So it started half a year ago, my body has been feeling weird. I just need to eat every few hours, when I say eat I mean I actually need to have a full meal , snack won't help. If I don't eat for long, I would feel very weak and feel like imma going to faint. I make sure I eat every 3-4 hours. But the funny thing is once I had my dinner, usually around 5-6, my body would feel normal again and won't have to eat until morning breakfast. Before I could wait at least 5-6 hours before meal or even longer, now I just need to eat every 3-4. And evmerytime I feel sick or feel like faint I would drink sth sweet like oj. I'd been to so many doctors, all blood tests are normal. I even tried to prick my finger to see if I'm low sugar, it turned out normal again. Endoronlogist thinks I just need to eat more often that's it. I've already gain 20lb because of this. I can't get a diagnosis. Any body ???
