I'm 43yrs old newly dx'd with what I guess is Type 2 diabetes based on at A1C of 6.7 and fasting BG of 146. GP has put me on diet/exercise only to manage which is working BG now ranges from 90-120. Do I need to find an Endo and have any additional tests done to determine the exact type. ie 1.5, 2 or whether I'm insulin resistant? Not sure what my next step should be?
