Re: Personality changes in type II Diabetic
It sounds as if this could all be coming from poor blood sugar control. It's not at all uncommon for people to become combative when their blood sugar drops.
You need to talk to his doctor as well. It's quite dangerous for him to be driving if he's having lows. He needs to be testing much more frequently, and he should NEVER get in a car (at least, not in the driver's seat!) without testing first to make sure his blood sugar is at a level that's safe for him to be driving. Additionally, on a long trip, he needs to stop and test once an hour.
Sure, he might be depressed...that's a LOT to go through, between the illnesses, the move, etc. But everything will go better if his blood sugar is under better control. What type of insulin is he on? It's a lot harder to adjust for weight loss if he's on a mix, but if he's on Lantus and a rapid-acting insulin, he could adjust his basal insulin (Lantus) down a bit as soon as he starts having 2-3 lows in a few days. I'm on a pump, so I use only rapid-acting insulin (Humalog), but I'm also losing weight, and I self-adjust. What I do is lower my basal rate by about .1 unit/hour if I start having a lot of lows. But I also test frequently...4-6 times a day at normal times, 6-10 times a day if I suspect I might be going into a problem period (like, when I'm sticking to a weight-loss diet or getting more regular exercise.)
His doctor can explain all of this, but he needs to be made aware of just what's happening.
