Which of the following are the two primary types of hypertension?

The identification of the two primary types of hypertension centers on their underlying causes. Essential (primary) hypertension is the most common form, accounting for the majority of hypertension cases. This type of hypertension does not have a specific identifiable cause; rather, it arises from a complex interplay of genetic, environmental, and lifestyle factors.

Secondary hypertension, on the other hand, occurs as a result of an identifiable underlying condition, such as kidney disease, hormonal disorders, or certain medications. Identifying and addressing the root cause of secondary hypertension can often effectively control or even resolve the elevated blood pressure.

The other options introduce classifications of hypertension that do not represent the two primary categories. Tertiary hypertension is not a recognized classification, malignant hypertension is a severe form of hypertension that needs immediate treatment but is not a primary type, and transient hypertension is an episodic condition rather than a distinct category. Understanding these distinctions is crucial for effective diagnosis and management of hypertension in clinical practice.
