\\\\I am 29, 5 ft 10 and I weight 17 st (238 Pounds). Do you think with excercise and diet, I will be able to get my bp down to normal levels or will i be put on meds for the rest of my life? \\\
Maybe......maybe not.
You are young to have hypertension and if this is confirmed by a 24 hour BP monitoring, then it will need investigation and treatment.
Certainly the measures mentioned above by the post of Buenchico will be helpful but you will need tablets to bring your BP down......tablets for life.
However, if the hypertension is not seen to be a permanent feature on 24 hour monitoring, then treating your anxiety and stress with perhaps beta blockers as well as the life style change that has been mentioned, may all that may be necessary.
Keep us informed.
