High blood pressure, or hypertension, typically has an insidious onset. What does the term insidious indicate?

The term 'insidious' indicates a gradual or subtle onset with no obvious symptoms of a disease. In the context of high blood pressure, this means that hypertension can develop over time without noticeable signs, making it important to monitor blood pressure regularly even in the absence of symptoms. Individuals with hypertension may not experience overt symptoms until significant damage has occurred, highlighting the importance of early detection through routine screenings and monitoring to prevent complications.
