High blood pressure does not normally cause any symptoms until it has reached a very high level - typically 180/110 mmHg. Symptoms that your blood pressure has reached a very high level include:
- a headache that lasts for several days,
- nausea,
- dizziness,
- drowsiness,
- blurred, or double vision,
- nosebleeds,
- irregular heartbeat (palpitations), or
- shortness of breath.
If you experience any of these symptoms, you should see your GP as soon as possible.
If you are diagnosed with high blood pressure, it is very important for you to have your blood pressure checked on a regular basis. Adults should have their blood pressure checked at least once every five years although, ideally, it should be checked more frequently, particularly if you have any contributory risk factors.
Most GP surgeries and clinics operate a policy where they will arrange for you to have regular blood pressure checks, and they are also available on request. Children will normally have their blood pressure routinely tested as part of their regular health check-ups.
