Blood pressure is the force or pressure which the blood exact on the wall of the blood vessels in which it is contained.
When this force or pressure is higher than normal constantly termed hypertension,
The normal blood pressure of an adult range from 120/180mmhg (millimeter per mercury)-140/90mmhg.
The heart is the organ which pumps blood around the body. The instrument for measuring blood pressure is known as a sphygmomanometer.
In blood pressure measurement there is systolic and diastolic (systolic is the contraction of the heart while the diastolic is when the heart relaxes between beats. The systolic is the upper figure while the diastolic is the lower figure. When the heart pumps blood to the lungs for oxygen and carries oxygenated blood to the muscle and cells this creates pressure.
Hypertension is a silent killer and a chronic disease. when blood pressure is higher than normal it causes damages to vital organs in the body and the blood vessels H.B.P (high blood pressure)can lead to heart attack, stroke, kidney failure, eye problem, and even death.
Types of hypertension
There are two common types of hypertension namely: essential or primary hypertension– In this type of hypertension the cause is not known it occurs suddenly though it can be triggered by some function such as diet, lifestyle, etc.
Secondary hypertension-This has an underlying cause usually a disease condition or abnormality in the arterial blood supply to the kidney. other types of hypertension include
Renal hypertension-this is also known as renovascular hypertension this is caused by kidney disease i.e. a person’s blood pressure becomes high as a result of kidney disease.
Malignant hypertension- This occurs suddenly and the blood pressure rises very fast diastolic rises over 130
Resistant hypertension-As the name implies this type of hypertension does not respond to drugs or treatment, it still remains high in spite of different anti-hypertensive drugs being administered.
Isolated systolic hypertension-In this type of hypertension the systolic is high while the diastolic may remain within the normal range as a result of the loss of the elasticity of the arteries.
