(I swear I am not trying to take away from the seriousness of this conversation)
I have heard and agree with all points that people have made as to how we got diabetes. Here's my story about how I think I got it...
It was a fateful July Saturday in 2004 when I went to a friend's party at noon. From that time on until 10p, all I did was drink, eat, and sit in a hot-tub. At one point, I was so drunk that I was in the hot-tub for 4 hours because I had passed out. I woke up, got out, and drank some more and ate more crap. I threw my guts up that night and the next morning is when I started to feel real thirsty and started to urinate every hour or so. I let this go on for about 5 weeks (the thirst and urination) before I went to a doctor and found out I was diabetic and in DKA at that time.
The point of the story is this: for me, I have this event in my head that is the "trigger" for my diabetes. Before that day, I felt I was normal and healthy. Did the excessive heat or chemicals from the hot tub "trigger" my auto immune response to stop producing insulin? Was it the excessive drinking? The bad eating? I don't know, but it proves to me that some T1's have triggers that start the disease. I am the only person in my family with it as well, so how was I pre-determined to get it? Would I have gotten it if that day did not go down that way? I doubt it, as something else would have triggered my immune system to attack and destroy my naturally produced insulin. It leads me to believe that indeed there is something in our body that could have told us sooner that we were going to be T1's and that maybe, with enough research, someone can find that marker and "fix" it so that the disease does not happen, hence a cure.
