Hi, lately I have had multiple problems. I get headaches with vision spots, which I thought would turn into a full blown migraine, but doesn t. I will randomly get super crazy hunger pains that make me sick and irritated. Over the past few days, often times shortly after I eat, I ll get really shaky, nauseous and have a pounding heart. I ve lost about 6-7 pounds in 4 days. I don t have a family history of diabetes, could it still be possible that I m diabetic?
