In most people with high blood pressure, there are ____________ signs or symptoms.

Individuals with high blood pressure, also known as hypertension, often do not exhibit any noticeable signs or symptoms. This condition is sometimes referred to as a "silent killer" because many people may be unaware they have it until they experience complications or undergo routine medical checks where blood pressure measurements are taken.

This absence of symptoms is particularly significant because it can lead to a false sense of security, allowing the condition to persist unchecked, potentially leading to serious health issues, such as heart disease or stroke, down the line.

In contrast, the other terms do imply more significant or apparent conditions. A deadly outcome would suggest that high blood pressure always leads to immediate health crises, which is not the case for most individuals who are unaware of their hypertension. Underlying conditions might indicate that hypertension is secondary to another illness, which does not apply to the most common type, primary hypertension. Similarly, severe signs or symptoms would suggest that hypertension almost always manifests with obvious physical markers, which is misleading, as many individuals remain asymptomatic.
