Low Blood Pressure (Hypotension)

Key Points

Overview

Low blood pressure, medically known as hypotension, occurs when your blood pressure reading is consistently less than 90/60mmHg. For many people, this is their normal healthy state and causes no problems or symptoms. However, for others, low blood pressure can lead to symptoms like lightheadedness or fainting. This can happen if your body isn't getting enough blood flow to vital organs. If symptoms appear, especially when standing up quickly, it may indicate a specific type called postural hypotension. Management typically involves lifestyle adjustments and addressing any underlying causes, as medication is rarely needed. Regular checks are important to understand your normal blood pressure and identify any issues.
