Getting light headed and dizzy?

For the last three days whenever I stand up I get very light headed and dizzy, I have never had this problem before. Is this anything I should be concerned about? I have been eating around 400 - 500 calories a day and have been getting my required protein each day and have been drinking at least 48 oz of fluid a day. it has been so bad at times that I have had to sit back down because the room was spinning.

Are you on any blood pressure medication?  I had similar feeling but it was due to my blood pressure medication.  I no longer needed it, my BP was normal.

Yep, that's totally normal. You're eating like 1/8th the amount you're used to and your body is trying to get used to it. Call your surgeon if you're concerned.

It is fairly common - often because of the blood pressure meds no longer being needed - but IF I remember correctly, you weren't on that.   I'm curious - does your surgeon's post-op diet call for 48 oz of fluid?  Most say 64, I'm wondering if you shouldn't try to increase that?  Definitely worth a call to your doc, just to touch base and see what he says.

And stand up a little more slowly.  As we're dropping weight, our center of gravity shifts, and sometimes THAT can make us a bit wobbly - our brain is used to one center, our body is recognizing another, and they don't always mesh...

Hope you can make it to MG on Saturday, Tim !  Have a happy Thanksgiving! 

At 18 months out I still have that happen when I stand too quickly or have been lying down for awhile. Our body was used to having to work harder to push the blood around and now, even with a little bit of weight loss and that can affect it. Another thing that happens with this surgery is it can mess with your blood sugar levels. I know that I have this problem now. If it continues or worsens, call your doc. You can see if it is a blood pressure thing by getting that checked at a Walmart or Kmart pharmacy or whatnot.Good luck.

I notice this happens to me if I am not getting enough water in for the day.  also could be blood sugar related - as you are eating less and less carbs and sugar.  I am almost 9 mos out and it still happens to me occasionally.
