This is my first post here, and I am happy to have found such a great resource.
Lately, I have found that when I stand up quickly my eyes start to black out and I feel as though I'm going to pass out. This is weird to me, as I definitely feel as though I've been eating enough calories! I'm eating at least 1200 a day, usually much more (1500+). It especially happens to me right after exercise (ie walking up a big hill, cardio machines, etc).
Has anyone had experience with this feeling as well? Do you think it could be due to too big of a caloric deficit? or perhaps I'm not hydrated enough? Something else?
I haven't passed out, it just feels like it. Usually if I try and breathe faster during an episode the feeling goes away faster.
