Signs and Symptoms
In most people, high blood pressure rarely causes any signs or symptoms. Many times it will only become apparent during a routine health checkup. Rarely, even when levels are life-threatening, high blood pressure may cause only a few symptoms such as headaches, dizziness, or frequent nosebleeds.
For this reason, hypertension is known as the "silent killer," quietly increasing the risk of developing stroke, heart disease, heart attack, kidney damage, and blindness. The greater the blood pressure for extended periods, the greater the potential for damage. That is why it is important to be checked on a regular basis.
