High blood pressure

Hypertension

High blood pressure affects more than 1 billion people worldwide and is the commonest cause of cardiovascular disease

About

It’s not clear what causes high blood pressure. The vast majority of patients with hypertension display no symptoms and have what is called primary hypertension. This simply means that no underlying cause of the hypertension (such as an adrenal tumour or some form of kidney disease) can be explained.

Need to know

  • Symptoms of high blood pressure icon plus

    High blood pressure does not generally cause any symptoms. However, if it is very high, you may experience the following:

    • headaches
    • blurred or double vision
    • nosebleeds
    • shortness of breath
  • Diagnosis icon plus

    You will be asked to sit down on a chair with a back support and have your legs uncrossed prior to your blood pressure being taken. Your consultant will usually use an automatic device with a sensor to measure your blood pressure. If they decide to take your blood pressure using a pump and dial you will need to roll up your sleeve or remove any long-sleeved clothing so they can access your upper arm. If you are found to have hypertension your consultant will try to determine the underlying causes. They will undertake a comprehensive assessment of your future risk of developing cardiovascular disease such as stroke, heart attack or kidney failure.
  • Potential treatment options icon plus

    • Making healthy lifestyle changes such as lowering your salt intake, eating a balanced diet, being active, reducing your alcohol intake, losing weight if you're overweight, drinking less caffeine, not smoking and getting plenty of sleep every night.
    • Taking medication to lower your blood pressure. This may include ACE inhibitors, Angiotensin-2 receptor blockers (ARBs), calcium channel blockers, diuretics or beta-blockers.
