Frequently Asked Questions
Is it normal to feel dizzy in early pregnancy?
Yes — dizziness is very common in the first trimester as blood pressure adjusts and hormone levels change rapidly.
Can dizziness harm my baby?
Occasional dizziness does not harm the baby. However, if you faint and fall, the impact could be a concern — report any fainting to your provider.
Why do I get dizzy when I lie on my back?
After about 20 weeks, lying on your back can compress the vena cava (a major vein) under your growing uterus, reducing blood flow to your heart and brain.
Can anemia cause dizziness in pregnancy?
Yes — iron-deficiency anemia is common in pregnancy and reduces the oxygen carried to your brain, causing dizziness and fatigue. Your provider will screen for this.
