Hi Jeannie and Sunday - thanks for your replies.
I have to be honest I was being quite simplistic and didn't really think through how complicated it would be to set up separate forums. The only thing I can think of is that we specify whether it's t1 or t2 related in the subject header when posting new threads, but that doesn't stop all people contributing (and shouldn't really). I just think it gets really complicated, especially for newly diagnosed t1s, when they get advice from t2s - I don't doubt for a second it's well meaning, of course. I guess we just need to point out to t2s that these are really two different diseases and maybe we call need to ponder a moment about whether the advice we give really is useful or not.
For any people reading who are not sure what the differences are I'll try to briefly explain:
Type 1 (was called Juvenile) usually occurs in young people and children. It's an autoimmune disease where the insulin-producing cells are attacked by our own antibodies (probably after a virus) and therefore the body no longer makes insulin. This is why we have to inject insulin.
Type 2 usually occurs in older people (but not always). It can be caused by lifestyle and/or genetic pre-disposition (I'm not implying that all people who develop it bring it on themselves, though) and happens because the body no longer can absorb the insulin even though it still makes it. Type 2s use any combination of diet, medication, exercise and insulin.
I don't know anything about gestational diabetes so I won't even comment about that, and there are other forms such as 'water' diabetes but I won't go into them either as I don't know much at all. I just wanted to point out how very different the types really are. I'm really not using this to attack anyone and would hate for anyone to be offended at all. The moderators especially are excellent here and I agree with what Sunday has said about Jeannie.
