Re: OT: Swimming and blood pressure. WAS: Big stress test!!

Been dancing a bit too much, Notan? Guess you got the bragging rights on that

one.

One can measure postural hypotension: take BP lying down, then stand up, and

watch it plummet. But I suspect you are right: it could likely be increased by

dehydration. He was pretty athletic at the time, with a pulse rate, resting, of

under fifty. But not tall, then or now.

Good luck with the surgery next week!

He had been growing lots lately and is now over 6 foot. His blood pressure

dropped about 20 when he went from laying down to sitting. My husband has high

blood pressure and I have low too, so we are planning to get oursleves a machine

to check at home. Hubby's doctor has been telling him to get one for years. I

think now is the time.

Notan, hope your foot gets fixed again soon, thanks for the info.

My wife would have loved that, but no. Back a couple of months ago when

I was still wearing those protective boots I got up and danced (more

like some kind of deadhead swaying kind of thing) to a few songs on a

CD. Boy, did I pay for that. I still walk slow and awkwardly. Today has

been relatively good though. I probably look almost normal walking

today. Just slow. Next week is back in the boot. At least I don't have

to go back to wheels.

Right. I didn't mean to get into that. I just wanted to point out that

with or without such a condition the pool is a more likely place to

experience a problem of this type than many things we do.

BTW: Some people who have bad cases of this kind of thing (Orthostatic

intolerance - OI) buy G-suits. Unbelievable, but I suppose if it would

help achalasia, not that it would, many here would be quick to get one

too. Check this out:

Oh, yikes, Notan, read the OI board. And feel really blessed to have gotten

away with just Achalasia. . . . About the same as I feel when I get deeply into

the natural tube feeding sites.

Long time ago, I broke the middle toe on my right foot (heard it beak: a really

awful " thwock " sound). But I was having company, so went grocery shopping,

cooked dinner, entertained, and THEN went to ER. They Xrayed and taped it.

Week later, still in awful pain, a friend gave me the name of her orthopedic

surgeon. He taped the leg from toes to knee, and I got a wooden boot. Redid

the Xrays once a month for four months, during which I wore out one of the

wooden boots each month. It would not heal, so ended up with surgery so he

could see/fix whatever was keeping it from healing. Turned out in the pre-ER

period, I'd worked flesh in between the ends of the broken bone, and they

couldn't reach each other to begin to heal. The pin for the procedure, after

he'd cleaned up the mess I'd made, was run up the length of the toe and came out

the end of the toe, and had a rubber bottle stopper on the end. And I wore out

another shoe in the next month. Then a repeat Xray, healed, and they pulled out

the wire, applied an antibiotic to the exit wound, and I was good to go. Never

quite decided which was the bigger relief: getting rid of the boot, or getting

rid of the damned tape! Something to be said for excellent surgeons: In the

twenty-five years since, I've never had one twinge, nor ache, nor twitch.

Get well, friend, I'm sure you'll dance again (one way or another!).

I not going to dig up the science on this but, from what I heard, there

are reasons this happens to swimmers. One is that it is more likely to

happen when a person is dehydrated. Swimming and playing hard in water

can produce a lot of sweat, which you don't notice because of the pool

water. I have heard that competitive swimmers can loose pounds of sweat

at an event. Be careful at hot tubes too! Ever notice that you need to

pee more if you have been swimming? It may be true, because if the water

is cold it will cause the blood vessels near the skin to contract, (to

keep heat in the core of the body), which increases blood pressure

causing the body to compensate by releasing water through the kidneys.

That also adds to the dehydration. When going from horizontal to upright

blood with the body fluid moves down, due to gravity, toward and into

the legs this can cause a loss of blood from the brain. If you are

dehydrated there may not be enough body fluid to keep the blood pressure

in the brain high enough. The taller a person is the more likely this

is a problem. My son, who is 6'4 " , has fallen a number of times at the

gym (not alway at the gym's pool) because he forgets to keep hydrated

and works out for long periods. Another thing that happens at the pool

is that when in the water it puts pressure on the body, much like a

pressure suit a pilot would wear to maintain blood pressure in the brain

while fighting strong accelerations. When the pressure is released it

wants to return more blood to the limbs which can also mean less for the

brain when getting out of a pool. Problems in the pool may not be a

problem if wearing long compression socks, but who wants to do that?

BTW: I was supposed to have surgery today to remove a broken screw from

my foot and another that will probably break. They were used to hold a

joint in the foot together. I didn't even know anything was wrong. They

found them on a follow-up X-ray. I thought these things were titanium

and made to last forever. Maybe the screws are just surgical steal. In

any case I think there should be some bragging rights here for being

able to break screws with just the bones in my foot. The surgery has

been put off until next week.
