I'm 14 and I've been wondering recently if I could have Diabetes. I have passed out from low blood sugar before (Almost twice), I'm frequently thirty and tired, and we even tested my blood sugar after a meal once with my sister's Glucometer that she has for an un-diabetes related condition. It was 306.

After big meals I often feel woozy, nauseated, and really hot after meals. This is exactly the same way I felt when I had the 306.

Could I have diabetes and should I see a doctor?
