Preop Cardiologist Check Up - High Blood Pressure

soooooo it has now been 13months that i have been going thru the whole "Insurance Approval Adventure". i completed my 6 months of NUT meetings, 1 psych evaluation, call my doctor, call my insurance, call my management group, calling calling asking verifying!! Trying everything in my power to hurry the process along just so i can finally get what ive been waiting for . . . A Surgery Date!! *Stop* Now Breathe! Okay, soo i went to see the cardiologist today for a check up. I have no diseases or illnesses due to my Obesity but my insurance group required that i have clearance from a cardiologist and pulmonologist before they would approve me for surgery . . . This is usually done right before surgery and after you receive your surgery date But my insurance wants it before they will approve my surgery. So i go to the cardiologist today and i had some coffee before i went in and the nurse takes my blood pressure and its 170/ 110!!!!!! WWWOOOOWWW! crazy!! ive never had an abnormal anything. so the cardiologist asks me questions and examines meand runs the ekg and everything is fine. . . i dont show any symptoms of high blood pressure i.e swollen legs, chest pain etc, so i wait for 10 minutes to see if it goes down and during this time, i try to relax and take deep breathes and he checks it again . . . 160/90. Still abnormally high. so the cardiologist says that he wants me to take a blood pressure medication until surgery. He says that i am okay tho. Im super confused/worried because #1 i dont want anything getting in the way of me having my surgery and i dont want to be taking medication. i know that hbp is caused by obesity but ive never had it before. Should i be concern???
