What may be a symptom of severe hypertension?

Severe hypertension, or high blood pressure, often presents with a range of symptoms indicative of its potential health risks. Dizziness is a common symptom that can occur when blood pressure is significantly elevated. This happens because high blood pressure can lead to reduced blood flow to certain parts of the body, particularly the brain, which may result in feelings of lightheadedness or balance issues.

In contrast, the other options do not directly relate to the physiological effects of severe hypertension. Increased energy and enhanced appetite are typically not associated with high blood pressure; instead, hypertension can lead to fatigue and other health complications. Similarly, improved vision is not a symptom linked to severe hypertension; in fact, prolonged high blood pressure can potentially damage vision over time due to effects on the blood vessels in the eyes. Thus, dizziness is the symptom that aligns with the physiological impacts of severe hypertension.
