Normal High Blood Pressure?
Base on standars recommended by the World Health Organization (WHO), the highest blood pressure still considered normal for health adults (those above 15 years old) is 40/90.
For those 50 years old and above, the maximum normal blood pressure may be a little higher, like 160/95.
High Blood Pressure?
High blood pressure or hypertension means that as blood flows, too much force is exerted on the arteries. The arterial walls are taut, making it harder for blood to pass through.
Borderline high blood pressure exists when an adult’s blood pressure goes above 140/90 and persists at the level, but does not go beyond 160/95.
When the blood pressure is persistently equal to or higher than 160/95, a state of definite high blood pressure is said to exist.
At least three successive readings on different days must be made before a person is diagnosed as having high blood pressure ( or hypertensive). This is because the blood pressure may fluctuate. One’s elevated blood pressure reading does not make a diagnosis of high blood pressure.
Causes High Blood Pressure?
More than 90 percent of persons with high blood pressure have what is called essential hypertension. This means that the cause is unknown.
But there are some risk factors that make a person more prone to hypertension. These are:
1. cigarette smoking
2. overweight
3. too much tension or stress
4. lack of exercise
5. eating too much salt and fatty foods
6. drinking too much alcohol/liqiuor
7. family history of hypertension and hear disease
8. diabetes (mellitus)
9. taking contraceptive pills (in some women)
Most of thses factors are within one’s control. A person would do well to avoid them to prevent hypertension. Seconday hypertension can be cured if the disease or abnomality causing it is cured or remedied.
The effects of High Blood Pressure?
High blood pressure makes the heart work harder than usual so that the blood can flow freely through the arteries. If untreated, hypertension forces the heart to enlarge. In time, the heart weakens. The end result is heart failure.
Hypertension speeds up hardening of the arteries (arteriosclerosis), and the formation of fatty deposits in the arteries inner layers (atherosclerosis). These block blood flow in the arteries, depriving organs of their blood supply.
The three vital organs especially vulnerable to the bad effects of high blood pressure are the heart, the brain and the kidneys.
Untreated hypertension thus contributes to heart attacks, strokes and kidney failure.
In view of its danger, all high blood pressure cases must be treated by a doctor without delay.
The symptoms of High Blood Pressure
High blood pressure has been aptly called the “silent killer” because a person usually has it without showing any symptoms until quite late.
Symptoms, if they do show, may include headache, pain in the back of the neck, dizziness. Sometimes flushing of the face, ringing in the ears, thumping in the chest and frequent nosebleeds. But these symptoms may develop slowly, and they are associated with diseases other than high blood pressure.
