Low blood pressure when standing up or changing position suddenly is known as postural hypotension.
Low blood pressure is considered to be a reading of less than 90/60mmHg.
Blood pressure can be checked by a practice nurse, a GP, a pharmacist or at home with a suitable blood pressure monitor.
Anyone who keeps getting symptoms such as dizziness and fainting should see their GP for further advice.
People aged 40 to 74 are also able to have their blood pressure checked every five years with the NHS Health Check.
