High Blood Pressure in Pregnancy
Introduction
Pregnancy is an extraordinary journey for women, marked by various health considerations that significantly impact the well-being of both mother and baby. One such concern that warrants close attention is high blood pressure, or hypertension, which can either preexist before pregnancy or develop during gestation. In this comprehensive article, we aim to explore the intricacies of high blood pressure in pregnancy, encompassing its types, prevalence, potential complications, recognition, treatment approaches, and recent developments in diagnostics.
Understanding High Blood Pressure
What is High Blood Pressure?
High blood pressure is characterized by elevated pressure in the blood vessels, a crucial health parameter measured as two figures (e.g., 140/85 mm Hg). The systolic pressure represents the pressure during heart contraction, while the diastolic pressure denotes the pressure when the heart is at rest. Normal blood pressure is generally considered to be below 140/90 mm Hg.
Types of High Blood Pressure in Pregnancy
- Pre-existing High Blood Pressure
- Some women enter pregnancy with a history of hypertension, often necessitating ongoing treatment.
- Medication adjustments may be required, particularly for drugs that pose potential harm to the developing baby, such as Angiotensin-converting enzyme (ACE) inhibitors, Angiotensin-II receptor antagonists (AIIRAs), and diuretics.
- Gestational High Blood Pressure
- This type develops after the 20th week of pregnancy and typically returns to normal within six weeks postpartum.
- Distinguished by the absence of protein in urine, unlike pre-eclampsia.
- Pre-eclampsia and Eclampsia
- A more severe condition involving high blood pressure, affecting multiple organs, and characterized by the presence of protein in urine.
- Pre-eclampsia may progress to eclampsia, a critical phase marked by seizures.

Pre-existing high blood pressure
Some women already have high blood pressure (hypertension) before they become pregnant and they may be on treatment for this. Your medication may need to be changed, so it is important to see a healthcare professional before, or as soon as, you know you are pregnant.
Some women are found to have high blood pressure before they are 20 weeks pregnant. (If high blood pressure is first discovered before you are 20 weeks pregnant, this usually means that you had previously undetected high blood pressure before you were pregnant.)
So, high blood pressure before 20 weeks of pregnancy is not caused by pregnancy but is pre-existing, or chronic, high blood pressure. There are various causes. See the separate leaflet called High Blood Pressure (Hypertension).
If you have pre-existing high blood pressure, you have an increased risk of developing pre-eclampsia during your pregnancy (see below).
Note: if you are taking medicines to treat high blood pressure then, ideally, you should have this reviewed before you become pregnant. Some medicines that are used to treat high blood pressure should not be taken during pregnancy – for example, medicines called:
- Angiotensin-converting enzyme (ACE) inhibitors.
- Angiotensin-II receptor antagonists (AIIRAs) – sometimes called angiotensin receptor blockers (ARBs).
- ‘Water’ tablets (diuretics).
This is because these medicines may harm a developing baby. If you are taking one of these medicines then it is very likely that your medicine will be changed to another medicine that is not known to harm a developing baby.
Gestational high blood pressure
Some women can develop new high blood pressure during their pregnancy. This is called gestational high blood pressure (or hypertension) or pregnancy-induced high blood pressure (or hypertension).
Gestational high blood pressure is high blood pressure that develops for the first time after the 20th week of pregnancy. Doctors can confirm this type of high blood pressure if you do not go on to develop pre-eclampsia during your pregnancy (see below) and if your blood pressure has returned to normal within six weeks of giving birth. If you have gestational high blood pressure, you do not have protein in your urine when it is tested by your midwife or doctor during your pregnancy.
Note: some women may be found to have new high blood pressure after 20 weeks of pregnancy. At first, they may not have any protein in their urine on testing. However, they may later develop protein in their urine and so be diagnosed with pre-eclampsia (see below). You are only said to have gestational hypertension if you do not go on to develop pre-eclampsia during your pregnancy.
Pre-eclampsia and eclampsia
Pre-eclampsia is a condition that can affect some women who develop new high blood pressure after the 20th week of their pregnancy. Pre-eclampsia can also sometimes develop in women who have high blood pressure before they are pregnant (pre-existing high blood pressure) or in women who have protein in their urine before they are pregnant (for example, due to kidney problems).
Pre-eclampsia not only causes high blood pressure; it also affects other parts of your body such as your kidneys, liver, brain and blood clotting system. Pre-eclampsia causes protein to leak from your kidneys into your urine. If you have pre-eclampsia, you will have high blood pressure and protein will be found in your urine when it is tested. Pre-eclampsia gets better within six weeks of you giving birth.
Eclampsia can be a complication of pre-eclampsia. In eclampsia, a woman with pre-eclampsia has one or more fits (seizures or convulsions). This is a serious condition. The aim is to detect and treat pre-eclampsia successfully to try to prevent eclampsia from developing.
How common is high blood pressure during pregnancy?
- Approximately 1 in 10 pregnant women experience issues with high blood pressure.
- Pre-existing hypertension affects up to 3 in 100 pregnant women.
- Gestational high blood pressure occurs in approximately 4 to 8 in 100 pregnancies.
- Pre-eclampsia develops in around 2 to 8 in 100 pregnancies.
Possible Complications
- Mild-to-moderate high blood pressure usually poses low risks.
- Severe high blood pressure and pre-eclampsia elevate risks for both mother and baby.
- Associated risks include an increased likelihood of stroke, organ damage (particularly to the kidneys and liver), blood clotting problems, severe bleeding from the placenta, poor fetal growth, premature birth, and stillbirth.

