[|Human|] I have been having problems with high blood pressure for a while now.  My doctor put me on a low dose diuretic which has lowered it a few points.  My issue is that the longer I sit the higher my blood pressure goes.  Once I get up and moving around or lay down it seems to bring my blood pressure back down.  I am a computer programmer and I sit all day writing code.  Could I somehow be effecting renin excretion by sitting?  Or something else?  I also have sinus tachycardia my resting heart rate averages at about 110.
[|AI|]  Hello! Welcome to Chat Doctor! I carefully read your question and would explain that your symptoms could be related to orthostatic hypotension. You should know that blood pressure raises during standing up from sitting position. If there is a decrease in blood pressure more than 20 mm Hg during standing up position compared to sitting position, orthostatic hypotension could be the cause. A head up tilt tests is needed to confirm/rule out this disorder. Hope to have been helpful! Kind regards,
