If my bp is around 125/87 and goes up to 165/108 when i sit or stand should i be on bp meds??? my pcp says just lose weight. i think i have hyper pots?

Do not understand what u mean by around 125-is this at home? Many have Higher BP in office. You did not say how tall you were or if, when they took the standing BP, they let your arm hang straight down. So for every inch you cuff is below heart level when standing BP will be higher by 2 mm Hg. So if your cuff is below heart level in BP will read 20 mm Hg higher. Na more important than weight.
