Dizzy after standing up.

[peanut]

It takes a surprisingly long time for the body to fabricate more blood.

spare blood is held in the liver and capillaries and lymphatic system . The body can find reserves in seconds when needed.
Heres an interesting explanation of dizzyiness on standing

Another aspect of cyclists' legs is that the blood vessels are also larger than in the standard population. When a cyclist is relaxed the blood vessels dilate and can hold a large quantity of blood which when you stand up isn't available for the brain and will take a while to get squeezed and pumped up above the heart.

from the article in the link it is suggesting that the blood can't rise to the head as fast as you can stand up. If you stand up slowly it suggests that you might not get the dizzy spell

I went to the Doctors,

I said, "All I can see is Donald Duck in one eye, and Mickey Mouse in the other"...

The doctor said "Your having Disney spells".

Just like that, Just like that...

Hello all

I've had a stack of precautionary tests, MRI, ECG, EEG, echo, heart trace, brain something, all clear and normal other than a large chamber and some slight irregularity in my heart beat, nothing to worry about it seems although I'm back in for some follow ups with cardiology to be sure

The nurse doing the heart thing asked me if I was an athlete which amused me at the time, and today the nurse checking my blood pressure took my heart rate again manually, 37bpm for more or less resting, I had no idea it went that low for resting, thought it was about 70, google tells me 40 is the low limit for resting rate

I tried to get the doctor interested in it as a cause for being dizzy and also for feeling sleepy and nodding off at work, he didn't seem interested

it can't be right can it? yeah 10 hours a week of quickish cycling to work but Big Mig I most certainly ain't, I'm 43 and in reasonable but not special nick

I guess I'll get another bite at the cherry with Cardiology, I've had my BP checked from time to time in the last decade and no-one's ever mentioned this before

I had similar dizzy spells a while back, I'm 5'10".

I would get dizzy if I had been crouched down for a while working or looking at stuff in shops on the bottom shelf. When I stood up I would feel faint and see stars and become dizzy.
GP checked heart rate and blood pressure and all was fine. He told me to just get up a little slower and it worked.

Now when I have been crouched down I get up in two stages, legs straighten but back bent over so that my head is still low down and hands on knees and then stand upright. A bit like unrolling into an upright position. It isn't particularly slow, just taking a second or two to get from crouched to upright with a bit of a pause in the middle.

my heart rate sitting down working at a computer is indeed anywhere between 36 and 40 bpm, and not awfully regular, google suggests that makes me a case to see the doctor asap, given if I've just be given as good as an all clear from a specialist after tests, I'm not sure what to think, that can't be a normal reading surely

as for getting up suddenly, I'm doing that already and yes it works

Wow i wish i could have a resting hr like that,the lowest i got was low fourties but that was a few years ago.Your heart and cardio is very fit by the sounds of it,and miguel indurain had a low of mid twenties didnt he at some point in his career?Coincedentally my wife is suffering with dizzy spells at the mo,it seems to be an inner ear thing,or possibly a touch of vertigo.
The nodding off could be just a case of being tired ,are you working long hours ect?i hope you find out,but if the doc didnt seemed concerned before,hopefully thats all it might be?

Ah but how much is it when you are awake ??

glad to see you're still around mate. Thought we'd lost ya

I have the same problem so I have to stand slowly and not look up at stuff above me etc
Last time I went to have some blood tests it came out like Heinz ketchup I kid you not. I thought it was going to solidify

Col that is likely to be a virus which has infected the fluid in the inner ear.
I had it twice last Christmas . You wake up with the room spinning like you're drunk and you can't make it stop. If you stand up you nearly fall over . Its horrible.
Funnily enough the room doesn't spin completly just 90 degrees or so repeatedly .
At night time you get some tinnitus which can be annoying like a car horn in the distance
It tends to reduce throughout the day but comes back over night. Took about 6-7 days to go from memory.

I think you hit the nail on the head there,she has had it for five days now and its worse if she looks up,but she hasnt mentioned tinnitus as she has perforated eardrums and this is the first problem she has had in 20 years since they hoovered them out.She has called saying the doc is leaving a prescription for her,im off to get it now.

 

[Tynan]

been busy, still busy, new job etc etc

I don't think I've done anything to deserve a heart rate like that, I do about 100-120 miles a week commuting at a top speed of low 20s and I've put on over a stone since last summer (hols, injury enforced break and crimbo)

I'd love it if was a sign of excercise, maybe the nodding off is tiredness although I nearly never feel like I get enough sleep if that's what it is

ah well, see what the cardio types say I guess

still, all those tests have made her indoors happy

(her indoors is a barrister making three to four times what I do btw)

unfortunately there is nothing you can take to treat a virus. It just has to run its course. Antibiotics only work on abcteriological infections.You can get some anti nausea tablets though which would be worthwhile

It seems there is a start of an infection with water getting in,so going on her history its to hopefully stop anything becoming fully blown,as she used to suffer badly years ago,fingers crossed its nipped in the bud.Sickness has not been an issue luckily,but the dizzyness has been bad,with a slight ache strangely in the less infected ear according to the doc.
