Hi happycat, I dont low carb, well not to the levels that some people do and far from progressing onto more and more medication I have gone the other way over the last 5 years, I started off taking insulin 4 injections a day and metformin the maximum dose, after 12 months I came off insulin and after Xmas this year I reduced my metformin down to two tablets a day from the four a day I was on. So its got nothing to do with low carb diets and everything to do with control, however you manage it.
My sister who is in her mid 60's now and my mother in law, a long term T2 who is now in her 70's are both well controlled, neither of them as a low carber and my MIL is diet only and my sis is just on Metformin so no one has to become obsessed with low carbing unless they want to. A reduction in carbs is a good idea and some thought about the right kind of carbs wont hurt but thats all that is necessary IMHO.
There is a very rare type of diabetes called LADA (
Latent
Autoimmune
Disease in
Adults) or T1.5 diabetes that is seen in some slim T2's but also bear in mind that 20% of diagnosed T2's are not overweight and they are not all LADA. But should in the unlikely event of you at some stage being diagnosed as LADA or T1.5 then you will have to go onto insulin, but even if this does occur you will get used to insulin injections just as I did and just as every T1 has to. But for the immediate future put that thought out of your head, your doctor is spelling out the worst scenario, and with a little care you should have nothing to fear but fear itself
