Common Diseases & Illnesses: ( Blood Pressure )


Blood Pressure is the pressure exerted by the blood on the walls of the blood vessels. Unless indicated otherwise, blood pressure is understood to mean arterial blood pressure, i.e. the pressure on the large arteries. The pressure of blood in other vessels is lower than arterial pressure.

The peak pressure in the arteries during the cardiac cycle is the systolic pressure, and the lowest pressure is the diastolic pressure. Typical values of blood pressure of a healthy adult are approximately 120/80 mmHg. Blood pressure is not static.

Normal ranges for blood pressure in adult humans are:

*Systolic between 90 & 135 mmHg
*Diastolic between 50 & 90 mmHg
Normal ranges observed in children are lower, and in the elderly, higher.


High blood pressure, called arterial hypertension, exerts mechanical stress on the arterial walls which leads to unhealthy tissue growth (atheroma). The higher the pressure, the more atheroma tends to progress. Low blood pressure, called hypotension, may be a sign of severe disease and should be paid close attention to. When blood pressure or flow of blood is low, the brain's blood supply is not sufficient causing dizziness, lightheadedness, weakness and even fainting.



There are many physical factors that can influence blood pressure and each of them may in turn be influenced by physiological factors, such as diet, exercise, disease, drugs, etc. Some possible physical factors follow:


*The rate of cardiac output. The harder the heart rate, the higher the blood pressure.
*The amount of blood present in the body. The more blood, the higher the pressure. Some   research indicates that there is a relationship between dietary salt intake and blood volume.
*Size and smoothness of blood vessel walls. This is called resistance. The higher the resistance,   the higher the blood pressure. Lower resistance; lower blood pressure.
*Blood thickness. The thicker the blood, the higher the blood pressure. Certain medical   conditions can change the thickness of the blood.
*Blood pressure can temporarily drop quickly when someone stands up from a sitting position.
*Toxins, including toxins from blood pressure medicines
*Hormonal abnormalities
*Shock
*Ailments such as Sepsis or Hemorrhages
