Key takeaway
Blood pressure is the force of blood pushing against the walls of your arteries.
What to know
- Your heart pumps blood through arteries to deliver oxygen and nutrients around your body.
- Some pressure is necessary, but pressure that remains too high can strain the heart and damage blood vessels.
- Blood pressure changes throughout the day, so repeated readings are more useful than one isolated result.
Take action
Describe blood pressure in your own words and record your latest reading if you have one.
Remember
Blood pressure is necessary. The risk comes when it stays too high for too long.
