Define the health issue (the impact on the body)
Hypertension is sustained elevation of resting systolic BP (≥ 140 mm Hg), diastolic BP
(≥ 90 mm Hg), or both.
High blood pressure is a common condition in which the force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease.
Blood pressure is determined by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure.
Hypertension can continue for years without any symptoms. Even without symptoms, damage to blood vessels and the heart continues and can be detected. Uncontrolled high blood pressure increases the risk of serious health problems, including heart attack and stroke. 2.
Define symptoms
Most people with high blood pressure have no signs or symptoms, even if blood pressure readings reach dangerously high levels.
Although a few people with earlystage high blood pressure may have dull headaches, dizzy spells or a few more nosebleeds than normal, these signs and symptoms usually don't occur until high blood pressure has reached a severe or lifethreatening stage.

Define cause
There are two types of high blood pressure.
Primary (Essential) Hypertension
For most adults, there's no identifiable cause of high blood pressure. This type of high blood pressure, called essential hypertension or primary hypertension, tends to develop gradually over many years.
Secondary Hypertension
Some people have high blood pressure caused by an underlying condition.
This type of high blood pressure, called secondary hypertension, tends to appear suddenly and cause higher blood pressure than does primary hypertension. Various conditions and medications can lead to secondary
hypertension,
