Which statement best describes primary (essential) hypertension?

• A. It has no identifiable cause.
• B. It is often caused by kidney disease.
• C. It is primarily defined by diastolic pressure alone.
• D. It responds best to short-term interventions only.

Answer: (A)

Primary hypertension is high blood pressure with no single identifiable cause. Most cases arise from a mix of genetic and lifestyle factors—such as age, family history, obesity, high salt intake, physical inactivity, and stress—so there isn’t one disease or condition to target. Management focuses on long-term risk reduction through sustained lifestyle changes and, when needed, ongoing antihypertensive therapy. This differs from secondary hypertension, where high blood pressure comes from an identifiable underlying condition (like kidney disease) and addressing that cause can relieve the hypertension. It isn’t defined by diastolic pressure alone, since elevated blood pressure involves both systolic and diastolic readings, and it isn’t something treated effectively only in the short term; many people require ongoing management to control it.
