Oh, thank you for your reply! Yes, I can see how that can be a very common question and we must do our best to inform them. It's a good testament to character and intellect that one is able to find such complicated information and digest it on one's own. Sadly; many of us are not lucky enough to have such resources. Many of them will not speak any English and will have a difficult time browsing the internet to look for the answers they need.
You are probably aware of this by this point; but it is interesting to see that hypo- and hyperthyroidism is so often connected to diabetes. I have hypothyroidism myself and did not make this connection before looking through the scientifics. Just knowing that there's a connection kinda helped. As for PCOS I do not have any personal experience, as I lack the proper parts.
I hope things have gotten better with time. It can be difficult to have many afflictions at the same time, especially when one has to juggle information that oftentimes contradicts the GP!
