lenaw, diabetes care has changed dramatically over the years, diabetes is not the scary problem it used to be as long as advice is followed (not like my grandad who had type 2 and when he fancied a cream cake, he would take an extra pill to compensate )
It is unusual in my experience to have CAT scans but I am not up on newly diagnosed diabetics at the moment and what tests they have but I wouldn't worry about it as it shows they are looking after him which can only be good.
everything in moderation is the key phrase.
there are so many good books out there that can help with food/diet etc. on the shelf at the side of me, I can count at least 20 books on diabetes without delving too deeply so there is plenty of choice to suit your needs.
the best thing I can say to my clients with diabetes is to take this in a positive way and use it as a good excuse to be healthy and for the family to be healthy too. if everyone in the house eats like a diabetic should, 1 it is easier to as everyone eats the same and no special diets, and 2, you find eating healthier like this improves everyones health and 3 DH gets support and help without it being a drain on everyones emotion.
just remember, diabetes, if managed correctly and sensibly is not the life threatening condition it once was, with increased awareness and treatments, the severity of the complications of diabetes are greatly reduced nowadays, the only notable problem I ever found was that half the fridge shelves are taken up with ''insulin pens'' and vials which meant I had to get my mum a bigger fridge
so the important thing is to look at the positives on this, there is help, support, new treatments out there to get you through this but also, think of this as the beginning of a new healthier lifestyle for you all, one that will benefit the whole family.
ps my mum does have the odd cream cake and eats biscuits and she can eat her favourite veg, the parsnip too!! (when you get round to reading the glycaemic index charts, you will find out why I mentioned the parsnip )
