Examination Overview
The extent of the physical examination and the level of detail in
your doctor's questions depend on how high your blood pressure is and whether
you have other risk factors for heart disease. People who have many risk
factors may have a more detailed evaluation.
The examination includes:
- Your medical history to evaluate risk
factors.
- Two or more blood pressure measurements. Measurements may
be taken from both the left and right arms and legs and may be taken in more
than one position, such as lying down, standing, or sitting. Multiple
measurements may be taken and averaged.
- Measurement of your weight
and height.
- Examination of the retina, the light-sensitive lining
at the back of the eye.
- A heart
examination.
- Examination of your torso, arms, and legs for fluid
buildup (edema), and the pulse in several areas, including the
neck.
- Examination of your abdomen using a stethoscope. A doctor
will listen to the blood vessels in the abdomen for abnormal sounds. These
sounds may be caused by rapid blood flow through a narrowed artery in the
abdomen (abdominal bruits).
- Examination of your neck for an
enlarged thyroid
, distended neck veins, and
bruits in the
carotid arteries.
Why It Is Done
The physical examination and medical history are done to:
- Confirm that you have high blood
pressure.
- Check for effects of
high blood pressure on organs such as the kidneys and
heart.
- Determine whether you have
risk
factors for
heart disease or
stroke.
- Rule out other causes of high
blood pressure (secondary hypertension), such as medicines or other medical
conditions.
Results
Blood pressure measurements are classified as follows.
Normal
- Systolic below 140 millimetres of mercury (mm
Hg)
- Diastolic below 90 mm Hg
High-normal
- Systolic 130–139 mm Hg
- Diastolic
85–89 mm Hg
High blood pressure (hypertension)
- Systolic 140 mm Hg or
above
- Diastolic 90 mm Hg or above
High blood pressure is also classified into stages.
- Stage 1 high blood
pressure:
- Systolic 140–159 mm
Hg
- Diastolic 90–99 mm Hg
- Stage 2 high blood
pressure:
- Systolic 160 mm Hg or
higher
- Diastolic 100 mm Hg or higher
Other examinations
The physical examination may look for evidence that high blood
pressure has already caused damage to blood vessels or other organs or for
signs of other disease. Your health professional may examine your:
If you have high-normal blood pressure or if high blood pressure is
diagnosed, lifestyle changes and/or drug treatment may be started.
You may need more tests to check for
secondary high blood pressure or damage to other
organs, such as the kidneys, if:
- You are young and your blood pressure is
160/100 mm Hg or higher.
- You had many treatments and medications
but your blood pressure is still 160/100 mm Hg or higher.
What To Think About
In most cases of high blood pressure, the person does not have any
signs of complications or secondary causes of high blood pressure.
Note: A diagnosis of high blood pressure
usually is based on an average of two or more readings taken during two or more
visits after an initial screening.
- Except in very severe cases, the diagnosis is
not based on a single reading.
- Two or more blood pressure
measurements, taken at follow-up doctor visits, may be needed to confirm an
initial high blood pressure reading.
- Single blood pressure readings
taken a week apart may vary, due to normal changes in blood pressure and to
differences in how it is measured.
