The first step in preventing and controlling high blood pressure is to learn the answers to a few questions, such as:
What is high blood pressure, and what happens in a person's body that makes it dangerous?Over time, if the force of the blood flow is often high, the tissue that makes up the walls of arteries gets stretched beyond its healthy limit. This creates problems in several ways.
What do the numbers in a blood pressure reading mean?The two numbers tell you the amount of force pushing against your artery walls when the heart is contracting and when the heart is at rest.
When does HBP require emergency medical treatment?High blood pressure often does its damage without creating symptoms, but when blood pressure numbers rise above 180 for the systolic pressure or 110 for the diastolic pressure, you need emergency treatment.
When is blood pressure too low?Although it is possible that low blood pressure can alert you to a problem, it is usually only dangerous if it causes notable signs and symptoms.
