Diagnose me please...

Get a wheel chair so you never have to stand again

It might be postural hypotension - blood pressure drops as you stand up. This can happen if you have cut your sodium intake too much. It could also be low blood sugar if you are not eating enough or leaving too long between meals.

You may have fluid in your ears. I've had that same problem and when I went to the doctor that's what they found. Good luck!!

i usually have the same problem, but i have a serious eating disorder ..so i guess it's different for u...maybe u overwork urself?

I have the same thing....but I know for a fact I also have low iron levels. Maybe you should get your iron levels checked out? My dad (even at 30, he's still the smartest guy i know!) says it could be low blood sugar too though.

Your diary is private, so I can't see if it's the types of food you are eating, but it can be anything from anemia, low blood pressure (just because you've never had it doesn't mean you don't now), vitamin deficiency, vertigo, or a host of other issues...can't tell you for sure with little information.

Typically dizziness like that is due to low blood pressure or something called orthostatic hypotension where your BP drops when you stand up causing dizziness or the possibility of fainting.

Might be a blood pressure change, happens to me sometime, no biggy. Just stand a little slower and drink more water, 8 - 8oz glasses is the minimum, if you're not working out.

My official diagnosis is...

1. Allergies/sinus issues
2. Pregnancy
3. Dehydration (6 glasses may not be enough, especially if you're exercising)
4. Diabetes
5. Hypoglycemia
6. Hypothyroid
7. Hyperthyroid
8. Brain Tumor
9. Inner Ear Problems
10. Multiple Sclerosis
11. Not enough calories
12. Too much sugar in your diet, not enough protein
13. Heart defect

Some people just get dizzy on standing. It has to do with fluctuations in your blood pressure. Go see your doctor! Seriously.

That happens to me all the time... I call them head rushes. It stops me in my tracks. I tend to have low blood pressure. Doctors say it is not to low though. That's what I think it is. When I eat healthy it happens more.

and please don't tell me to go to the doctor. Just looking for someone who may have a similar problem.

I get dizzy when I stand up. Nealy every time I stand up, the room spins a bit and then my eyes refocus and I'm fine. I drink water - not as much as I should, but about 6 glasses per day on average. So, I don't think I'm dehydrated. I've never had Blood Pressure problems, either high or low. I eat enough. Work out a lot. Any ideas out there in MFP land?

i have that EXACT problem..maybe it is dehydration, i don't drink as much as i shold either..mine is like i get 3 second blackouts..kinda scary, never had it as much in the rest of my life as i have recently..good luck

They used to tell me it's lack of Calcium. Try some multi-vitamins. Also make sure you are hydrated. It is cause by a sudden drop in blood pressure when you get up.

This is a pretty good article about it:

You're gonna hate me but... you should go to the doctor. Seriously, if its happening every time you stand up thats not good.

Best guesses on my part (DISCLAIMER: I AM NOT A DOCTOR):
(1) Vertigo. Inner ear issues can come out of nowhere.
(2) But, sounds more like a blood pressure thing to me. This could be a result of being dehydrated. When you go stand up it can change your blood volume and push more fluids into the intracellular spaces of the tissues. Therefore, if you're alread dehydrated then you're decreasing an already low blood volume even more, thus dropping the blood pressure. OR, could just plain low blood pressure. If you've been dieting pretty strictly you may have altered your salt intake which can alter your blood pressure. Anything to do with kidneys can alter blood pressure. A kidney infection will usually drop blood pressure like a rock.

NONE of these things are good and some are straight up serious. You should see a doctor to make sure your blood pressure is ok. Just because its always been ok in the past doesn't mean its ok now.

I get dizzy and get headaches if I am hungry, thirsty, tired, stressed.... It could be any number of things really. I know you don't want to hear "go to a doctor" but that's the only way you will find out for sure. If messing with your lifestyle (diet, sleep, stress) doesn't help then I would say go to a professional if you keep experiencing symptoms.

Hypoglycemia is a possibility too... but honestly most hypoglycemic episodes will make you feel dizzy sitting or standing and won't go away after a minute unless you eat/drink something with sugar in it.
