Hi. I've been taking adderall since third grade. It has always helped me in school. I'm 20 now and go to University of Maryland. When I was 17 I was diagnosed with diabetes. It was not too surprising because my family has a history of diabetes, but after reading your situation, adderall may be the cause. I highly doubt that there is any chemical effect of adderall that caused diabetes, but it may have been triggered by the binge eating that can occur when the adderall is not taken. Adderall is known to be a hunger depressant. When I take it, I have absolutely no hunger and have to force myself to eat. When I don't take it, I eat everything in sight as if I am compensating for the days I took it. Diabetes is a genetic disease. For those that have the gene, its just a question of when it is triggered. And although your family doesn't have a history of diabetes, it may be a recessive gene. This means it would have been passed down through the generations of both parents, waiting to find a spouse that also has the recessive gene, in which case there is a 25% chance of the children receiving both recessive genes and therefor becoming a dominant trait.
