Just seeing you post there Joe, reminded me that you know about materia medica.
A friend of mine has a 9 year daughter who was rushed to the hospital with sudden onset juvenile diabetes ... poor little thing is now stuck with needles and insulin. Do you know what causes this?
Do you definitely mean Type 1 diabetes (think that's what juvenile diabetes is now caused)?
It's autoimmune and mostly genetic I believe. Can be sudden onset around that age - did she go into diabetic coma or something?
The only good thing is that it's more easily managed and you're not so predisposed to all the awful consequences that you are with Type 2 - you do have to keep on top of it though and keep blood glucose levels within normal ranges.
I saw a programme a few months back about kids with diabetes in London - so many of those featured just didn't bother to attend their clinic appointments or check their blood glucose levels, then were surprised when they went into a diabetic coma.
