There are two major types of hypertension
-Primary, Essential or Benign Hypertension
The Primary, essential or benign hypertension is the commonest form of high blood pressure
It accounts for about 80 - 90 percent of all the diagnosed cases of high blood pressure around the world.
The cause of the primary, benign or essential hypertension (HTN) is mostly unknown. It is common amongst those, whose parent(s) also has the disease.
Even though, the cause of benign hypertension is unknown, there are some risk factors or rather certain circumstances that contribute to someone developing this kind of high blood pressure
Secondary hypertension is the type of high blood pressure in which the actual CAUSE is known.
Secondary HTN, accounts for about 5 - 10 percent, of all diagnosed cases of this disease.
As the name implies, it is "Secondary" to a pre-existing medical condition... like:
High blood pressure can also be classified according to its duration.
The two main types according to duration are:
Acute hypertension (HTN) is a medical condition in which the blood pressure becomes very high within short period of time.
Characteristics of an Acute HTN :
The treatment for acute HTN is usually very aggressive in nature to avert complications and further damage to the target organs like the eyes, kidneys... etc.
Chronic Hypertension is the direct opposite of acute HTN, in which the blood pressure is abnormally high, (i.e., over 140/90 mmHg) over a period of time... it may be months or years.
Usually, the precursor of chronic high blood pressure is prehypertension
People with Chronic HTN are also generally referred to as being... hypertensive
Chronic HTN usually has no symptoms in majority of cases.
Someone once asked... IS HIGH BLOOD PRESSURE A CHRONIC DISEASE? Yes it is...!!!
These types are categorized in Stages of Hypertension
This is based on the latest and newest (2014) JNC 8 and previous JNC 7 guidelines. According to the Eighth report of the Joint National Committee (JNC)... in the United States of America.
It is very important for you to know, how high blood pressure are categorized where you live, and the medical advisory organization responsible for regulating it.
STAGE 1 : Systolic 140 - 159 and Diastolic 90 - 99 mmHg
STAGE 2 : Systolic > 160 and Diastolic > 100 mmHg

Stage 3 Hypertension is phased out
There is NO Stage 3 high blood pressure according to JNC 8 and JNC 7.... Stage 3 hypertension, has been phased out since 2003.
High blood pressure classification according to location or when it occurred includes:
White coat hypertension.... which occurs when patient visits their physician
Occular ....... which is elevated pressure in the eyes
Different types of elevated blood pressure in / during pregnancy... like preeclampsia and gestational high blood pressure
Intra-cranial...... abnormally high pressures within the skull
Pulmonary ........ abnormally high pressures within the blood vessels, in the lungs.
There are much more classifications... if any medical professional, (doctors, medical specialists, nurses etc.) uses any new name, term or classification, that you are not familiar with, or you have recently been diagnosed with high blood pressure, ask... to ensure, you know the specific kind you have, in order to obtain the accurate and appropriate care and management .. they will be more than happy to explain it all to you.
Hopefully, these explanations clarifies the different types of hypertension that affect the human body.
