Answer
how old is your hamster? hamsters generally live 2-3 years. Does your hamster have any other symptoms such as a wet bottom and a lot of weight loss very fast? More than likely your hamster has a bacterial infection if he has shown these symptoms. If your hamster doesn't show any of these symptoms than your hamster may be fine but is just slowing down because he's getting older if he's more than a year old. If he's still pretty young than I would go with a bacterial infection and the vet would be the best person to take him to since the vet can give him antibiotics.
