Blood Pressure

Blood pressure is a measure of the force exerted by the blood against the walls of the arteries as it flows through them. It consists of two numbers: systolic pressure and diastolic pressure.

  • Systolic pressure is the higher number and represents the pressure in the arteries when the heart beats and pumps blood out.
  • Diastolic pressure is the lower number and represents the pressure in the arteries when the heart is at rest between beats.

Blood pressure is measured in millimeters of mercury (mm Hg) and is typically written as systolic over diastolic, such as 120/80 mm Hg. This is considered a normal blood pressure reading for adults, but optimal blood pressure can vary depending on factors like age and overall health. High blood pressure (hypertension) can strain the heart and blood vessels, increasing the risk of heart disease and stroke, while low blood pressure (hypotension) can cause dizziness and fainting.
