Low Blood Pressure in Pregnancy: Effects, Signs, Treatment

low blood pressure in pregnancy

During pregnancy, many women experience changes in their blood pressure levels. While high blood pressure is a well-known concern, low blood pressure in pregnancy, or hypotension, can also occur and can have various effects on both the mother and the developing baby. Understanding the signs, effects, and treatment options for low blood pressure in pregnancy is important for ensuring a healthy and comfortable pregnancy journey.

Having low blood pressure during pregnancy won’t cause serious problems. The level of blood pressure has to stabilize to prepregnancy levels after you give birth. However, very low blood pressure is dangerous for both mother and baby.

Effects of Low Blood Pressure in Pregnancy

Low blood pressure during pregnancy can lead to several effects, including:

  1. Dizziness and lightheadedness: A drop in blood pressure can cause feelings of dizziness or lightheadedness, especially when standing up or changing positions quickly. This can make day-to-day activities challenging and increase the risk of falls.
  2. Fatigue and weakness: Low blood pressure in pregnancy can result in feelings of fatigue and weakness, which can affect daily functioning and overall well-being.
  3. Fainting or syncope: In severe cases, low blood pressure during pregnancy may cause fainting or loss of consciousness. This can be dangerous and require immediate medical attention.
  4. Insufficient blood flow to the baby: When blood pressure drops, it can affect the flow of oxygen and nutrients to the baby, potentially leading to growth restriction or other complications.

Others factors

Pregnancy is a period of changes that affect your blood pressure, as carrying a baby causes a drop in blood pressure because of the quick expansion of the circulatory system. Below you can find factors that can also contribute to low blood pressure:

  • Anemia
  • endocrine and kidney disorders
  • nutritional deficiencies
  • infections
  • dehydration

What’s considered low?

Healthcare providers define a normal blood pressure reading as less than 120 mm Hg systolic (the top number) over 80 mm Hg diastolic (the bottom number). When your readings are below 90/60 mm Hg, that’s a sign of low blood pressure during pregnancy. There are a lot of cases when people live with low blood pressure with no signs.

Signs of Low Blood Pressure in Pregnancy

Some common signs and symptoms of low blood pressure during pregnancy include:

  1. Dizziness or lightheadedness
  2. Fainting or feeling faint
  3. Blurred vision
  4. Nausea
  5. Fatigue and weakness
  6. Rapid heartbeat or palpitations
  7. Cold and clammy skin

Dangers of low blood pressure during pregnancy

Having low blood pressure in pregnancy shouldn’t cause concern unless you experience symptoms. Big drops can be a sign of a life-threatening problem. Extremely low blood pressure can lead to falls, organ damage, or shock. Low blood pressure may also be a sign of ectopic pregnancy, which happens when a fertilized egg implants outside of a woman’s uterus.

Treatment for Low Blood Pressure in Pregnancy

If you’re experiencing low blood pressure during pregnancy, it’s important to consult with your healthcare provider for proper evaluation and guidance. The treatment approach may vary depending on the severity of symptoms and individual circumstances. Some common strategies to manage low blood pressure during pregnancy include:

  1. Staying hydrated: Drinking enough fluids, especially water can help maintain blood volume and prevent dehydration, which can contribute to low blood pressure.
  2. Eating small, frequent meals: Consuming smaller, more frequent meals can help stabilize blood sugar levels and prevent drops in blood pressure.
  3. Avoiding sudden changes in position: Slowly transitioning from lying down or sitting to standing can help prevent sudden drops in blood pressure and dizziness.
  4. Wearing compression stockings: Compression stockings can help improve circulation and reduce symptoms of low blood pressure in pregnancy.
  5. Increasing salt intake: In some cases, increasing salt intake under the guidance of a healthcare provider can help raise blood pressure.
  6. Medications: In certain situations, medications may be prescribed to manage low blood pressure, but this will be determined by your healthcare provider.

When you want to connect with your baby by listening to his or her heart, then we advise you to use an at-home fetal doppler. This portable device uses sound waves to check a baby’s heartbeat starting from 10-12 weeks of pregnancy.

Communicate with your healthcare provider

It’s essential to maintain open communication with your healthcare provider throughout your pregnancy. Regular prenatal check-ups will help monitor your blood pressure in pregnancy and ensure the well-being of both you and your baby.

Remember, every pregnancy is unique, and the management of low blood pressure may vary from person to person. Always consult with your healthcare provider for personalized advice and guidance tailored to your specific needs.
