There are a number of causes of
hypertension, these include...
Age. Over
time, the number of collagen fibers
in artery and arteriole walls
increases, making blood vessels
stiffer. With the reduced
elasticity comes a smaller
cross-sectional area in the artery
and so increased blood
pressure.
High salt
intake
Sedentary
lifestyle
Tobacco
smoking
Alcoholism
High levels of
saturated fat in the diet
Obesity - In
obese subjects, losing a kilogram
of mass generally reduces blood
pressure by 2 mmHg.
Stress
Low birth
weight
Diabetes
mellitus
Various
genetic causes
Occupational,
aircraft and roadway noise
exposure.
