@J @Wormwood FWIW it may not be quite what they presented it as. We thought mine had PCOS because of what her old doctor told her, then when we popped the hood on her it turns out they never really tried to figure out what was up with her.
I would treat her a bit like a used car & maintenance: You don't know who did the work, so you can hold it somewhat suspect until she's under your care and then know you're doing it well and getting a correct DX.
