Dizzy when I stand up

[Lefti 21]

When I stand up, I feel a bit dizzy. Not like pass out dizzy, just like it gets a bit dark. It sounds terrible when I say that. Anyone else having that experience?

I was getting dizzy when I stood up and I finally worked it down to not getting enough calories. I upped my calories about 100-200 a day and the dizziness has been significantly reduced. Still happens every once in a while, but I find that it happens when I haven’t eaten in a while.

Low blood pressure. Specifically orthostatic low blood pressure. Your BP is low so when you stand your blood goes to your feet (gravity) & it takes a bit longer to get back up to your head hence feeling dizzy & your vision narrowing or disappearing briefly. I experience it several times a day. Get up slowly. Wait a short time when you stand before you start to move. Wriggle your feet or walk on the spot to get the blood moving. I usually reach for the wall, some furniture even a person just to ground me for the time my vision disappears. I sometimes feel nauseous at the same time. Low caloric intake/low or drops in your sugar levels can make it worse.

For most this condition improves or disappears after a few months. I still have it because I always had a tendency towards low BP - it just happens every day now versus a couple of times a month before surgery. But that’s me.

Check with your medical team though to make sure.

it's common after surgery - I had it at first but I haven't felt it in a long time (I'm over six years out). It's due to low blood pressure. Just get up slowly. Here's info about it (and most of us have the acute version - it'll usually resolve itself over time):

Wow, yeah. Just took my bp and it was 116/66

Also, make sure you’re taking in enough fluids.

I experienced that for the first few months up until I started getting in at least 700 calories per day. I noticed if I ate less than that, I would start to feel dizzy again. I’m sure that would be different for each person but that was the magic number for me.

I have experienced this too and my blood pressure at the dr was pretty low. He said it was still within the acceptable range right then but to keep an eye on it. Since I am able to eat more now (at five months out) this has gone away completely for me.for what it’s worth the dr seemed to attribute it more to likely dehydration than low calories though. He said to make sure I am getting enough to drink so I guess that can also be a cause.

Don't think its dizziness I think your getting lightheaded. I got that alot and only passed out 2 times. Saw a doctor and he said it would pass wich it did and now only occurs once in a blue moon. Noticed it happened alot when I sat in my recliner Nd was pulling myself up with the arms of the chair. Think its the sudden bp change.

UPDATE: My doctor said that my BP is perfect, and most likely he said this feeling was my body responding to a lower blood volume due to weight loss. He also said to make sure that I reach my Water goals (which I do).
