If it's a hybrid or Campbell's then yes they are prone to diabetes & you need to take a little extra care with diet.
Just avoid any sweet or sugary treats (including honey) stick to veg rather than fruit & don't feed the sweeter veg very often, ok just as a treat now & then.
It's best to feed a sugar'fruit free dwarf specific mix like Burgess dwarf hamster harvest (available from most pet shops & online) or Bunny Dwarf HamsterDream Expert which is only available from Zooplus here.
They tend to need a little more protein than syrians so it's a good idea to supplement their diet with a few extra mealworms which they love.
