Your health care team can
diagnose high blood pressure. They can also make treatment
decisions by reviewing your systolic (first number) and
diastolic (second number) blood pressure levels and comparing
them to guidelines.
Most health care professionals will use these guidelines from the ACC and AHA to
diagnose high blood pressure:If a health care professional diagnoses you with high blood pressure, talk with
your health care team about your blood pressure levels and how they affect your
treatment plan.
Learn how and where to measure
your blood pressure and why it's important to know your numbers.
Signs and symptoms
High blood pressure usually has no warning signs or symptoms,
and many people do not know they have it. Measuring your blood
pressure is the only way to know whether you have high blood
pressure.
Causes
There are several causes of and risk factors for high blood
pressure. Fortunately, you can control many of them.
High blood pressure usually develops over time. It can occur
because of unhealthy lifestyle choices, such as not getting
enough regular physical activity.
Certain health conditions, such as diabetes and obesity, can
also increase the risk for developing high blood pressure. And
high blood pressure can occur during pregnancy.
People who have depression, anxiety, stress, or post-traumatic
stress disorder over a long period of time may develop other
health problems, including an increased heart rate and high
blood pressure.
Other risk factors, such as family history and the environment,
can also increase a person's risk for high blood pressure.
Potential problems having high blood pressure could cause
High blood pressure can damage your health in many ways. It can
seriously hurt important organs like your heart, brain, kidneys,
and eyes.
The good news is that, in most cases, you can manage your blood
pressure to lower your risk for serious health problems.

High blood pressure (hypertension) complications can damage
your health in many ways, including harming organs such as
your heart, brain, and kidneys.
Heart attack and heart disease
High blood pressure can damage your arteries by making them less
elastic. This decreases the flow of blood and oxygen to your
heart and leads to heart disease.
In addition, decreased blood flow to the heart can cause:
- Chest pain, also called angina.
- Heart attack, which happens when the blood supply to
your heart is blocked and heart muscle begins to die without
enough oxygen.
- The longer the blood flow is blocked, the
greater the damage to the heart.
- Heart failure, a condition that means your heart can't
pump enough blood and oxygen to your other organs.
Stroke and brain problems
High blood pressure can cause the arteries that supply blood and oxygen to the
brain to burst or be blocked, causing a stroke.
Brain cells die during a stroke because they do not get enough oxygen. Stroke
can cause serious disabilities in speech, movement, and other basic activities.
A stroke can cause death. Having high blood pressure, especially in midlife, is linked to having poorer
cognitive function and dementia later in life.

high blood pressure and dementia from the National Institutes of Health's Mind
Your Risks campaign.
Heart valve disease
High blood pressure can cause heart valve disease, which is when any valve in
the heart is damaged or diseased.
Kidney disease
Adults with diabetes, high blood pressure, or both have a higher
risk of developing chronic kidney disease than those without
these conditions.

the kidney disease information page.
Prevention
No matter your age, you can take steps each day to keep
your blood pressure in a healthy range.
Many people with high blood pressure can lower their blood
pressure into a healthy range or keep their numbers in a healthy
range by making lifestyle changes.
Talk with your health care team about:
- Physical activity each week (about 30 minutes a day, 5
days a week)
- Not smoking
- Eating a healthy diet, including limiting sodium (salt)
and alcohol
- Keeping a healthy weight
- Managing stress
In addition to making positive lifestyle changes, some people
with high blood pressure need to take medicine to manage their
blood pressure.
Talk with your health care team right away if:
-
You think you have high blood pressure.
-
If you've been told you have high blood pressure but do not
have it under control.
By taking action to lower your blood pressure, you can help
protect yourself against heart disease and stroke, also called
cardiovascular disease (CVD).
