Hamster going bald?

[Fudgepieces]

Really concerned about my fudge, she is around 2 years 1 month old and half of her and all of her underside is completely bald, at first I thought it was due to her getting older but from when I first noticed a few weeks ago it is getting worse and worse and I don't know what has caused her to go this bald (Photos of her are in attachments) she's otherwise completely active, but her mouth seems to hang open almost constantly (teeth aren't overgrown) and also seems to eat a lot more. The bald skin isn't irritated and she doesn't itch/scratch, only grooms herself. I'm so scared of taking her the vets as I know she really won't cope well as she is stressed so easily and I have no idea what is causing it

It's not easy to say for sure from your description what might be causing her to lose her fur, it is normal for them to get some hair loss or thinning as they get older & she is a good age, sometimes with females it can be a hormonal issue, if she's eating & drinking more it is a possibility she could have developed cushings disease but you would need to take her to the vet to get a proper diagnosis.
You could try giving her flax seeds which will help with general hair & skin condition as well as containing some phytoestrogens which could help with hormonal issues, tofu is good for that too, you could also give a drop of evening primrose oil on food & a tiny bit of brewers yeast (either crumbled tablets or flakes) which may also help.
I know it can be stressful for them going to the vet but if you have a good vet it shouldn't be too bad & it may help her if you know just what the problem is.
