Low Blood Pressure During Pregnancy

Pregnant or are you expecting a pregnancy? Worried about how it’s going to be. Don’t worry, being pregnant is one of the most beautiful experiences a woman can have. One might have low blood pressure while pregnant. It is part of normal physiology where the body works to adjust to support the growing life inside it. This article will give you all the required information about the low blood pressure during pregnancy and what all the lookout for.

What Causes the Low BP in Pregnancy?

In pregnancy, the body undergoes a lot of changes including physical as well as hormonal changes. Normal BP of an adult is 120/80 mm Hg of which 120 is the systolic pressure and 80 is the diastolic pressure. During pregnancy, most of the women experience a mid-pregnancy drop of diastolic pressure by 5–10 mm Hg, therefore, causing low bp in pregnancy. This will be automatically corrected by the body during the course of pregnancy.

The most common causes for this drop in bp are:-

  1. Increased circulation to support the womb: The body requires more blood volume to compensate for the increased metabolic activity of the body as well as the baby. This causes a drop in BP.
  2. Increased levels of hormones: The body releases many hormones in pregnancy like progesterone, prostaglandins which support and maintain pregnancy. These hormones also dilate the blood vessels thereby causing low bp in pregnancy.
  3. The growing uterus exerts a pressure against the blood vessels near to it, especially when in lying down position causing the bp to decrease.
  4. Anemia and Decreased blood sugar levels can cause decreased bp levels.
  5. When suddenly getting up from the bed there might be low blood pressure because while lying down the blood accumulates in the veins of the legs and when suddenly one gets up there is less blood in the system as the pooled up blood has not yet entered the circulation effectively thereby causing low BP.
  6. Deficiency in Vitamin B12 or folic acids can cause a low bp in pregnancy.

Are there any Risks Associated with Lowered Blood Pressure While Pregnant?

Generally, there are no risks of low blood pressure during pregnancy. The body will automatically adjust in time but one has to be careful as low bp might cause fainting and frequent episodes may be harmful to the mother and baby. Sometimes if the blood pressure is too low it might cause decreased blood flow to the baby or other organs of the mother and may cause damage. Be sure to visit a doctor if you experience symptoms such as fainting, dizziness, unusual thirst frequently or tell this to your doctor during the monthly checkups.

Low Bp while being pregnant may also be indicative of ectopic pregnancy in which the fetus is growing in some other part of the female reproductive tract other than the uterus. The doctor only will be able to confirm.

What Foods to Eat to Reduce the Risk of Having Low BP During Pregnancy?

  • First and foremost drink lots of Water, Dehydration can cause bp to fall rapidly.
  • Eat food rich in Vitamin B12 such as Meat, Egg yolk, Milk, Yogurt, Cheese.
  • Eat food rich in Folic Acid such as Fruits and Vegetables, Beans, Whole grains, Cereals.
  • Salty food or Salted lemon juice can help to increase bp levels by increasing sodium levels in the body.
  • Avoid High-Carb, oily, fried and processed foods.
  • Avoid Caffeine intake.
