What causes fluctuating BP throughout the day?
Patient: I'm 56 yr old female weighing 240 & have started eating healthly & do light water aerobics & indoor short power walks.  My b/p has never been really bad, but doc put me on 10 mg of Lisenipril because it was sometimes elevated. For the last few days, I have woke up a little dizzy when taking b/p it is running 116/77,108/65,115/66, 107/69 this is check all thru the day. Yesterday I just took 1/2 Lis. and it still was lower than normal.? Doctor: your blood pressure readings are in normal range.  so it is unlikely  it has caused for diziness. diziness may be due to sudden drop in blood pressure when you stand from from bed in early morning which is called postural hypotension. so dont stand at once from bed. change your posture gradually from supine to standding. check  blood presssure regularly from your family physician. get his advice regarding lisprinol dose according to blood presssure monitering results.
