Dizzy when standing up

Lately I have been getting extremely dizzy; tunnel vision; blurry vision when I stand up. It's days I exercise and days I don't. It has been going on for about 3 weeks. If anything, I have been eating a lot of salt lately. Not starving myself. Yesterday I woke up with a headache and it lasted almost all day - and I NEVER get headaches. I drink about 12-15 glasses of water per day. Eat 3-4 times per day. My exercise routine was on hold for a few weeks and I started back, but the dizziness was there even when I wasn't exercising. If your recommendation is to go to the doctor, what would be the illness/ailment they would be looking for?

It sounds like vertigo. It's unrelated to exercising and is just fluid imbalance in the inner ear. I would definitely go to a doctor.

My guess is blood pressure. You need to talk with your Dr. about what is going on. I hope it all turns out fine.

I had a really bad headache and saw spots with tunnel vision on Tuesday. I think mine is due to a hormone imbalance since I am not premenopausal. I've had sinus headaches all my life, but nothing like this before... Could be iron as well... might want to get checked.

I have low blood pressure and this happens to me when it drops SUPER low (which it does kind of often). I would get your bp checked out and see what is going with it.

Also, being anemic can cause some dizziness.

See a doctor immediately. Your body gives you obvious warning signs when something is wrong...don't ignore your body. It could be blood pressure, it could be a balance issue or something worse.

I also have low BP and would say it's blood pressure related, though could also be vertigo or an ear infection as mentioned.

My immediate thing was water or food but it's neither so you should definately go to your Dr to get checked out.

I'm sure it'll soon be sorted.

It's possible that you could be anemic. I have Crohn's disease which causes my body to not be able to absorb iron, which is needed to produce red blood cells. I have to get a blood transfusion ever two years or so to keep these same things from happening to me.

When you stand, your blood pressure drops due to the fact that more blood has to go to the muscles in your legs. This causes blood to be pulled away from your brain. This is not normally a problem, but when you're anemic, you have less blood which causes too much to drain from the upper reaches of your body, thus causing dizziness.

When I start being tired most of the day and dizzy when I stand up, I know it is time to go to the doctor.

If iron deficiency is the problem, don't forget to get a high amount of vitamin C and folate (a B vitamin, also known as folic acid), as these both help the body with the absorption of iron.

This doesn't mean that this is what is happening to you, but it is something to think about. Do you have any health problems? Are you eating enough red meat and dark green vegetables? If not, you may be anemic. If it doesn't clear up soon, you might want to check with your doctor.

But don't let this or anything else posted here freak you out. you may just be exhausted, or anxious, or any of a number of other lesser problems, and getting all worked up over what this might be won't help any. No matter what the problem is, letting it get to you will only make things worse. Stress is one of the worst things that you can do to your body. Believe me, as a sufferer of Crohn's, I know how bad stress can be. I have had 4 surgeries on my GI tract, and the stress caused by worrying about this has caused many more problems that what I would have had without it.

Obviously see your doctor. My guess is similar to others as in BP, however I experienced dizziness one day and when I got to work told someone I wasn't feeling well so fortunately I worked at a nursing home so they check my BP and it had skyrocketed! Everyone was shocked I was standing up walking around and had been all morning So please get yourself checked out

Check your iron levels.

You may not feel hungry but are you eating enough? Are you netting at least 1,200 calories?

Oh, and even if you don't FEEL anxious, it could still be it. I refused to believe it was anxiety at first because I didn't feel anxious/worried about anything at the time.

It could be a lot of things. I'm not a doctor but I stayed in a Holiday Inn Express...

I had the EXACT same symptoms minutes before having a full-on stroke in 2009. Get it checked out. It might be a simple fix but at least you'll know.

Do you use MIO in your water? I loved it the first time I used it and after the second time I was having migraines and vertigo for a week. I thought I was going to pass out a few times too. I drink diet soda and use sweet n low occasionally, have never been sensitive to artifiicial sweetners until I tried that stuff!

Pretty much everyone has said it: vertigo, low or high BP, heart condition. I would go to the doctor and see what's going on. They will probably want to do an orthostatic blood pressure on your (or if you have an at home BP cuff, you can do it yourself) where you take your BP laying down, sitting and standing to note the difference. If it is a heart concern, you will have to wear a Holter monitor in many cases to keep track of your heart's activity. OR it could be completely normal if you stand too quickly. The only way to know is tests!
