White-coat hypertension: When blood pressure rises at the doctor's office


My blood pressure is always higher in the doctor's office than when I measure it at home. Why is this?

No name
No state given


You could have "white coat hypertension." White coat hypertension occurs when the blood pressure readings you have measured at your doctor's office are higher than they are when measured in other settings, such as your home. It's called white coat hypertension because the health care professionals who measure your blood pressure sometimes wear white coats.

It was thought that white coat hypertension was caused by the stress that doctor's appointments can create. Once you'd left the doctor's office, if your blood pressure normalized, there wasn't a problem.

However, some doctors think that white coat hypertension might signal that you're at risk of developing high blood pressure as a long-term condition. The same may also be true for people who have masked hypertension, meaning their blood pressure is normal at the doctor's office, but spikes periodically when measured in other settings. It's thought that even temporary increases in your blood pressure could develop into a long-term problem.

If you have white coat hypertension, talk to your doctor about home monitoring of your condition. This can help determine if your high blood pressure only occurs in the doctor's office, or if it's a persistent condition that needs treatment.
