Increased BP on sitting

[aroman01]

i get dehydrated easy and notice it affects my bp. this week though, although my bp is normal when laying down (118/78) when I take it sitting, it has been around 140/102.  It gets this high when I have been sitting at the computer for more than 1/2 hour, otherwise it stays within the normal range as far as I know. I normally have normal to low BP. The 102 is making me a bit nervous!  any ideas?

here's a bp tracker that may help keep track of what's going on http://www.medhelp.org/user_journals/show/284965/Blood-Pressure

I thought of the same thing with Postural hypotension I've had OH/OI for many years (36+) along with other ANS (autonomic nervous system) issues - my bp can be 70/40 with meds but normal is 90/60 and sometimes will raise to 240/120 due to my Autonomic Dysfunction issues.

Dr's wanted to treat me with meds for the raises but I said no way and after a bit it finally went back down to my "normal"

Hello and hope you are doing well.

The nervousness could be causing the high blood pressure. There is an entity called postural hypotension, a condition in which the peripheral arteries dilate, leading to pooling of blood in the peripheries. This in effect causes decreased circulation of blood resulting in dizziness/lightheadedness. This is more pronounced if the person stands up from a lying down position. This is detected by recording the blood pressure recordings in the sitting, standing and lying down positions. If the variations in blood pressure recordings are more than 10 mmHg, it is diagnosed as postural hypotension/Orthostatic Hypotension. Check with your doctor to rule out this condition.

Hope this helped and do keep us posted.
