[|Human|] I have PAD and am on 40mg of Lisinopril a day. I have been taking 1/2 of that some days as my blood pressure has been dropping giving me a quick feeling of faintness and I am tired a lot of the time. My pressure today was 116/66 then within an hour was up to 140/80 then later dropped again. Is this normal?
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that these blood pressure fluctuations are quite normal during the day. They are related to physical or emotional activity. Isolated blood pressure are not conclusive for high blood pressure. I would recommend measuring your blood pressure frequently during the day (in sitting position after 10 minutes of total relax) and write those values in a notebook. You should do this for a week and then show these values to your doctor in order to make the proper changes to your actual therapy. Some blood lab tests may be needed to exclude other possible causes of blood pressure fluctuations: - complete blood count-blood electrolytes for possible imbalance-thyroid hormone levels for possible thyroid dysfunction- inflammation tests (PCR, sedimentation rate). Hope you will find this answer helpful! Kind regards,
