IN BLOOD PRESSURE
All physical activities, agitation, stress, eating, drinking, smoking,
body posture and many more (including the blood pressure
measurement itself), affect the pressure values. For these reasons,
it is basically impossible to have identical values when several
measurements are taken.
Blood pressure fluctuations occur continuously during the day and
night.
Normally, the values are higher during the day and lower during
the night. The pressure values normally start to rise at around 3
a.m. and reach maximum level during the day in the waking and
activity hours.
For this reason, it is advised to measure the pressure at around the
same time every day.
HYPERTENSION IN ADULTS
The prescriptions for hypertension in adults are established by
WHO, the World Health Organisation.
Some predisposing factors like diabetes, obesity, smoking and old
age can contribute to the development of hypertension.
Arterial hypertension is defined "essential" in 90% of cases and
"secondary" in 10% of cases, when it is a consequence of chronic
kidney diseases or endocrine diseases.
It is asymptomatic and does not cause any significant disturbance
but in time, it damages the blood vessels and the vital organs
(heart, brain, kidney) with serious health consequences.
