Diabetes Type 1 Support Group
Childhood","Childhood diabetes is when the pancreas in a child does not produce enough insulin on its own. In order to survive, insulin injections need to be incorporated as well as diet regulation. If your child is diagnosed with diabetes, find support and share your experiences here. Caring for a child with diabetes is challenging. We're here for you."
I did a very similar thing when I was going through high school, and in retrospect, it was all because I wanted some control over myself. I'd sneak snacks before my parents got home from work and when they went to bed. I knew I could hurt myself with this, but I felt like I knew my body and diabetes well enough to know that I wouldn't actually get hurt. Of course, even though I thought I knew what I was doing, that's probably where my mom got all of her grey hair.
My best advice is to talk to your son about a couple of things. Like how well does he know his diabetes? There's a chance that he just feels comfortable with himself, despite the low blood sugars. If that's the case, you can work from there to try and mediate a solution, such as him at least telling or texting you when he does self-medicate. Does your son use an insulin pump, or shots?
