If you experience symptoms such as light-headedness, dizziness and fainting, you should talk to your health professional. A relatively low blood pressure may be of no concern in fit, healthy people. Low blood pressure (also called hypotension) is usually only a problem if it causes symptoms or results in adverse effects. Your health professional will most likely measure your blood pressure several times on different occasions to confirm whether or not you have high blood pressure.
Normal to high: between 120/80 and 140/90 mmHg.
National Heart Foundation guide to blood pressure ranges Your health professional will determine your ideal blood pressure goal based on your individual circumstances (including age, medical and family history and medicines). There is no firm rule that defines when blood pressure is too high for a particular person, but for most people the lower the better. In most cases a person is considered to have high blood pressure if their readings are consistently above 140/90 mmHg.
