So, no, I don't believe Type IIs simply wear out their beta cells. There's something else at work ~ with a genetic link ~ that slows beta cell insulin production.
That was just the quickest source of information on why you can’t be at type 2 that turns into a type 1 since the description of the dieases are based upon cause. I base what I know on what my endo tells me about the two very different dieases.
