I have a family history of type 1 diabetes - my mom has it, and so does an aunt, a cousin, and my grandmother was the only one of six siblings who didn’t have it. I know it’s not impossible, but at the age of 30, it seems unlikely I’ll ever get it. (I hope. It’s kind of amazing to me, after a lifetime of my mom prepping me for the time when I would have to give up sugar and start giving myself insulin injections.)
But - am I at high risk of coming down with type 2 diabetes? One of my aunts - who’s crazy and in terrible health - has it, but I’m not sure that’s much of an indicator.
FWIW, I’m in relatively good health now, as far as I know. My diet could be better, but it could be a lot worse, too. (I have a terrible sweet tooth, but I’m also a vegetarian, so it’s not like I’m eating Big Macs every day either.)
You’re almost certainly not at increased risk of Type II diabetes. Both type I and type II diabetes do have elements of inherited susceptibility, but separately: being at high risk of one doesn’t make you high risk for the other.
However, as a disclaimer, while Type I diabetes most typically starts in the young, I don’t know at what age you can start to presume you are “safe” and will never get it. I do think that at 30 it’s substantially less likely.
If you’re in otherwise good health, your terrible sweet teeth may not be enough to put you over the edge (depending on how “terrible” it actually is). I still occasionally overindulge on the chocolate goodies, but as of my last test results, both my glucose level and A1C were normal, and those results are a major factor in a diagnosis for Type 2, from what I understand.
I’d say to mention it at your next doctor appointment, to put your mind at ease, but you probably don’t need to schedule an extra appointment on the matter.
