What is high blood pressure?
You probably have high blood pressure (hypertension) if your blood pressure readings are consistently 140 over 90, or higher, over a number of weeks.You may also have high blood pressure if just one of the numbers is higher than it should be over a number of weeks.
If you have high blood pressure, this higher pressure puts extra strain on your heart and blood vessels. Over time, this extra strain increases your risk of a heart attack or stroke.High blood pressure can also cause heart and kidney disease, and is closely linked to some forms of dementia.

Measuring Blood Pressure
Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood. High blood pressure, sometimes called hypertension, happens when this force is too high. Health care workers check blood pressure readings the same way for children, teens, and adults. They use a gauge, stethoscope or electronic sensor, and a blood pressure cuff. With this equipment, they measure:
Systolic Pressure: blood pressure when the heart beats while pumping blood
Diastolic Pressure: blood pressure when the heart is at rest between beats

What are the signs and symptoms of high
blood pressure?
High blood pressure usually has no signs or symptoms, so the only way to know if you have high blood pressure is to have yours measured. However, a single high reading does not necessarily mean you have high blood pressure. Many things can affect your blood pressure through the day, so your doctor will take a number of blood pressure readings to see that it stays high over time.Occasionally people with very high blood pressure say they experience headaches, but it is best to visit your GP if you are concerned about symptoms.

Types of High Blood Pressure
There are two main types of high blood pressure: primary and secondary high blood
pressure.
Primary High Blood Pressure
Primary, or essential, high blood pressure is the most common type of high blood pressure.
This type of high blood pressure tends to develop over years as a person ages.
Secondary High Blood Pressure
Secondary high blood pressure is caused by another medical condition or use of certain
medicines. This type usually resolves after the cause is treated or removed.

What high blood pressure (hypertension) can do
High blood pressure (hypertension) puts extra strain on your heart and blood vessels. This can cause them to become weaker or damaged.
The higher your blood pressure, the higher your risk of serious health problems in the future. High blood pressure can affect your body in a number of ways:
Your heart: high blood pressure can cause you to have a heart attack. It can also cause heart failure.
Your brain: high blood pressure is a leading cause of strokes. It has also been closely linked to some forms of dementia.
Your kidneys: high blood pressure can cause kidney disease.
Your limbs: high blood pressure can cause peripheral arterial disease, which can affect your legs.
