Hi mickthered and welcome to the forum.
To be honest it is extremely unusual for a T2 on oral meds to be referred to a specialist diabetic unit, most T2's will only ever see a practice nurse at their local GP surgery who usually run what is called their Diabetes clinic, this nurse will usually also deal with the respiratory clinic looking after asthmatics and also any other special clinics the GP surgery operates. Their specialist knowledge is not very good in many cases, I had my care transferred to my local GP's clinic when I was on insulin and when I asked the "diabetes nurse" a question she said "sorry but I dont know much about insulin"!! She also tests my lung function twice a year at the respiratory clinic. She is very nice but has not got the qualifications of an endo or a respiratory consultant.
So you should consider yourself very lucky indeed to be referred at all :clap:
