Quick answer
What is High blood pressure (hypertension)?
High blood pressure, or hypertension, means the pressure in the arteries stays higher than it should over time. It usually causes no symptoms, which is why it is often found at a routine check or pharmacy reading, and why it is sometimes called a "silent" condition.
- How it is treated: The aim is to bring blood pressure down to an agreed target and, just as importantly, to reduce overall cardiovascular risk.
- Self-care: Reducing salt, maintaining a healthy weight, regular physical activity, limiting alcohol, stopping smoking and managing stress all lower blood pressure and cardiovascular risk, and can reduce how much medication is needed.
- When to seek help: A very high reading with symptoms such as severe headache, chest pain, breathlessness, visual disturbance or weakness needs urgent medical assessment.
What it is
High blood pressure, or hypertension, means the pressure in the arteries stays higher than it should over time. It usually causes no symptoms, which is why it is often found at a routine check or pharmacy reading, and why it is sometimes called a "silent" condition. Left untreated, the sustained extra load damages blood vessels and organs, raising the long-term risk of stroke, heart attack, heart failure, kidney disease and vascular dementia. A diagnosis is normally confirmed with readings away from the clinic (home or ambulatory monitoring) rather than a single high reading, and treatment is guided by how high the pressure is and the person's overall cardiovascular risk.
How it is treated
The aim is to bring blood pressure down to an agreed target and, just as importantly, to reduce overall cardiovascular risk. Lifestyle measures come first and continue alongside any medication. When medicine is needed, treatment usually starts with a single agent and is built up in steps, combining drugs that work in different ways rather than pushing one to its limit. Which agent is chosen first depends on age, ethnicity, other conditions (such as diabetes or kidney disease) and whether the person could become pregnant. Treatment is reviewed and adjusted over time, with home readings and blood tests to check the kidneys and salts.

When to see a doctor
A very high reading with symptoms such as severe headache, chest pain, breathlessness, visual disturbance or weakness needs urgent medical assessment. Routine high readings without symptoms should be discussed with your GP or pharmacist.

Answers
High blood pressure (hypertension): frequently asked questions
What medicines are used for high blood pressure?
The main classes are ACE inhibitors, angiotensin-receptor blockers (ARBs), calcium-channel blockers and thiazide-type diuretics, with spironolactone often added for resistant cases and beta-blockers used where there is another reason for them. Treatment is usually built up by combining classes; the right combination depends on your age, background and other conditions.
Do I have to take blood-pressure medicine for life?
Often, yes — hypertension is usually a long-term condition and the benefit comes from sustained control. Some people who lose weight and change their lifestyle substantially can reduce or, occasionally, stop medication under medical supervision, but you should never stop on your own.
Why am I on more than one blood-pressure tablet?
Combining low doses of two or more medicines that work in different ways usually controls blood pressure more effectively, and with fewer side effects, than pushing a single drug to its maximum. This is a standard and deliberate approach.
Can lifestyle changes replace medication?
For mildly raised blood pressure, lifestyle change alone is sometimes enough. For higher readings or higher overall risk, medicines are usually needed as well — but lifestyle measures still matter because they improve control and lower risk.
