Dizziness and Fainting: Your Symptoms Manual


What Dizziness and Fainting During Pregnancy Are

Many pregnant women complain of dizziness and lightheadedness throughout their pregnancies, but it usually starts in the second trimester. Fainting (a feeling of dizziness or vertigo that comes on suddenly) is rare, but does happen, even in some healthy pregnant women. Dizziness or fainting will make you unsteady on your feet. This occurs if you stand up too quickly or if you stand for too long. You may be especially prone to fainting in hot weather.


Why Dizziness and Fainting During Pregnancy Happen

There are many reasons for these symptoms. The growth of more blood vessels in early pregnancy, the pressure of the expanding uterus on blood vessels, and the body's increased need for food all can make a pregnant woman feel lightheaded and dizzy. Pooling of the blood in the legs and feet, which happens when you're standing for long periods, can lead to a lack of blood supply to the brain, causing dizziness or fainting. The uterus also demands an increased blood supply, leading to less blood going to the brain.


How to Relieve Dizziness and Fainting During Pregnancy

  • Stand up slowly. No sudden movements.

  • If you're getting out of bath, do it slowly.

  • Avoid standing for too long.

  • Don't skip meals.

  • Lie on your left side.

  • Wear loose clothing.

  • Sit down or lie down if you feel dizzy. 

  • Stay cool in hot weather.

  • If you feel dizzy, bend your head down toward your knees.

  • Lie down with your feet higher than your head.

Call your doctor if you feel faint and have vaginal bleeding or abdominal pain.
