A disorienting feeling of unsteadiness (vertigo) can make expectant moms feel as if they’re about to fall or faint (and sometimes they do!).
What causes dizziness during pregnancy?
Early in pregnancy, lightheadedness is likely due to the fact that your body isn’t yet producing enough blood to fill a rapidly expanding circulatory system. (The good news: Your body is gearing up to meet the needs of two bodies instead of one.)
In the second trimester of pregnancy, your growing (and growing!) uterus may put pressure on your blood vessels, which reduces blood flow to your brain, sometimes making your head spin. (By the way, that reduced blood flow is probably the reason you often forget your own name these days.) You might also feel dizzy if your blood sugar drops or you become dehydrated.
Another possible reason you're feeling lightheaded during pregnancy is that you're spending too much time in a hot or stuffy room, especially if you’re wearing clothes that are too tight or warm. Remember, your body is a baby-making oven, generating plenty of its own heat right now.
What you need to know about dizziness during pregnancy:
It's common to feel lightheaded during pregnancy, but if your dizziness persists, or if you actually faint, put in a call to your practitioner just to make sure everything’s okay.
And keep in mind that no matter how "normal" it is to feel dizzy when you’re pregnant, that doesn’t mean you should ignore the feeling. If you’re feeling lightheaded, use common sense: no driving, working out, or handling anything dangerous. If you start to feel especially woozy, sit down immediately so you don’t wind up falling and hurting yourself or your baby.
What to do about dizziness during pregnancy:
You can stop a dizzy spell in its tracks by lying down as soon as you start to feel lightheaded. Elevate your feet to increase blood flow to your brain. Second best: Sit down and bend as far forward as you can, putting your head between your knees, if possible. If there’s no place to lie down or sit, kneel on one knee and bend forward as if you were tying your shoe until the spell passes. And if you need help, don’t be shy about asking.
To keep a spell from starting in the first place:
- Don’t get up too quickly from a sitting or prone position.
- Eat protein at every meal to maintain stable blood-sugar levels.
- Make sure you're eating well during pregnancy — eat several small meals throughout the day.
- Carry healthy pregnancy snacks with you for a quick blood-sugar boost. Good options: a box of raisins, a piece of fruit, or a couple of whole-wheat crackers.
- Make sure you're drinking enough water — at least eight glasses a day; more if it’s hot or you’re working out.
- Dress in easy-to-shed layers in case you start feeling overheated.
- Don’t wear tight-fitting clothes, scarves, or hats.
