my friend who is 16 was taking her blood pressure and it was 220/150. her normal bp is a little high but not that much, somewhere around 133 to 148 over 85 to 95 something. anyways it went from that range to in the 200s and in less than a week. like two days. seriously how could you bp get THAT high in like two days. the reading was right, it wasn't a false one or whatever. anyways if someones bp is that high and they are 16 is that serious enough to where you should call an ambulance or something? or should you just take her to the doctor . i know either way she needs to get checked, but like should you be calling 911 or can it wait cause she has an appt this weekend with her doc. the only thing i know that could of possible rise it THAT much, is she eats a ton of salt, a lot of the time plain, doesn't eat healthy, doesn't exercise, and is under a ton of stress. could that raise it that much in such a short time? also she s underweight , real skinny with that high bp ?
