ill hamster?help

Question
I have a syrian hamster about a year old and was very active and inquistive always getting up at meal time until yesterday.Now she seems to be lethargic and not getting out of bed. I have noticed she isn't eating and will not really take any food when offered. I have held her and her breathing seems ok, maybe only a watery eye which cleared up and she will walk out for a bit but then will just go straight back to bed. can you help?

Answer
during winter some hamsters may be less active,. but it doesn't stop them from eating. my hamster is less active but he still eats like nobody's business. i'f he's not interested in food i would consider taking her to a vet to get checked up. she may have a bacterial infection.
