What are warning signs of high blood pressure?

High blood pressure is often called the "silent killer" because it typically has no obvious symptoms, which is why regular monitoring is so important. However, when blood pressure reaches dangerously high levels, some people may experience severe headaches, dizziness, blurred or double vision, nosebleeds, shortness of breath, chest pain, or a pounding sensation in the chest, neck, or ears. Feeling flushed, having difficulty sleeping, or experiencing fatigue can also occur. These symptoms are more associated with hypertensive crisis, where readings exceed 180/120 mmHg, which requires immediate medical attention. Since most people with high blood pressure feel completely normal, the only reliable way to detect it is through regular blood pressure checks.
