to fluid retention or edema (swelling of the hands, feet, legs, and/or face).
More severe preeclampsia can cause intense headaches, blurry vision, nausea, upper abdominal pain, sudden weight gain, shortness of breath, rapid heartbeat, and infrequent urination (with dark yellow urine). Don’t ignore these symptoms…if you think you have them, get checked right away!
With mild preeclampsia, a provider will monitor you until your little one can be safely delivered. But if the condition worsens, it can impact both of your health.
Preeclampsia reduces blood flow to the placenta. And that may reduce the things your baby needs for good fetal growth (oxygen and nutrients). As for Mum, in rare cases (1-2% of pregnancies) it can be severe.
Preeclampsia cannot be prevented, but healthy habits can help you keep blood pressure low. Throughout pregnancy, drink plenty of water, get regular exercise, avoid alcohol and excessive caffeine, take your prenatal vitamins, eat nutritious foods, and go easy with the saltshaker (too much sodium can boost your blood pressure). If you already suffer from high blood pressure when you become pregnant, ask your healthcare provider about taking a daily low-dose aspirin to help control it.
Another habit that may keep preeclampsia at bay is to take care of your pearly whites! One study showed that having a history of gum disease was linked to preeclampsia…so don’t forget to floss!
Mild preeclampsia can be managed with careful monitoring. If it becomes more severe, healthcare providers often prescribe blood pressure lowering medications and prevent seizures. Corticosteroids may be used to improve the mum’s liver function and platelet count while simultaneously speeding up the baby’s lung development to prepare for an early delivery. The only way to truly cure preeclampsia is to deliver your baby. Your health provider will balance the risks of preeclampsia against the risks of delivering early, often inducing at about 34 weeks if necessary.
While most parents with preeclampsia will welcome healthy babies and fully recover, some will develop complications after birth. Preeclampsia can evolve into severe preeclampsia, eclampsia, or HELLP syndrome (a rare but serious condition that affects the liver and blood). After your baby’s arrival, your healthcare provider will continue to monitor your blood pressure and other preeclampsia symptoms so they can provide you the care you need.

It is important that, in preparation for and during breastfeeding, mothers eat a healthy, balanced diet. Combined breast- and bottle-feeding in the first weeks of life may reduce the supply of a mother's breastmilk and reversing the decision not to breastfeed is difficult. If you do decide to use infant formula, you should follow instructions carefully.
