How is high blood pressure diagnosed?
High blood pressure is diagnosed by a doctor or nurse using a simple and painless test. An inflatable cuff is placed around your upper arm and attached to a pressure gauge (See photograph below). As the cuff deflates, the doctor can measure your blood pressure using a stethoscope.
Blood pressure is usually measured when you are sitting or lying down and relaxed. Ways to prepare yourself before you have your blood pressure measured are provided below.
Most doctors will check your blood pressure several times on different days before deciding that you have high blood pressure.
Some people’s blood pressure can be raised due to the stress of a visit to the doctor or nurse. In this situation you may be asked to wear a device that measures your blood pressure away from the doctor’s office. This is called an ambulatory blood pressure monitor. It will automatically take your blood pressure throughout the day.
Everyone should have their blood pressure measured at least once a year.
Before you have your blood pressure measured:
- Sit quietly and relax
- Don’t drink coffee or tea
- Don’t smoke cigarettes
- Go to the toilet if you need to
