My dad is a T2 diabetic and is supposed to be starting insulin this week. Since I'm the insulin expert in the family, he's asked me to help him. Some background-- he's 71, was diagnosed some 20 years ago and has never done much to take care of himself aside from taking his oral meds. He rarely ever tests himself. My mother is losing her battle with breast cancer, which adds to his stress (and he's a stress eater!) and it's all finally going to hit the fan. His doctor prescribed 2 units of lantus each day with a pen. If he got more instruction than that, he hasn't said. So, my question is, for a 300+ lb man with insulin resistance, is 2 units of insulin even going to do anything? I know he needs to be testing himself at least several times a day, but should he also be carb counting? It seems like if your carb intake varies wildly from day to day, find finding the right Lantus dose would be really hard even for a T2 diabetic. I know how I would treat this it were me taking the insulin, but I know my dad can't or won't do what's required to really get his blood sugar under control. So while I would love to be aggressive and get his blood sugar down (which is likely in the high 200s and 300s) I wouldn't want to risk lows for him either. I want to help him, but I'm already discouraged. I know he'd inject the 2 units of insulin and think it's enough and continue with his poor eating habits.
