High blood pressure is often called the 'silent killer' because it usually has no symptoms. You can have it for years without knowing. That's why regular blood pressure checks are so important, even if you feel fine. Some people may experience headaches, shortness of breath, or nosebleeds, but these usually don't occur until blood pressure has reached dangerously high levels.

Uncontrolled high blood pressure can lead to serious health problems. It puts extra strain on your heart and blood vessels, increasing your risk of heart attacks, strokes, and kidney disease. Over time, it can also cause vision problems and dementia. The good news is that high blood pressure can be controlled with lifestyle changes and medication.

Blood pressure is measured using two numbers. The top number (systolic) measures the pressure when your heart beats. The bottom number (diastolic) measures the pressure when your heart rests between beats. A normal blood pressure is generally considered to be below 120/80 mmHg. Anything above 130/80 mmHg is considered high.

High blood pressure is serious, but it's also manageable with proper care and attention.
