HIGHBLOOD PRESSURE: CAUSES, SYMPTOMS AND TREATMENT
According to the British Heart Foundation, as many as 7 million people in the UK are living with undiagnosed high blood pressure (hypertension). Concerned you may be at risk? We spoke with Dr Andrew Thornber, Chief Medical Of cer at Now Patient, to uncover the facts about high blood pressure. WHAT IS CLASSED AS HIGH BLOOD PRESSURE? Your blood pressure is measured in millimetres of mercury (mmHg) and consists of two numbers: the higher number refers to systolic pressure. This is the force with which your heart pumps blood around your body. The lower number refers to diastolic pressure. This is the resistance to the blood Flow in your blood vessels. Normal blood pressure is considered to be a reading between 90/60mmHg and 120/80mmHg. ‘The only way to know whether you have high blood pressure is to have it measured,’ says Dr Thornber. ‘Your GP will probably be concerned if your blood pressure reading is 140/90mmHg or higher.’ WHAT CAUSES HIGH BLOOD PRESSURE?
