I've been diagnosed as type 1 since 16. Am now in my mid 30s and have found out I have PCOS, which you're born with. But according to what I can read, PCOS normally leads to type 2 diabetes...not type 1. I have always had a problem with my weight, but at the time of diagnosis I had lost a bit and although this is linked to type 1 and due to my young age, I am a little in doubt as to if I have type 2 derived from PCOS. I know very little of type 2, so it's all a huge jungle to seek information, and my docs here have been absolutely unhelpful. Could I have been wrongly diagnosed with type 1 and how would I go about questioning this with doctors? Thanks in advance.
KPA - I think it' worth saying that PCOS is a pretty common condition, and it is likely there are plenty of women living with it who are never formally diagnosed.
To be honest, my take on the PCOS and diabetes thing is that any hormonal dis-regulation - such as occurs in PCOS, effectively means to individual's body isn't quite ticking over as it should
Saying PCOS leads to T2 is a bit like saying eating donuts, or chips, or cakes or whichever heavy carb foodstuff you care to think of leads to diabetes. It certainly won't help much, but it's way more complicated than that.
Sadly, there are juveniles diagnosed, correctly with T2 diabetes, however, in the scheme of things, they are not commonplace.
My guess on your situation (and it has to be a guess) would be that it is extremely likely your diagnosis was correct. That you also have PCOS may make you a bit more insulin resistant than some people living with T1. As a result, you might find your carb ration means you need higher insulin doses for certain foods than others do - but you need what you need.
Were I in your shoes, and it was really, really bothering me, I wouldn't bother trying to get anything done by my GP, but I would bring it up at my next clinic. There are tests available to measure how much, if any insulin you produce yourself. The main test is the C-Peptide test.
We do see people on here whose diagnosis has been changed, but it much more common for an adult to be diagnosed, mistakenly as T1, when they are indeed living with T1.
Good luck with it all. Niggling uncertainty is an uncomfortable way to live.
