High Blood Pressure
High blood pressure (hypertension) means the pressure in your arteries stays higher than the usual range over time. It often causes no symptoms and is usually identified through routine measurement.
What is it?
Blood pressure is recorded as two numbers. When readings stay raised across several properly taken measurements, a healthcare professional may describe this as hypertension.
Common risk factors
- Higher salt intake
- Low physical activity
- Excess weight
- Regular heavy alcohol use
- Family history
- Increasing age
Possible symptoms
Most people have no symptoms. Some may notice headaches or visual changes, but these are not reliable indicators and can have many other causes.
Prevention and lifestyle
- Reducing added salt
- Regular movement across the week
- Sleep and stress recovery
- Limiting alcohol
Diagnosis
Assessment usually involves repeated readings, sometimes with home or ambulatory monitoring, alongside a review of overall cardiovascular risk.
Treatment overview
Management may combine lifestyle measures with medication where a clinician considers it appropriate. Decisions are individual.
