Because of the silent and insidious way it works in the background i.e. no symptoms it is referred to as the Silent Killer. If left uncontrolled or untreated then High Blood Pressure can cause a variety of illnesses all of which could kill if left to their own devices.



In the United States of America alone their estimate to be 50 million sufferers of High Blood Pressure. It would appear in certain cases but there are greater percentage of sufferers of high blood pressure amongst the black community as opposed to those in the white or Hispanic community in the USA

Also, the consequences of high blood pressure are worse for blacks.High blood pressure occurs more often in older people-in about three fourths of women and almost two thirds of men aged 75 or older, compared with only about one fourth of people aged 20 to 74.

For those suffering with clinical obesity the incidences of high blood pressure rise by 200%.

It is a staggering figure that possibly only two thirds of the potential high blood pressure sufferers in the US have been diagnosed. Of this figure about three quarters are receiving medical treatment and of this first three quarters only 50% are receiving adequate treatment.

Two terms are used when calculating high blood pressure, the systolic which is the first and greater of the two figures and refers to the highest pressure of the Arteries. The diastolic figure is the second figure calculated and represents the pressure in the hall product to the process of contraction again.

Blood pressure is written as systolic pressure/diastolic pressure-for example, 120/80 mm Hg (millimetres of mercury). This reading is referred to as "120 over 80."High blood pressure is defined as a systolic pressure at rest that averages 140 mm Hg or more, a diastolic pressure at rest that averages 90 mm Hg or more, or both.

However, the higher the blood pressure, the greater the risks-even within the normal blood pressure range-so these limits are somewhat arbitrary. The limits were established because people with blood pressure above these levels are at increasing risk of complications.

In most people with high blood pressure, both systolic and diastolic pressures are high. The exception is older people who commonly have high systolic pressure (140 mm Hg or more) with normal or low diastolic pressure (less than 90 mm Hg).

This disorder is called isolated systolic hypertension. Blood pressure that is more than 180/110 mm Hg and does not produce any symptoms is " a hypertensive urgency.

Where the blood pressure is particularly severe and in excess of 210/120 mm Hg then the condition is deemed to be known as malignant hypertension. This has only been found to occur in about one half of one percent of all sufferers.

For some apparent reason that is not necessarily had an adequate medical explanation the incidences of malignant hypertension are increased within the black community and those within the lowest socioeconomic groups. This type of hypertension is unlike hypertensive urgency in that it produces a variety of severe symptoms. These can be fatal within a period of six months if left untreated.
