Low Blood Pressure Chart By Age And Height
Low blood pressure, or hypotension, is a medical condition that can occur in people of all ages and heights. It is defined as having a blood pressure reading below 90/60 mmHg. While low blood pressure can be a sign of good health, it can also cause symptoms such as dizziness, fainting, and fatigue. Understanding your blood pressure readings can help you identify when your blood pressure is too low and take steps to manage it.
What is Blood Pressure?
Blood pressure is the force of blood pushing against the walls of your arteries. It is measured in millimeters of mercury (mmHg) and consists of two numbers: systolic (the top number) and diastolic (the bottom number). Systolic pressure measures the force of blood when your heart beats, while diastolic pressure measures the force of blood when your heart is at rest between beats.
What is Considered Low Blood Pressure?
Low blood pressure is defined as having a reading below 90/60 mmHg. However, some people may experience symptoms of low blood pressure even if their reading is within the normal range. This is because everyone's body is different and some people may have a lower baseline blood pressure than others.
