Changes to your heart and blood vessels during pregnancy

A

Your body experiences many changes during pregnancy. These changes put extra stress on your body and force your heart to work harder. The following changes are normal during pregnancy. They help your growing fetus receive enough oxygen and nutrients.

  • Increase in blood volume: Your blood volume goes up during the first few weeks of pregnancy and continues rising from there. Most people experience a 40% to 45% total increase in blood volume during pregnancy.
  • Increase in heart rate: It’s normal for your heart rate to increase by 10 to 20 beats per minute during pregnancy. It goes up gradually during your pregnancy and is the highest by your third trimester.
  • Increase in cardiac output: Cardiac output is the amount of blood your heart pumps each minute. By 28 to 34 weeks, your cardiac output may increase by 30% to 50%. This is because of the higher blood volume and faster heart rate. If you’re pregnant with twins, your cardiac output may increase up to 60%.
