hi doctor, i have been experiencing the following symptoms lightheaded, dizziness, nauseous, flushed. one 2 occasions my co-worker even told asked me if i was OK. She said i looked pale as if i was going to pass out. She got me a glass of cold water but the minute i sipped i had to run to the bathroom to throw up. I have been having these episodes for a quite a while now. they come and go. I have had blood work done and everything is normal. at one point i was told i was borderline diabetic. to just control what i eat. I do have a family history of diabetes and hypertension.
