High blood pressure is a common symptom of preeclampsia. Knowing how to take your blood pressure and when to seek help during pregnancy or postpartum can save your life.
Before taking your blood pressure, go to the bathroom and sit quietly for 3-5 minutes. Within 30 minutes of needing to take your blood pressure, do not smoke, eat, take medicine, have caffeine or exercise.
While taking your blood pressure, be sure to sit up with your left bare arm propped at the same level as your heart. Keep your legs uncrossed and feet flat on the floor.
If your blood pressure is less than 140/90, keep checking and recording your numbers to see what your normal is. (We also say a rise of 10-15 mg above your normal is a cause for concern). If your blood pressure is between 140-159/90-109, call your healthcare provider, report your blood pressure, and ask for their advice. If your blood pressure is 160/110 or higher, seek immediate medical attention.
Blood pressure is important to keep track of in pregnancy because it determines how your pregnancy is managed. It can help inform your provider of potential risks to you and your baby, such as preeclampsia.
