Detailed explanation-1: -High blood pressure, also called hypertension, is blood pressure that is higher than normal. Your blood pressure changes throughout the day based on your activities. Having blood pressure measures consistently above normal may result in a diagnosis of high blood pressure (or hypertension).

Detailed explanation-2: -This is called diastolic pressure. Your blood pressure reading uses these two numbers. Usually the systolic number comes before or above the diastolic number. For example, 120/80 means a systolic of 120 and a diastolic of 80.

Detailed explanation-3: -Use 120 over 80, which is written as 120/80 mm Hg (millimeters of mercury), as an example. The “120” is the top number and is known as systolic blood pressure. It represents the pressure in your arteries when your heart beats. The “80” is the bottom number and is known as diastolic blood pressure.

Detailed explanation-4: -Normal: Less than 120/80. Elevated: Systolic between 120-129 and diastolic less than 80. High blood pressure (hypertension) Stage 1: Systolic between 130-139 or diastolic between 80-89. High blood pressure Stage 2: Systolic 140 or higher or diastolic 90 or higher.
