Fainting
Nausea

Causes of Low Blood Pressure in Pregnancy

Low BP can be caused by several pregnancy-related and lifestyle factors:

Hormonal changes: When you’re pregnant, your body produces hormones like progesterone, which can relax blood vessels. This relaxation can lead to lower blood pressure.
Expanded circulatory system: Your body produces more blood to support the fetus. This expanded system sometimes results in lower blood pressure.
Dehydration: Many pregnant women experience dehydration, which can happen if they don't drink enough fluids. This lack of hydration can lead to drops in blood pressure.
Anemia: When there isn’t enough iron in the body, it can cause anaemia, which may cause low blood pressure.
Resting or Standing Up Quickly: Staying in bed for a long time or quickly getting up after lying down can cause a sudden drop in blood pressure.
Prolonged bed rest or sudden standing: Staying in bed for an extended period or quickly getting up after lying down can cause blood pressure to drop.
Nutrient deficiencies or skipping meals: Not getting enough essential nutrients or skipping meals can also result in low blood pressure.
