NAY NAY ~ yes, that can happen -- gaining weight while in school. It is a good idea to try and eat healthier esp with diabetes in the family (mine too). It is easier when you are younger too. We have a 20-something thread here you might like to join and we do have a diabetes section in the Dieting with Obstacles Forum that you might like to read (for good info). I was diagnosed with PRE-diabetes myself and have gotten things under control through a healthier diet and exercise (mostly walking).
