During pregnancy, you might feel lightheaded or dizzy.
There are a couple of reasons why this can happen. Your blood pressure is lower. Plus, your growing uterus can press on and block the large vein carrying blood to your heart. In either case, this reduces the blood supply in your brain.
Low blood sugar and low iron can also be factors. Sometimes, just getting up too quickly from a sitting position to a standing position can cause dizziness.
To keep from falling during episodes of dizziness, stand up slowly and hold onto the walls and other objects for support and balance. Call your healthcare provider right away if you have repeated dizziness or fainting.
# Eat smaller, more frequent meals.Not eating can make nausea worse. To avoid having an empty stomach, try smaller, more frequent meals instead of three large meals each day. To mitigate nausea in the morning, try placing some plain crackers, dry bread, or cereal next to your bed so you can eat a small amount as soon as you wake up
# Soothe your stomach with ginger.Research suggests that ginger may help settle an upset stomach. Try ginger tea, ginger chews, ginger preserves, or ginger ale made with real ginger. Taking capsules containing 250 mg of ginger four times a day can also help.
# Skip certain foods.Try to steer clear of fatty and greasy foods, very sweet foods, spicy foods, and gas-producing foods. This is not the time to try out that new Indian restaurant! Women have reported that high protein, carbohydrate-heavy, salty, low-fat, bland, and/or dry foods (i.e. nuts, crackers, toast, and cereal) are less likely to cause nausea. You can also combat nausea at meals by keeping foods and beverages separate (avoid drinking beverages while you’re eating).
# Avoid strong smells.One of the best things you can do is avoid environmental triggers, especially strong smells. Keep your distance from cigarette smoke, perfumes, and anything else that seems to affect you. When it comes to cooking, see if someone else can do the food preparation. If you do cook, open the windows to minimize cooking odors.
# Try aromatherapy.On the flipside, smelling mint, lemon, or orange may help alleviate nausea. Try placing a cotton ball or tissue infused with scented oil under your nose. (Many prefer the cotton ball approach to spraying an aroma into the air because you can quickly discard the cotton — and its smell — if it does nauseate you.)
