I'm 17 and I get spells of very low blood sugar. I get very close to passing out regularly, but I've usually been able to prevent it by laying down and getting some fresh air. I vomit a lot because of this. It's not that I haven't eaten in all that long, but it usually happens not too long after I wake up or when I've been eating really healthy foods. I passed out yesterday, I don't have the flu or any illness and I'd eaten pancakes with syrup for breakfast so it's not like my blood sugar was supposed to be low. 3 days ago I was like this when I got up but I ate some pudding and felt better. I eat a lot of sugary things but I'm at a very healthy weight (110 pounds, 5'5"). I am unable to gain weight. I get very very thirsty sometimes but I don't think it's the diabetic kind because then I go back to the low blood sugar thing. Then I'm not thirsty, I just get very nauseous regularly and my face gets all tingly and I start shaking and my vision gets weird. My vision gets blurry sometimes too, I got my eyes checked recently and I got glasses but it isn't the same kind of blurry, it's just like there's a cloud over my eyes. I get even thirstier when I drink things, when I am thirsty. Could this possibly turn into diabetes eventually? I'm sick of getting so nauseous and light headed and vomiting and dry heaving all the time.
