Hiya ZAZI...it may seem a bit hard to believe at this time but, there will be improvement. As a Type1 diagnosed at 37 just over 2 years ago, I remember well those weeks leading up to and just after diagnosis. My blood sugars and A1C were in the same ballpark as your hubby's.
The vision thing is scary (I couldn't even read giant highway signs till I was right under 'em), but, I can tell you that it is more than likely a symptom of the high blood sugar and it WILL improve along with the improved blood sugar control. I'm assuming he's started an insulin regimen?
Don't knock yourselves up about
having a hard time dealing with it either. It IS a difficult thing to be diagnosed with. You're whole life as you know it changes but, I can tell you that in some ways it changes for the better. It will be a learning process - and one that sometimes you wish would just go a little faster - but, if you grab the bull by the horns from the beginning, with an active interest in knowing how to manage with Diabetes (lifestyle changes), before long you may just find yourselves appreciating just how much healthier you are than many non-D's or (dare I say) some Diabetics just unwilling to change their lifestyles.
It starts with hubby understanding his insulin and/or insulin to food relationship. Getting with a Dietician/Nutritionist is, IMHO, imperative and a crutial first step in the process. I know the first few insulin shots can be a psycological struggle but, one comes to terms with it pretty quickly when you understand it's what keeps you alive and also, the short, thin, little needle tips are almost painless.
There's a lot to deal with all at once and it can be overwhelming at times so, don't fear that. It's par for the course sometimes with Diabetes. Just know he's not alone, ZAZI, and we're here to help answer any questions, share experiences or even just to listen. Wishing you/hubby well. Do stay in touch
