Diabetes could happen to everyone at any time.
Actually type 1 diabetes developes up to the age of 25. The highest rate of the disease lays between the age of 8 to 12. But there also are exceptions. Babies also could get the disease, adults over the age of 25 as well. It's not medically reviewed enough but type 1 diabetes nearly always results in an autoimmun reaction.
In contrast to that, the risk of getting type 2 diabetes can be reduced by your own behaviour. A healthy nourishment, high amount of sports an avoidance of overweight reduces the danger a lot. Most type 2 diabetes patiens are elderly people, because with an older age the pancreas produces less and less insulin.
