I am 54 yrs, 5'4". I am taking three medications: Atenolol, Norvasc and Hydrochlorothiazide. In january 2011 I had medical insurance, always had blood pressure readings of 183/90 with pulse at 45. Now I don't have medical insurance, went on a protein diet went from 205 lbs. (January 2011) to 170 (May 2011). Now my blood pressure usually is 116/65, pulse at 48. Only when I exercise on the treadmill does my pulse go up to 65 (exercise every day for 30 minutes). Should i still be taking all three medications even though my blood pressure is now low?