Mild-to-moderate high blood pressure
If your blood pressure remains mildly to moderately raised and you do not develop pre-eclampsia then the risk is low. Most women with high blood pressure (hypertension) during pregnancy just have mildly or moderately raised blood pressure.
However, it is important that your blood pressure and urine should be checked regularly throughout your pregnancy and that you look out for any signs of possible pre-eclampsia (see below).
Severe high blood pressure or pre-eclampsia
Severe high blood pressure, especially with pre-eclampsia, is serious.
- The risks to you as the mother include:
- An increased chance of having a stroke.
- Damage to your kidneys and liver.
- An increased risk of blood clotting problems.
- An increased risk of severe bleeding from your placenta.
- Having fits (seizures) if you go on to develop eclampsia.
- The risks to your baby include:
- An increased chance of poor growth.
- An increased chance of premature birth.
- An increased chance of stillbirth.
How do I know if I have high blood pressure whilst I am pregnant?
Many women with high blood pressure (hypertension) during their pregnancy do not have any symptoms. This is why your blood pressure is checked regularly by your doctor or midwife during your pregnancy. Your urine is also tested regularly for protein, to look for possible pre-eclampsia.
However, there are some symptoms that you should look out for that could be signs of pre-eclampsia. If you develop any of these, you should see your doctor or midwife urgently so that they can check your blood pressure and test your urine for protein. They include:
- Severe headaches that do not go away.
- Problems with your vision, such as blurred vision, flashing lights or spots in front of your eyes.
- Tummy (abdominal) pain. The pain that occurs with pre-eclampsia tends to be mainly in the upper part of the abdomen, just below your ribs, especially on your right side.
- Vomiting later in your pregnancy (not the morning sickness of early pregnancy).
- Sudden swelling or puffiness of your hands, face or feet.
- Feeling out of breath.
- Not being able to feel your baby move as much.
- Just not feeling right.
Note: swelling or puffiness of your feet, face, or hands (oedema) is common in normal pregnancy. Most women with this symptom do not have pre-eclampsia but it can become worse in pre-eclampsia. Therefore, report any sudden worsening of swelling of the hands, face or feet promptly to your doctor or midwife.

What is the treatment for high blood pressure in pregnancy?
If your doctor or midwife finds that your blood pressure is high during your pregnancy, they will usually check to see if you have any protein in your urine and ask you if you have any symptoms of pre-eclampsia. If your blood pressure remains high, or if you have any signs of pre-eclampsia, you will usually be seen by a specialist (an obstetrician). In order to advise on treatment, there are various questions that need to be considered by the specialist, such as:
- How severe is your high blood pressure (hypertension)?
- Is there pre-eclampsia and, if so, how severe is it?
- How far on is your pregnancy?
- What are the risks to you, the mother, and your baby? This will depend on the severity of your high blood pressure and whether or not pre-eclampsia is present.
Treatment Approaches
- For mild cases, a common recommendation includes a daily dose of aspirin (75-150 mg).
- Severe cases may necessitate urgent specialist attention, potential hospitalization, and medication such as labetalol.
- Magnesium sulfate may be administered to prevent eclampsia.

Recent Developments
Recent advancements in diagnostic tools, specifically placental growth factor (PLGF)-based tests, have been recommended by the National Institute for Health and Care Excellence. These tests assist in assessing suspected preterm pre-eclampsia, aiding in more precise care planning and reducing unnecessary hospitalization.
Conclusion
Effectively managing high blood pressure during pregnancy is pivotal for ensuring the health and safety of both the mother and the developing baby. Regular monitoring, timely intervention, and embracing advancements in diagnostic capabilities contribute significantly to a safer and healthier pregnancy experience.
