[|Human|] my bp is very erratic; in the morning usually about 131/72 - but now in the evening is is 140/72.  The lower number hardly ever goes above 80.  I am female, age 69, 54 and weight 148.  I am very healthy. Is that prehypertension?  Do I need to take lisinopril?  When I take 1/2 of my husbands lisinopril, my bp goes way down for about a day and a half.  I take no medicine whatsoever.  Thank you
[|AI|]  Hi, dear. I have gone through your question. I can understand your concern.  These fluctuation are common.  Some diurnal variations are also there.  You don't have high blood pressure.  You should go for regular check up and just take some salt restricted diet.  No need to take any antihypertensive medicine right now. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
