“One of the most dangerous things about hypertension – or high blood pressure – is that you may not know you have it,” it said.
“In fact, nearly one-third of people who have high blood pressure don’t know it. That’s because high blood pressure doesn’t have any symptoms unless it’s very severe.
“The best way to know if your blood pressure is high is through regular checkups.
“If you have any of these symptoms, see a doctor immediately. You could be having a hypertensive crisis that could lead to a heart attack or stroke.”
