1. Hydrate Well
Occasionally, some women experience low blood pressure during their pregnancy. This can be caused by rapid changes in circulation that normally occur in pregnancy. If this is the case for you, make sure that you hydrate well. There are no guidelines for exactly how much you should be drinking each day, but it may be wise to avoid beverages with caffeine (and alcohol, of course) since this can be dehydrating. Also make sure you hydrate well both during and after exercise and in hot weather.
2. Call Your Doctor for Persistent Vomiting
Many women experience frequent vomiting with pregnancy, especially in their first trimester. Unfortunately, some women develop a condition called hyperemesis gravidarum, which is characterized by persistent vomiting. This can be especially problematic if you are pregnant and have low blood pressure. In these cases, it is very important that you contact your doctor right away. There are several medications available to help you control your symptoms during pregnancy. Also, your doctor may suggest that you receive intravenous fluids until you feel better.
3. Review Your Medication List
Very often, patients who took medications before pregnancy, especially for high blood pressure and thyroid disorders, must have their doses adjusted once they become pregnant. Often, a medication that you tolerated well before you were pregnant may cause symptoms such as dizziness once you become pregnant. It's always a good idea to review your medication list with your doctor before you plan to become pregnant.
4. Stand Up Slowly
Many women who have low blood pressure will feel very dizzy when they stand up quickly after sitting for a long period or when they first get out of bed in the morning. If you are lying down, sit up for a few minutes before you attempt to stand up. If you are sitting, rise up slowly and hold onto a steady object for support.
5. When in Doubt, Get Testing
If your blood pressure is unusually low during your pregnancy, or you have severe symptoms from your low blood pressure, you may want to ask your doctor if you require further testing. Some cardiac and hormonal disorders can present as low blood pressure.
