The sbp is the pressure that is generated when the heart squeezes. Dbp occurs when the heart relaxes. 120/70 is considered normal in adults. Less than 100/60 (of either number) can ...Read more

What are the risks of low blood pressure?

What are the risks of low blood pressure?

Congratulations: In the absence of symptoms (dizziness, faintness, etc.), naturally occurring low blood pressure is not a clinical problem. Indeed, low pressure is a marker of longevity in my practice. The problem is if there's another not-natural cause for low bp, e.g., illness, medication side effect or drug interaction, occult blood loss. Then looking for root cause and remedying that is the answer! ...Read more

There are limits: i've never seen a healthy adult with a BP of <80 systolic (top number). ...Read more
