High
Blood Pressure: Study
Blood pressure is the force of the blood pushing against
the walls of the arteries. Blood pressure is the result of two forces:
from the heart as it pumps blood into the arteries and throughout the
circulatory system, and the force of the arteries as they resist blood
flow. Blood pressure is measured by putting a blood pressure cuff
around your arm, inflating the cuff and listening for the flow of
blood. Blood pressure is always given as these two numbers, the
systolic and diastolic pressures. Blood pressure is traditionally
measured with a device called a sphygmomanometer. Blood pressure is
measured in millimeters of mercury (mm Hg). Blood pressure is
generally felt to be abnormally high at a level of 140/90, and some
sort of definitive therapy and follow-up should be started at this
level. High blood pressure is called the silent killer because it
usually has no symptoms. Blood is carried from the heart to all
parts of your body in vessels called arteries. Blood does not flow
regularly like water from a tap:-When the heart contracts (systole),
the blood is propelled into the main arteries that act as a
pressurized reservoir. Pressure in a hose can be regulated either by
controlling the rate at which fluid passes through it or by widening
it. Pressure inside your arteries can cause the muscles that line the
walls of the arteries to thicken. Your blood pressure is at its
highest when the heart beats, pumping the blood. When the heart is at
rest, between beats, your blood pressure falls. Still, for most of
your waking hours, your blood pressure stays pretty much the same when
you are sitting or standing still. Heart disease is the UK’s biggest
killer, claiming thousands of lives each year. Heart failure is when
your heart cannot pump blood around the body as well as it should, and
this can cause you to become short of breath and can cause your ankles
to swell. Heart attack High blood pressure is a major risk factor for
heart attacks.
Various disorders and drugs can cause the compensatory mechanisms
to malfunction, and high blood pressure may result. Causes In most
instances of high blood pressure, no known cause can be identified.
Doctors do not know what causes high blood pressure in 90 to 95
percent of people who have it. For some people, just being in a
medical setting causes their blood pressure to rise.

Symptoms
Symptoms When blood
pressure is too low, the first organ to malfunction is usually the brain.
Symptoms that may occur include: Confusion Chest pain Ear noise or buzzing
Irregular heartbeat Nosebleed Tiredness Vision changes. What is treatment,
medication, medicines, remedy, drugs, cure of lowering high Blood pressure
or Hypertension? . Although high blood pressure, also known as
hypertension, can cause headaches, dizziness and problems with vision, the
majority of people with the condition do not display any noticeable
symptoms. Treatment
Treatment is focused on reducing water retention and lowering blood
pressure to normal limits. Treatment for high blood pressure depends on
the severity of the disease and whether you have other health problems,
such as heart failure or diabetes, or you are pregnant. Treatment of
primary high blood pressure, especially moderate or severe high blood
pressure, decreases the risk of heart failure, coronary artery disease,
heart attack, abnormal heartbeats, stroke, and kidney disease, and reduces
the risk of death from these conditions. Treatment for high blood pressure
must be highly individualized and based on your risk factors, such as
diabetes, smoking, and heart disease. Treatment when blood pressure
increases slightly and the woman is not near the end of her pregnancy, bed
rest may help reduce the pressure. Treatment begins with changes you can
make in your lifestyle to help lower your blood pressure and reduce your
risk of heart disease.
High blood pressure is called the silent killer because it usually has
no symptoms. When high blood pressure is not found and treated, it can
cause: The heart to get larger, which may lead to heart failure. If your
blood pressure is in the pre hypertension range, it is more likely that
you will end up with high blood pressure unless you take action to prevent
it. High blood pressure is dangerous because it makes the heart work too
hard and contributes to atherosclerosis (hardening of the arteries). If
your blood pressure is between 120/80 mmHg and 139/89 mmHg, then you have
pre hypertension. The good news is that if your blood pressure is high, it
can be lowered by making changes to your lifestyle, for example changing
your diet, exercising and losing weight, and when needed, with tablets. |
