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.

The Rise of Telehealth in Mental Health Care
Telehealth services, which let you speak to a doctor through a screen, have become a part of our everyday lives. They’ve been especially helpful during the pandemic. Both adult and pediatric mental health care providers say that telehealth appointments have been a lifesaver.
There are pros and cons, and not every patient or situation is a good fit for telehealth. But many providers and patients are happy with it. We spoke to several mental health clinicians to find out how telehealth is working for them and their patients.
What Happens in a Telehealth Appointment?
In Tele Medicine, a telehealth appointment starts with you logging into the app on your device and starting video chat with your healthcare provider.” Your provider will start the session and things go on just like they would at an in-person visit, but on a screen. For kids, mental health care providers get creative to make the session fun and engaging. They might drop off toys or supplies for games to a child’s home ahead of time, and then use them together over a screen.
Benefits of Telehealth for Kids
Kids seem to adapt to telehealth quite easily. In fact, some kids are more comfortable with it than adults! This is mostly because they’ve grown up with technology and are used to using things like FaceTime.
Telehealth can also be a good option for teenagers who want to control what others see of their personal space. However, not all kids are comfortable with telehealth. Some prefer face-to-face sessions.
Benefits:
1. Convenience: Telehealth appointments can happen anywhere, anytime. This means patients can have their appointments during their lunch break, in their car, or anywhere else that’s convenient for them. This has made mental health care more accessible than ever before.
2. Flexibility: Telehealth makes it easier to schedule appointments. This is helpful for families who are living separately and find it hard to all be in the same place at the same time.
Telehealth or In-Person: It’s Your Choice
Nowadays, families have the option to choose between in-person and telehealth visits. Some families prefer telehealth because it’s more convenient. Others prefer in-person visits because they feel a stronger connection when they’re physically in the same room as their provider. There are also certain situations, like a family crisis or suspected abuse, where in-person care might be more appropriate.
The Future of Telehealth in Mental Health Care
Many mental health care providers hope that telehealth will continue to be an option for families. It’s a valuable service that increases access to mental health care.
There are still some challenges that need to be overcome. For example, not all patients have reliable internet access or a device they can use for virtual visits. But with continued support and training in telehealth, these challenges can be overcome.

In recent years, the field of medicine has undergone a revolutionary transformation with the advent of personalized medicine. This innovative approach is fundamentally reshaping how healthcare providers diagnose, treat, and prevent diseases by tailoring medical care to the individual characteristics of each patient. At the heart of personalized medicine lies the understanding that every person’s genetic makeup is unique, and leveraging this genetic information can lead to more effective and targeted treatments.
What is Personalized Medicine?
Personalized medicine, also known as precision medicine, is an approach that uses genetic, environmental, and lifestyle factors to customize healthcare. Unlike the traditional “one-size-fits-all” model, personalized medicine aims to identify the right treatment for the right patient at the right time. This approach can lead to more accurate diagnoses, more effective treatments, and fewer side effects.
The Role of Genetics in Personalized Medicine
The cornerstone of personalized medicine is genetics. The human genome, which consists of approximately 3 billion DNA base pairs, contains the blueprint for every individual’s biological makeup. Advances in genomic sequencing technologies have made it possible to decode this blueprint with unprecedented speed and accuracy.
By analyzing a patient’s genetic information, healthcare providers can identify specific genetic mutations that may be responsible for certain diseases. For example, mutations in the BRCA1 and BRCA2 genes are known to significantly increase the risk of breast and ovarian cancers. Identifying these mutations can help in making informed decisions about preventive measures and treatment options.
Applications of Personalized Medicine
Oncology
One of the most significant impacts of personalized medicine has been in the field of oncology. Cancer is a complex disease characterized by genetic mutations that lead to uncontrolled cell growth. Traditional cancer treatments, such as chemotherapy and radiation, often come with severe side effects because they target both cancerous and healthy cells.
Personalized medicine allows for the development of targeted therapies that specifically attack cancer cells based on their genetic profile. For instance, the drug Herceptin is used to treat breast cancer patients who have a specific genetic mutation in the HER2 gene. This targeted approach not only improves treatment efficacy but also minimizes damage to healthy tissues.
Pharmacogenomics
Pharmacogenomics is another critical area where personalized medicine is making strides. This field studies how an individual’s genetic makeup affects their response to drugs. Variations in genes can influence how a person metabolizes medications, which can impact the drug’s effectiveness and the likelihood of adverse reactions.

By understanding these genetic variations, healthcare providers can prescribe medications that are more likely to be effective and safe for each patient. For example, the anticoagulant drug warfarin has a narrow therapeutic window, and its effectiveness can vary widely among individuals. Genetic testing can help determine the optimal dosage for each patient, reducing the risk of bleeding complications.
Cardiovascular Diseases
Personalized medicine is also making headway in the management of cardiovascular diseases. Genetic factors play a significant role in conditions such as hypertension, heart disease, and stroke. By identifying genetic predispositions, healthcare providers can implement early interventions and personalized treatment plans.
For instance, familial hypercholesterolemia is a genetic disorder that leads to high cholesterol levels and an increased risk of heart disease. Genetic testing can identify individuals with this condition, allowing for early lifestyle modifications and targeted therapies to manage cholesterol levels effectively.
The Future of Personalized Medicine
The potential of personalized medicine is vast, and its future looks promising. As technology continues to advance, the cost of genomic sequencing is expected to decrease, making it more accessible to a broader population. Additionally, the integration of artificial intelligence and machine learning in healthcare can enhance the analysis of genetic data, leading to more accurate predictions and personalized treatment plans.
Ethical and Privacy Considerations
While the benefits of personalized medicine are undeniable, it also raises ethical and privacy concerns. The collection and storage of genetic information must be handled with the utmost care to protect patient privacy. Additionally, there is a need for clear guidelines on how genetic information can be used and shared.
Collaborative Efforts
The successful implementation of personalized medicine requires collaboration across various sectors, including healthcare providers, researchers, pharmaceutical companies, and policymakers. By working together, these stakeholders can create an ecosystem that supports the development and application of personalized treatments.
Conclusion
The rise of personalized medicine marks a significant shift in the healthcare paradigm. By leveraging genetic information, personalized medicine offers the promise of more precise, effective, and individualized treatments. As research continues to uncover the complexities of the human genome, the potential for personalized medicine to improve patient outcomes and transform healthcare is boundless. While challenges remain, the collaborative efforts of the medical community and advancements in technology are paving the way for a future where personalized medicine becomes the standard of care.
