Acute hypertension, also known as a hypertensive crisis, is a sudden and severe increase in blood pressure. This condition can lead to serious health issues, including heart attack, stroke, or organ damage. Blood pressure readings of 180/120 mmHg or higher are typically considered acute hypertension, requiring immediate medical attention. The causes of acute hypertension can vary and may include stress, certain medications, or underlying health conditions such as chronic kidney disease or adrenal gland disorders. Treatment often involves medications to lower blood pressure quickly and safely, along with addressing any underlying causes.
