    Hello Miriam,


    Blood pressure is affected by many, many different factor.  The fact that you notice changes throughout the day is not uncommon!


    There are several medical reasons why your morning blood pressure might be high than the rest of the day.  First and most importantly, if you take blood pressure medication with a  morning dose, your blood pressure might be high because your last dose starts to "wear off". Or, if it high after you take your medication, note that it takes time (at least 20-30 minutes) for your medication to work.  


    Also, the amount of a hormone in your body called cortisol is highest in the morning, due to your body's normal cycles.  Higher levels of cortisol tend to causes higher blood pressures.


    If your blood pressure remains high in the morning, you should speak to your doctor at your next visit about either increasing/starting a medication or adding a drug taken both in the morning and at night.


    To your health,

    Neil MD

    For at least a month now my morning blood pressure is elevated in the morning, 178/96 and by about 10AM or 11AM it is normal.  I take my blood pressure medicine at about 4AM, an hour before I go to work.  After about 2 hours after taking my medicine I check my blood pressure again and it is still slightly elevated, 158/87.  At about NOON I check it again and it is 125/26.  I take 1 of each in the morning 100MG Toprolol XL, 100MG Cozaar, and 37.25 DYAZIDE Capsule.  DO you think it might be better to take 1/2 of my blood pressure in the evening before bed and the other half in the morning and see if that helps balance my blood pressure morning and afternoon?
