Hi everyone, since coming out of the hospital I have noticed my blood pressure change from the 120's to below 100. I wouldn't be that concerned normally, but some of my readings are going lower then they have ever been. I am getting light headed a fair bit even with just sitting quietly, when Is the blood pressure to low and something to worry about. The readings I am getting are:- BP-98/64 HR 60, BP-95/59 71, BP-85/54 HR 61, BP-89/47 63. so is this anything to be concerned about, thanks Liz.
