High Blood Pressure Overview and Diagnosis High blood pressure is a risk factor for many serious heart conditions, including heart attack and stroke, but can usually be well-controlled through diet and a healthy lifestyle.
Many people do not know they have high blood pressure, as it often has no obvious symptoms. Having your blood pressure checked is the only way to know whether it is in a normal or unhealthy range. Regular monitoring can help you tell if you have high blood pressure and notice changes over time.
Sometimes high blood pressure is the result of another condition, including kidney or thyroid problems, certain medications, and congenital heart defects. Called “secondary hypertension,” this type of high blood pressure often has a sudden onset and can cause blood pressure to rise higher than it otherwise would.
