Which of the following factors can contribute to high blood pressure?

• A. Diet
• B. Age
• C. Genetics
• D. Physical Activity

Answer: (C)

Genetics can predispose someone to high blood pressure by shaping how the body regulates fluids, salts, and blood vessel tone. Inherited differences can affect kidney sodium handling, the hormones that control blood pressure, and the flexibility of artery walls. Because these genetic factors contribute to baseline risk, they can raise blood pressure even before lifestyle factors come into play, and a family history is a strong predictor of risk.

Diet, age, and physical activity also influence blood pressure. A high-sodium diet or poor overall diet can raise pressure; aging tends to stiffen vessels and raise risk; regular physical activity typically helps lower blood pressure. However, genetics helps explain why some individuals develop hypertension despite similar or even favorable lifestyles, making it a fundamental contributor to the condition.
