I been having different symptoms but when ever I get hungry everytime and don't eat right away I start to feel sick, nauses, stomach hurts start to feel light headness. I had blood work done at hospital and thyroid test, it came back fine hospital said. And every time I don't eat on time I have to lay down cause my stomach hurts and lightheadness occurs. 2years ago I had episode of nauses,lightheadness, I had to sit down on floor my vision started to blur and sounded like people were talking slow around me, felt like I almost fainted and i was weak, fills like I couldn't talk or breathe right either. And not to long ago I was standing again and started to feel nauses, vision started to blur had to sit felt very weak. Does anybody know what maybe wrong with me?
