Q: What should I know about blood pressure? A: Blood pressure (BP) is a measurement of the pressure your blood puts on the walls of your arteries. Your BP should be kept within a specific range. High BP can cause damage to your arteries, leading to heart attacks or strokes. Low BP can cause dizziness or poor blood flow to your tissues. Your pharmacist can tell you what your target should be. You can maintain a healthy blood pressure by eating healthy foods, exercising regularly, decreasing stress, and taking your medications exactly as prescribed. Tags: Untagged
