Hi there It s a pleasure to help you out, it s good you understand the gravity of the situation . Treatment of High Blood pressure starts with Life style modifications first and on the second stage with meds if life style changes doesn t proove to be sufficient Lifestyle Modification consists daily vigorous morning walk 45 Min a day 5 times a week, low salt diet, smoking ceasation, avoidance of junk food, fruits and fiber rich diet I will advise you to start following this schedule strictly for a period of one month and then monitor your BP after one month . Hopefully it will lower down your blood pressure and help your body get used To physical activity and slowly u will not feel breathless and if it doesn t then we need to add anti hypertensive meds along with lifestyle changes .
