High Blood Pressure, the Insidious Killer
Next time you are with a group of 3 friends, take a good look
around; one of you will have high blood pressure. The sad part
is, since there are no symptoms, you may not even be aware of
it. Untreated high blood pressure can lead to heart attack,
congestive heart failure, stroke, or kidney failure. Various
risk factors contribute to this disease that are both under our
control, and out of our control. The only way to determine if
you have high blood pressure is to have your blood pressure
checked. The insidious nature of this disease makes it a true
Silent Killer.
The brain requires unobstructed blood flow to nourish its many
functions. Very high, sustained blood pressure will eventually
cause blood vessels to weaken. Over time these weaken vessels
can break, and blood will leak into the brain. The area of the
brain that is being fed by these broken vessels start to die,
and this will cause a stroke. Additionally, if a blot clot
blocks a narrowed artery, blood ceases to flow and a stroke will
occur. Symptoms of a stroke include sudden numbness or weakness
of the face, arm or leg, especially on one side of the body,
confusion, trouble speaking, or seeing, sudden severe headache.
If you or someone with you has one or more of these signs, don't
delay, call 911.
Like the brain, the heart requires blood to bring oxygen, and
nutrients to its muscle tissue. The narrowing of the arteries
due to blockage can cause high blood pressure. If this blockage
occurs in the arteries of the heart, coronary arteries, heart
muscle damage can occur, resulting in a heart attack. Some heart
attacks are sudden and intense, however most heart attacks start
slowly with mild pain and discomfort. Most heart attacks involve
discomfort in the center of the chest that lasts more than a few
minutes, or that goes away and comes back. It can feel like
uncomfortable pressure, squeezing, fullness or pain. Shortness
of breath may occur, as well as nausea, or lightheadedness. It
is vital to get help immediately if any of these symptoms occur.
The kidneys act as filters to rid the body of all waste
products. Eventually, high blood pressure can thicken, then
narrow the blood vessels of the kidneys. The kidneys becomes
less efficient, filtering less fluid, and waste builds up in the
blood. Over time, the kidneys may fail altogether. When this
happens, medical treatment such as dialysis, or a kidney
transplant may be needed.
The best way to find out if you have high blood pressure is by
having your blood pressure checked regularly. Generally
speaking, doctors will diagnose a person with high blood
pressure on the basis of two or more readings, taken on
different occasions. A consistent blood pressure reading of
140/90 mmHg or higher is considered high blood pressure, or
hypertensive. It is vital to take steps to keep your blood
pressure under control. The treatment goal is blood pressure
below 140/90 and lower for people with other conditions, such as
diabetes and kidney disease.
Adopting a healthy lifestyle including healthy eating habits,
reducing salt in the diet, maintaining a healthy weight,
limiting alcohol consumption, being physically active, and
quitting smoking is an effective step in preventing and
controlling high blood pressure. If lifestyle improvements alone
are not sufficient in keeping pressure controlled, it may be
necessary to add blood pressure medications. There are several
options that physicians have at their disposal, and each option
should be discussed, as to their side effects and efficacy.
