Weird Blood Pressure

I hava a blood pressure of 100/91.  The systolic is low and the diastolic is high but I can't find any information as to what this means.  I am only 20  years old and female with no health problems.  What does this mean?

Hi brilliant!  Welcome to the Heart Forums

Were you using one of those BP monitors in a store?  Those can be inaccurate.  Have your had your BP checked by your own physician?  Sometimes, you can call your doctor's office and talk with the nurse to see if they'll check your BP (without an actual appointment).

Let us now what you find out.
