High Blood Pressure in Pregnancy
Blood pressure is the force put on the walls of your blood vessels as blood
travels through your body. Blood pressure helps pump blood to your body.
Taking Your Blood Pressure
Blood pressure is often checked by putting a wideband called a cuff around
your upper arm. Air is pumped into the cuff. Your blood pressure is measured
as the air is let out of the cuff.
Blood pressure is one number over a second number.
- The top number is higher and is called the systolic reading. It is the
pressure in the blood vessels when the heart pumps.
- The bottom number is lower and is called the diastolic reading. It is the
pressure in the blood vessels when the heart rests between beats.
Normal Blood Pressure
Normal blood pressure is 120 over 80 or less. Blood pressure varies from
person to person. Each person's blood pressure changes from hour to
hour and day to day.
High Blood Pressure
High blood pressure is also called hypertension. High blood pressure is
140 over 90 or higher. A diagnosis of high blood pressure is not made
until your blood pressure is checked several times and it stays high.
High Blood Pressure and Pregnancy

babies. Women with high blood pressure before pregnancy may have more
problems during pregnancy.

Without treatment, high blood pressure during pregnancy can cause a small
