What is the average diastolic pressure in an adult, measured in mm of Hg?

The average diastolic pressure in a healthy adult typically ranges from 60 to 90 mm Hg. Diastolic pressure is the pressure in the arteries when the heart rests between beats, and it is an essential component of blood pressure readings, represented as the lower number in a blood pressure measurement (systolic over diastolic).

A diastolic pressure below 60 mm Hg may be considered low, potentially leading to symptoms like dizziness or fatigue, while pressures above 90 mm Hg may indicate hypertension and increased cardiovascular risk. The range provided in the correct option reflects the normal physiological parameters established by health guidelines and research.

Other ranges provided do not align with these standard measurements of diastolic pressure.
