and 159 mmHg and/or the diastolic blood pressure values are
between 90 mmHg and 99 mmHg, consult your physician.
Regular self-checks are necessary.
If you have blood pressure values that are too low (i.e., systolic
values under 105 mmHg and/or diastolic values under 60
mmHg), consult your physician.
Even with normal blood pressure values, a regular self-check
with your blood pressure monitor is recommended. 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 values along with time of day and
date. Show these values to your physician. Never use the
results of your measurements to independently alter the
medication prescribed by your physician.
