PATHOLOGY

Detailed explanation-1: -As a general guide, the ideal blood pressure for a young, healthy adult is between 90/60 and 120/80. If you have a reading of 140/90, or more, you have high blood pressure (hypertension). This puts you at greater risk of serious health conditions, such as strokes or heart attacks.

Detailed explanation-2: -For a young, healthy adult, normal blood pressure is about 110/70, but generally, the lower your blood pressure is, the better. If you have a reading of 140/90 or more, you have high blood pressure, also known as hypertension.

Detailed explanation-3: -A sudden fall in blood pressure can be dangerous. A change of just 20 mm Hg-a drop from 110 mm Hg systolic to 90 mm Hg systolic, for example-can cause dizziness and fainting. And big drops, such as those caused by uncontrolled bleeding, severe infections or allergic reactions, can be life-threatening.
