On the juvenation forums, a parent whose son was newly diagnosed with type-1 diabetes noticed that he would sometimes go into angry fits when experiencing rapid swings in blood sugar. Since it had never happened until a few weeks ago, she worried alot about this new Jeckyll and Hyde behavior.
It may be comforting for her to know that this isn't so uncommon. Nearly twenty years ago, researchers at the University of Virginia published a study entitled, Mood changes associated with blood glucose fluctuations in insulin-dependent diabetes mellitus.
We've witnessed first hand that mood shifts often happen with dramatic fluctuations in blood sugar. We've found it very challenging at times to "reason" with our daughter during these episodes and it makes it hard to treat a really bad high or low. The net takeaway- they're not themselves. They don't mean to be hateful. They feel guilty afterward.
But most importantly, they still need your help even if they're fighting you in this delusional state.
So DON'T take any attacks on you personally. DO try to stay calm throughout the fit. It's hard and can be mentally exhausting, but you can all get through it together.
