I would while you are at the doc, asked for hubby to be refered to the hospital consultant, I personally under the circumstances request that a hospital visit is arranged for that day with the hospital diabetic team, so the can start him off on his insulin regime..
As he will need to have several (lots) of things explained, firstly how to load the insulin pen and attach a needle, best practice and how to inject.. when to test, what to include in his record diary (my opinion the more info, the better picture painted) how to use keto sticks, sick day rules and hopefully straight onto a carb counting regime...
Ask the what courses they do for diabetics and ask to be enlisted asap..
And of cause there is always us lot here who will give as much informtaion as possible..
Large learning curve, but don't worry it does get easier as you and hubby get your heads around it all..
Remeber no question is silly if you don't know the answer
