Pregnancy is a time of joy and anticipation, but for some women, it comes with hidden challenges that can pose serious risks. One significant concern is the fluctuation in blood pressure levels, which can disrupt the essential balance required for a smooth and healthy pregnancy.

Conditions such as gestational hypertension, preeclampsia, or chronic hypertension can threaten both the mother’s and baby’s well-being, potentially leading to complications such as preterm birth, low birth weight, or even life-threatening outcomes.

In this blog, we will explore abnormal blood pressure levels during pregnancy and how to manage them appropriately.

Understanding Normal Blood Pressure Levels in Pregnancy

Generally, normal blood pressure is considered to be around 120/80 mm Hg. However, during pregnancy, these values may slightly vary. Blood pressure readings are categorised as follows:

Normal: Less than 120/80 mm Hg
Elevated: 120-129/<80 mm Hg

Hypertension:

Stage 1: 130-139/80-89 mm Hg
Stage 2: 140 or higher/90 or higher mm Hg

Causes of Abnormal Blood Pressure in Pregnancy

Some common causes of abnormal blood pressure during pregnancy include:

Gestational hypertension: High blood pressure that develops after 20 weeks of pregnancy, usually resolving after delivery.
Preeclampsia: A serious condition characterised by high blood pressure and damage to organ systems, often the liver and kidneys. It typically develops after 20 weeks of pregnancy and can be life-threatening if untreated.
Chronic hypertension: High blood pressure that exists before pregnancy or before 20 weeks of gestation.
Chronic hypertension with Superimposed Preeclampsia: This occurs in women with pre-existing hypertension who develop worsening blood pressure and other signs of preeclampsia during pregnancy.
Pregnancy-induced hypertension: Sometimes used interchangeably with gestational hypertension, this refers to high blood pressure during pregnancy without signs of pre-eclampsia.
Multiple gestation: Carrying twins or more can increase the risk of high blood pressure during pregnancy.

It is vital for pregnant women to attend all prenatal appointments and regularly monitor their blood pressure to detect any abnormalities early. If you have concerns, consult your healthcare provider for proper evaluation and management.

Abnormal Blood Pressure Levels

Symptoms of Abnormal Blood Pressure Levels

Common symptoms include:

Severe headaches
Vision problems
Swelling in the hands and face
Shortness of breath
Nausea or vomiting
Upper abdominal pain

Risks Associated with Abnormal Blood Pressure

Uncontrolled high blood pressure during pregnancy can lead to complications such as:

Reduced blood flow to the placenta
Preterm birth
Low birth weight
Placental abruption
Development of HELLP syndrome (Haemolysis, Elevated Liver enzymes, Low Platelet count)

Management and Treatment

Proper management of abnormal blood pressure levels during pregnancy is crucial to minimise risks for both mother and baby. Strategies include:

Regular prenatal check-ups to monitor blood pressure.
Dietary modifications, such as reducing sodium intake.
Increased physical activity, as recommended by healthcare providers.
Medications prescribed by a healthcare provider, if necessary.
Rest and stress management techniques.

In some cases, early delivery may be necessary to safeguard the health of the mother and baby.

Did You Know?

Heart problems during pregnancy can sometimes mimic common pregnancy symptoms like fatigue or shortness of breath, making regular check-ups crucial for early detection and care.
High blood pressure during pregnancy, known as preeclampsia, affects about 5-8% of pregnancies and can cause serious complications if left untreated.
Abnormal blood pressure levels, whether too high or too low, can restrict blood flow to the placenta, potentially affecting the baby’s development.

Myths & Facts

Myth 1: Abnormal blood pressure levels are solely caused by stress.
Fact: While stress can contribute, factors like genetics, obesity, pre-existing conditions, or pregnancy-specific conditions (e.g., preeclampsia) play a larger role.

Myth 2: Only high blood pressure is dangerous during pregnancy.
Fact: Low blood pressure (hypotension) can also pose risks, such as dizziness, fainting, and reduced blood flow to the baby.

Myth 3: High blood pressure during pregnancy guarantees complications for the baby.
Fact: With proper care and monitoring, many women with high blood pressure deliver healthy babies. Early diagnosis and treatment are key.

Conclusion

In summary, lifestyle modifications, including a balanced diet, hydration, stress management, and adequate rest, are vital for maintaining healthy blood pressure levels. For more severe cases, medical interventions and close monitoring become indispensable. Addressing abnormal blood pressure levels promptly safeguards maternal health and ensures a healthier, safer pregnancy journey.

When to Seek Help

If you experience persistent headaches, vision changes, severe swelling, or sudden weight gain during pregnancy, it could indicate abnormal blood pressure levels. Consult a healthcare provider immediately to ensure your safety and your baby’s well-being.
