Symptoms (Warning Sign)
Most people with high blood pressure have no signs or symptoms, but people often think that headaches, dizziness or nosebleeds are common warning signs and symptoms of high blood pressure. It's true that a few people with early-stage high blood pressure have a dull ache in the back of their heads when they wake in the morning. Or perhaps they have a few more nosebleeds than normal.
Headaches, dizziness or nosebleeds typically don't occur until high blood pressure has reached a more advanced stage — one that's possibly life-threatening. Even so, most people with the highest blood pressure readings don't experience any of these symptoms.
Other signs and symptoms sometimes associated with high blood pressure generally are caused by other conditions that can lead to high blood pressure. Such signs and symptoms include:
- Excessive perspiration
- Muscle cramps
- Frequent urination
- Rapid or irregular heartbeat (palpitations)
