Some forms of Type 2 Diabetes can often be cured with radical diet change and weight loss, but not with drugs.. Type 1 can not be cured but if it comes up in childhood sometimes the children "grow out of it" sometimes they don't :(
My understanding is that Diabetes cannot be cured, but it can be controlled (I'm refering to type 2 diabetes. As long as I control my food closely, take my meds appropriately, then my levels will be somewhere near a high-normal, and less damage will be done. Definitely not an easy thing. However, I don't think it's cured, and if I once again start eating sweets, etc., then the damage will be starting again. Mostly it's because the cells will not receive the insulin very well, either because the pancreas is on it's last leg or whatever. So you eat sugar, high fat, and the glucose soars, and to offset that your body tries to produce insulin, but the cells won't take it, so your body produces more and more, then suddenly it's enough to go into the cells, but by then it's too MUCH insulin and it damages your vessels. The object is to keep a balance and not let your sugar levels go too high or too low.
