Hypotension or Low blood pressure is a reading of 90/60mmHg or less. It does not always cause symptoms, but you may need treatment if it does. Get your blood pressure checked if you keep getting symptoms like lightheadedness or dizziness, sick feeling, blurred vision, generally feeling weak, confusion, fainting. This might mean your blood pressure is too low. If you get symptoms when you stand up or suddenly change position, you may have postural hypotension.

You can check your blood pressure by asking if your pharmacist can do it, by asking your practice nurse or GP to do it or at home yourself using a home blood pressure monitor (which you can purchase from your local pharmacy). Low blood pressure is a measurement of 90/60mmHg or lower.

Treatment for hypotension or low blood pressure depends on the cause. If a cause can be found, your GP will be able to recommend treatment to ease your symptoms. For example, they may suggest changing medicines or altering your dose, if this is the cause or wearing support stockings – this can improve circulation and increase blood pressure. Medicine to increase blood pressure is rarely needed because simple lifestyle measures or treating the underlying cause is usually effective.
