What Should You Do About Abnormal Blood Pressure in Pregnancy?

During pregnancy, you undergo plenty of physical changes for your baby to grow and during this period it’s actually better to have normal blood pressure but many women face fluctuating blood pressure. The blood pressure can be defined as the force of the blood that pushes against the artery walls. Everytime time the heart beats, it pumps the blood into your arteries, which carries this blood to all the body organs.

Blood usually moves through your arteries at some certain rate. However, there are different factors that can disrupt this normal rate causing an increase or decrease in your blood pressure. When this pressure increases in your arteries, it can elevate the blood pressure and when this pressure decreases in the arteries, it gives a low blood pressure reading.

The rapid physical changes taking place in your body in these nine months can greatly fluctuate these numbers. Usually, the normal blood pressure reading is 120/80 mmHg and below. If this goes below 90/60 mmHg, it means you have low blood pressure or hypotension and when it goes above 140/90 mmHg it means high blood pressure or hypertension.

Hypertension is more common among pregnant ladies than hypotension. If you get abnormal blood pressure reading then you should think about it seriously. This means both you and your baby are at higher risk of health problems which you can avoid by taking appropriate precautions. Take more prenatal appointments and visit your doctor to monitor your blood pressure. You should also understand the related conditions so that you can manage the situation well.

Hypertension Stage 2: The range starts from 160/100 mmHg and goes beyond it. This means the systolic reading can be 160 or higher while the diastolic reading can be 100 or higher.

What Causes Abnormal Blood Pressure During Pregnancy?

As per AHA 1 among 3 American adults are suffering from hypertension. In pregnancy, this is either chronic or gestational. Chronic hypertension is the one when you have hypertension even before pregnancy. You may have to get diagnosed with this kind of hypertension if you had developed it in the first 20 weeks of your pregnancy. Unfortunately, you still may suffer from this after giving birth. Gestational hypertension is something you get when you develop high blood pressure after 20 weeks of pregnancy. Usually, the reasons behind this include obesity, unhealthy diet and lack of physical activity. Though it gets cured after giving birth to the child, you still have a higher risk of developing hypertension in the future. During pregnancy, your circulatory system expands in order to accommodate your baby. As it expands slowly you may observe a small drop in the blood pressure. As per AHA, this is very common in the first 24 weeks of pregnancy.

Coming to hypotension, it may be caused because of dehydration, low blood sugar, thyroid-related issues, malnutrition, infection, diabetes, heart problems, allergies, blood loss, folic acid and B complex deficiency, etc.

Treating Abnormal Blood Pressure During Pregnancy

Your doctor may recommend fetal monitoring frequently which means you need to keep a track of how often the baby kicks you. Even little movements can cause problem leading to early delivery.

Your doctor may recommend you to take aspirin to control the blood pressure and complications like preeclampsia.

Not so serious or mild hypotension may not require any treatment but you may be advised to be careful while standing up to avoid falling down. However, in serious conditions, you need to do the following.

  • Drink more water and fluids
  • Wear compression socks
  • Stand less on your feet
  • Use medicines like fludrocortisone or midodrine after taking doctor’s advice

A significant drop in your blood pressure can reduce the oxygen supply to the baby. This, in turn, damages your heart and brain affecting fetal development.
