Hypertension is when a person’s force of blood against the artery walls is consistently elevated over a long period of time and causes a constant blood pressure reading above 140/90 mm Hg. When blood pressure is high over long periods of time it can cause permanent long term effects to the blood vessels. You get this reading by measuring how much blood is pumped out of the heart and the overall resistance of the arteries to the flow of blood. You measure the blood pressure by measuring the diastole, which is the heart relaxing and filling with blood, and the systole, which is when the heart is contracting and pumping blood out of the heart. Systolic blood pressure is the top number of the blood pressure reading and the diastolic blood pressure is the bottom number.
Blood pressure has 5 stages of readings; Hypotensive, normal, Prehypertensive, Hypertensive, and Hypertensive crisis. Hypotensive readings are when blood pressure is 90/60 mm Hg or less. A normal blood pressure reading will be around 120/80 mm Hg. Blood pressure from 120/80 mm Hg to about 139/89 mm Hg is considered Prehypertensive. Anything over 140/90 is Hypertensive. Before being classified as Hypotensive, Prehypertensive, or Hypertensive a person’s blood pressure rating must be consistently in the range of each condition. One blood pressure rating will not cause a doctor to classify a patient as Hypotensive or Hypertensive, but…
