What is the cause of high blood pressure?
Patient: This am my bld preasure was 149 73  66 Some time I awake with high bld preasure  other time 129 55  72,,, I change to normal & high & lows that scare me    I had a 98.45. 72 awhile back    why should there be  such radical changes?  I'm 87  yrs old exercise walking a dog ..sometimes walk at a good clip & slow down wt 125   5'2"  Diabetic controled  5.7 tp 6.4 AC1   What is normal? My cardiologist  thinks it's OK BUT THE READINGS SCARE ME Doctor: If you have long standing diabetic even if well controlled and also age related ,  what happens is your nerves get weak over time what we call autonomic dysfunction,  where there would be fluctuations in the BP.  Till you don't have symptoms don't worry about the fluctuations.  However I would personally prefer your BP on the higher range like between 135-150 and lower 80-90,  secondly don't suddenly change position and things  should be all fine.
