Is dizziness / lightheadedness normal during pregnancy?
First, a quick check
If any of this matches what you're experiencing, call your midwife or doctor before waiting it out. Checking is routine, and that's what they're there for.
Fainting, dizziness with chest pain/palpitations, vaginal bleeding, or severe headache/vision changes.
If none of these apply, here's what's usually going on.
Most common in the any trimester. See what else is expected at your stage.
What's usually normal
Brief lightheadedness on standing quickly or when hungry.
Why it happens
Blood-vessel dilation, blood pooling, lower blood sugar, or lying on the back late in pregnancy.
What can help
Rise slowly, eat regularly, hydrate, avoid lying flat on your back in later pregnancy (lie on your side).
