Why High Blood Pressure is a "Silent Killer"
High blood pressure is often called the “silent killer”
Most of the time, high blood pressure, or hypertension, has no obvious symptoms to indicate that something is wrong. The best ways to protect yourself are being aware of the risks and making changes that matter.
A few facts to be aware of:
- Many people with high blood pressure don’t even know they have it. Often the signs and symptoms are misunderstood.
- High blood pressure develops slowly over time and can be related to many causes.
- High blood pressure cannot be cured. But it can be managed effectively through lifestyle changes and, when needed, medication.
