High Blood Pressure
High blood pressure, also known as hypertension, is a “silent” disease that occurs when your blood pressure is consistently high. Normally, stage 1 hypertension is between 130 and 139 systolic mmHg or between 80 and 89 diastolic mmHg. Stage 2 high blood pressure is above 140/90 mmHg. It would be considered a hypertensive crisis if the systolic pressure is high than 180 mmHg and/or the diastolic pressure is high than 120 mmHg.
With no obvious symptoms, people could hardly recognize them, leading to life-threatening health problems, such as congestive heart failure, heart attacks, stroke, and kidney disease. When the flow of blood pressure rises in the artery to the brain, the walls of the artery become narrow and stiff. The increased pressure may cause the vessels to rupture and bleed, which triggers hemorrhagic stroke. High blood pressure may also cause clots to form, which may cluster and block the movement of blood, leading to an ischemic stroke. [7]
