During your second trimester, you may feel dizzy or light-headed. Your body is now shunting more blood to your uterus and growing baby -- and less to your head and upper body. Your body also needs more food. You may have dips in blood sugar if you don’t eat enough, which can make you feel light-headed. Finally, your blood vessels are relaxed and widened in response to pregnancy hormones, which lowers your blood pressure. In total, these factors can bring on a dizzy spell.

Call Doctor If:

Step-by-Step Care:

  • Avoid abrupt changes in position. Move slowly when getting up from a chair, bed, or bath or getting out of the shower or car.
  • Avoid standing for long periods. If you have to stand, keep moving your feet and pumping your calves.
  • Stay cool. Getting overheated can cause a dizzy spell. Make sure your shower or bath temperatures are not too hot.
  • Lie on your left side until dizziness subsides.
  • Eat regular meals and snacks to keep your blood sugar stable. Avoid eating foods high in sugar.
  • Stay hydrated.
