Topic: OT - Blood Pressure And Caffine (9 msgs / 203 lines)
1) From: Larry Williams
Have any of you determined the extent of influence of caffeine on blood 
pressure.  How long after you drink coffee does the caffeine effect the 
BP level.  It seems that I have read where it raises BP for a short 
period after drinking coffee.

2) From: Robert Joslin
1.  In habitual users, little or no change
2.  After period of abstension, caffeine may raise blood pressure. Then
tolerance develoops with multiple exposure and BP returns to baseline level.
3.  STRESS plus acute dosing of caffeine causes small increases in blood
pressure in caffeine naive individuals.
4.  In a meta analysis of 11 controlled clinical trials in which the effects
of long-term coffee drinking on blood pressure was assessed, a small
increase of 2.4 and 1.2 mm Hg were found, respectively, for systolic and
diastolic pressure.  "Compared to other factors known to affect blood
pressure on a daily basis, the clinical significance of the increases, if
any, resulting from caffeine ingestion has been considered to be minimal..."

I normally run about 100-110 over 50 - 65 BP...resting pulse rate around
50... I am in really good shape, PT 5-6 days a week, hour and half a day,
and I do this all the time.
Went to sick call today (getting dizzy standing up - like ALL the
time...anyway), I had just finished the end of my thermos - 137 over 75.
Corpsman commented on it since I was there yesterday and was much lower
yesterday.
The Doc had me do BP lying down and then sitting up - (yeah got dizzy), no
effect to my BP 30 from the standing - but 30 min after my last coffee...I
had dropped to 120 over 65 already.
So I can attest that there is a coffee effect - not sure about the caffeine
since I don't drink caffeine, I drink coffee...
Doc wants me to see the neurologist...yikes.

Normally my blood pressure is 120/80, but a couple of months ago I had to go
see the doctor for a checkup and was drinking a cup on the way there. When
he took my blood pressure it was 140/?. He asked if I had been under a lot
of stress lately, I told him no, but I just finished a cup of coffee. He
said that was the reason.

Hmmm, something else the amorphous mob of hand wringers had wrong.

Just having the doctor take your BP can cause it to rise--you are so  
nervous about it being too high (and perhaps getting criticized) that  
it's a self-fulfilling prophecy. It's called "White Coat  
hypertension."  Often, the measurements you take yourself, or at the  
machine at the drugstore, are more accurate because there's no  
emotional overlay. Of course, caffeine is a stimulant......

"...that was the reason."
No, no- it's nearly mid-point between the Vernal equinox and the full moon.
We pay 'em to practice.
I'm glad to have the Claret circulating regardless of whatever restriction
may be present that causes back pressure in the flow.
I had taken Sarah's foster Min Pin (Brad) for his morning constitutional.
Egad- for such a little mutt, he pulls like a John Deere. After he refloated
Titanic and other necessities, I gathered things in a trick or treat bag
that I donated to a park trash can.
Back to Cafe' Mexico for a nice hot burrito and a mild one for Karen, who's
still putting things together from the move- 5br home>>>1br apartment!
Dyslexia might have been grim earlier, but the burrito sure cleared my
head...
With unusual restraint, I had roasted a Fresh Roast batch of  Ethiopian
Sidamo to City. Got all of First, then quit at 13:40. After 24 hours' rest,
a wonderful double debuted from the Capresso. Espresso brew on a City roast?
Yup!
Cheers, Mabuhay -RayO, aka Opa!

8) From: Michael Wascher
Sean,
It sounds like something Jean went through a couple years ago. She had
dizziness and also had frequent changes to her vision. It turned out to be
an easy fix -- she takes dostinex to shrink a tumor in her pituitary gland &
gets checked once a year.
Sounds bad, but it turns out that the majority of people have these. For a
few a tumor impinges on a nerve and causes vision changes, reduced
peripheral vision, dizziness, migraines.
Best of luck to you. And don't worry -- it's bad for the blood pressure.

will pass that to the Doc - I hate not knowing what may be wrong...  Takes
an act of congress to get me to sick call, so this is all new to me!
