My aunt has high blood pressure and has to go to the doctors. But no one will tell me what it means.
So I'm getting worried.
Does anyone know what it means? :( :(

Here you go...

What is High Blood Pressure?

And in the US my guess is perhaps 30 or more percent of the adults have it. For most it is a matter of diet (foods we eat) and our weight.
But it is normally easy to control with medication

From the AMA (American Heart Association) 1 out of 4 adults has it.
