a large amount of people that develop t2 db are overweight, therefore statistically they are more likely to get these problems, plus the high sugar levels do damage to all sorts of parts of the body including the vital organs so yes its true but with good control id say its a lot less likely to happen, remembering too many and the majority of diabetics follow the normal advice from the medical profession and get ill whilst thinking they are doing the right things, on the day of diagnosis i was told i was 5 years away from major organ failure, since changing my ways id say that number would be an awful lot higher, so in mine and many others cases im sure, diabetes has prolonged my life tenfold
this is all just my opinion
