pressure. During the day, the blood pressure fluctuates due to
changes in activity and stress levels. These fluctuations are
normal.
Blood pressure is too high if, at rest, the diastolic pressure is
higher than 90 mmHg and/or the systolic blood pressure is higher
than 140 mmHg. Blood pressure is too low if, at rest, the diastolic
pressure is lower than 60 mmHg and/or the systolic blood
pressure is lower than 105 mmHg. Long-term values at these
levels may endanger your health because of the continuing
damage to the blood vessels in your body. However, only a
doctor can correctly interpret your blood pressure.
Even with normal blood pressure values, a regular self-check with
your blood pressure monitor is recommended. By doing this you
can detect possible changes in your values early and react
appropriately.
If you are undergoing medical treatment to control your blood
pressure, keep a record of the level of your blood pressure by
carrying out regular self-measurements at specific times of the
day. Show these values to your doctor.
Never use the results of your measurements to alter the drug
doses yourself that were prescribed by your doctor.
