White Coat Hypertension

Some people have high blood pressure only when they visit their health care provider's office. This condition is called white coat hypertension. If your health care provider thinks you may have this condition, you may be asked to wear a device called an ambulatory blood pressure monitor. It is usually worn for 24 hours in order to get an accurate understanding of your blood pressure.

There are over-the-counter blood pressure measuring devices you can purchase in pharmacies and discount chain stores that you can use at home. These include the blood pressure cuff and a stethoscope and electronic monitors, such as digital readout monitors. Always be sure the person who will use the device reads the instructions before taking blood pressure readings. Your health care provider or pharmacist can help you check the device and teach you how to use it. You can also ask for their help in choosing the right type of blood pressure device for you. If you take your blood pressure at home, keep a record of the numbers and take them with you each time you see your health care provider.

Here are some tips for what you can do to ensure as accurate a blood pressure reading as possible:

• Don't drink coffee or smoke for 30 minutes before the blood pressure check.

• Before your blood pressure is checked, sit still for five minutes with your back supported and your feet flat on the ground. Try to rest your arm on a table at the level of your heart.

• Go to the bathroom prior to the reading. A full bladder can change your blood pressure reading.

• Get two readings, taken at least two minutes apart, and average the results.

If you are having your blood pressure taken by a health care provider, ask for the blood pressure numbers. You can also ask to compare the numbers to the ones taken during your last visit.
