High blood pressure is a condition in which the long-term force of the blood against the artery walls is high enough which may eventually cause health problems, such as heart disease. A blood pressure reading is given in millimeters of mercury.
- Heart attack/stroke: High blood pressure can cause thickening of the arteries, which lead to a heart attack, stroke or other complications.
- Heart failure: To pump blood against the higher pressure in the vessels, the heart has to work harder, which causes the walls of the heart’s pumping chamber to thicken (left ventricular hypertrophy). Eventually, the thickened muscles have a hard time pumping enough blood to meet the body’s needs, which lead to heart failure.
- Kidney dysfunction: Weakened and narrowed blood vessels in kidneys prevent organs from functioning normally.
- Loss of vision: Thickened, narrowed or torn blood vessels in the eyes result in vision loss.
- Trouble with memory or understanding: Uncontrolled high blood pressure affects ability to think, remember and learn. People with high blood pressure has trouble with memory or understanding concepts.
