sorry to hear this Erin!
but dont worry you will get it under controll! 2 out of 3 of my hammies are diabetic! one is happy on a controlled diet the other struggles a little but she is older! after some research and especially help from vectis hamstery i stick to high fibre, high protein low fat diet with absolutely no sugar! this is what i feed ( not saying this is perfect im still learning but it seems to be working for my hammies!)
base: burgess dwarf supahamster ( with corn picked out)
added: linseed ( amazing for their coats), porridge oats ( slow gluten release), millet (sprays) and pearl barely (only a little)
fibre: timothy hay (they love this!) vitacraft alfafla buscuits ( they will eat these but not the pellets in the mix :s)
protein: mealworms (live/crushed heads!) also working on introducing dog buscuits!)
veggies: always greens broccoli, spinach ect. no fruits!
or sweetcorn/carrots/sweet peas too much sugar!
treats: peanuts and pumpkin seeds!
hope i am of some help! and like i said some of it may be wrong as i am learning atm aswell
