Low Blood Pressure - Introduction
Definition:Hypotension is the medical term for low blood pressure , generally considered to be a systolic blood pressure of 90 mm Hg or less in an adult. Low blood pressure is an abnormal condition where a person's blood pressure (the pressure of the blood against the walls of the blood vessels during and after each beat of the heart) is much lower than usual, which can cause symptoms such as dizziness or lightheadedness. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidney; the organs do not function normally and may be permanently damaged. Low blood pressure is defined primarily by signs and symptoms of low blood flow. In fact, some individuals may have a blood pressure of 90/50 and have no signs or symptoms of low blood pressure, and, therefore, not have low blood pressure while others who normally have a blood pressure of 130/80 may develop symptoms and signs of low blood pressure if their blood pressure drops to 100/60.
