What causes dizziness during pregnancy ?

 

Rising hormonal levels during pregnancy cause blood vessels to relax and widen. These increase blood flow to your baby but also slow down return of the blood to the veins. As a result , blood pressure is lower than normal and blood flow to the brain is reduced causing dizziness.

 

Low blood sugar levels during pregnancy can also cause dizziness. Your blood sugar level may drop as your body adapts to your changes in metabolism. Women who are anemic or have varicose veins are at increased risk of dizziness.

 

Dizziness during the second trimester may also be due to the increasing  size of your uterus putting pressure on your blood vessels.

 

Lying on your back during the latter parts of pregnancy can also cause dizziness. Lying on your back allows the weight of the baby to press on the large vein ( the vena cava ) that carries blood from your lower body to your heart.
