What defines a 'hypertension crisis'?

A hypertension crisis is specifically characterized by a severe increase in blood pressure, typically recognized as readings exceeding 180/120 mmHg. This level of hypertension is critical as it can lead to acute complications, including organ damage and other life-threatening conditions. The main concern during a hypertension crisis is the immediate risk it poses to vital organs, such as the heart, brain, kidneys, and eyes.

In contrast, a slight increase in blood pressure or a transient increase does not reach the severity necessary to be classified as a crisis. While readings of 140/90 mmHg or higher indicate elevated blood pressure and may warrant attention, they do not represent the high-risk scenario that characterizes a hypertension crisis. The distinction is crucial, as recognizing the signs and symptoms of a hypertension crisis can prompt timely medical interventions, potentially preventing serious health outcomes.
