Is my hamster sick?

Question
Hello

Me and my younger sister both bought hamsters a couple moths ago. Mines a teddy and I think hers is too, except with slightly shorter hair. We feed them Premium Hamster/Gerbil complete diet. I also feed them a mixture of friut and veggies 2 times a week such as brocaly, cheese, milk, grapes, carrots cuted up and sometimes blended together. My hamster is perfectly health not to fat or skinny. But my sister's hamster is skinny,, sleeps to much, won't eat much of her diet. But will eat some veggies and fruit (but barely). And today while holding her she pooped diahrea on me hand(discusting).
So can you please help me find out why she's not eating, diahrea, sleep too much and skinny.

Thank you

Answer
Michelle,
as it says in my profile I don't know much about hamsters. I have a link where you can ask this question to a hamster expert.

Her name is Heather and she does all kinds of hamsters.

or you can ask here:

just look for the hamster link.
I can tell you this; the hamster is sick and should see a vet but go ahead and ask at one of those links first if you want.
You really need to take her to a vet that treats hamsters.
