What is Hypertension?
High blood pressure is defined as a blood pressure greater than 140/90 millimeters of mercury (mmHg).

Most cases of high blood pressure (about 85% to 90%) are referred to as essential or primary hypertension.  By definition, essential hypertension has no identifiable cause.

Hypertension (HTN or HT), otherwise referred to as high blood pressure (HBP), is a long-term medical condition in which the blood pressure in the arteries is persistently gets elevated.

High blood pressure typically does not cause symptoms. Long-term high blood pressure, however, is a major risk factor for coronary artery disease, stroke, heart failure, atrial fibrillation, peripheral vascular disease, vision loss, chronic kidney disease, and dementia.

After a recent study, The World Health Organization (WHO) made a claim that the growth of the processed food industry and the consumption of processed industry product has impacted the amount of salt in diets worldwide, and that this plays a role in hypertension.

Unfortunately, the cause of high blood pressure (hypertension) in 90-95% of the cases is unknown. There are, however, a number of factors that have been linked to high blood pressure including:

A family history of high blood pressure.
Age – The incidence of high blood pressure rises in men after age 35 and in women after age 45.
Gender – Men are more likely to have high blood pressure than women.
Smoking – If you smoke cigarettes, you may have increased high blood pressure.
Race – Approximately 33% of African-Americans have high blood pressure, compared to 25% of Caucasians.

Definition Of Terms
What Is Blood Pressure?
Blood pressure is the force exerted by the blood against the walls of the blood vessels. The pressure depends on the work being done by the heart and the resistance of the blood vessels.

What Are Arteries?

Your arteries and high blood pressure. 

The arteries are the large blood vessels that carry blood from the heart to all the organs and muscles of the body, to give them the energy and oxygen they need. The arteries manage the flow of blood by controlling the speed and direction it flows in.

What is Coronary artery disease?
This is the impedance or blockage of one or more arteries that supply blood to the heart, usually due to atherosclerosis (hardening of the arteries). Abbreviated CAD. A major cause of illness and death, CAD begins when hard cholesterol substances (plaques) are deposited within a coronary artery.

FAQs Associated With Hypertension

What Causes Primary Hypertension?
Primary hypertension has no clear cause and is thought to be linked to genetics, poor diet, lack of exercise and obesity

What causes Secondary Hypertension?
Secondary hypertension (secondary high blood pressure) is high blood pressure that's caused by another medical condition. Secondary hypertension can be caused by conditions that affect your kidneys, arteries, heart or endocrine system. Secondary hypertension can also occur during pregnancy. In this type of hypertension, once the root cause is treated, blood pressure usually returns to normal or is significantly lowered.

What Is Atherosclerosis?
It is a condition where the arteries become narrowed and hardened due to a buildup of plaque around the artery wall. It is also known as arteriosclerotic vascular disease. The disease disrupts the flow of blood around the body, posing the risk of serious complications.

What Causes Atherosclerosis?
High blood pressure is a major cause of atherosclerosis, the artery-clogging process that leads to heart attacks and strokes.

What are Clogged Arteries?
Clogged arteries result from a buildup of a substance called plaque on the inner walls of the arteries. Arterial plaque can reduce blood flow or, in some instances, block it altogether.

Can Hypertension Be Cured?
Some high blood pressure could have surprising causes - and for one such cause, there's a surgical cure.
