If it is female, it means she is in heat. If it is male, maybe worms are the culprit.
If it is a male it could be his testicles. They usually just appear all of a sudden when they become sexually mature and can sometimes be huge and could look like a swollen butt.
Hamsters do not have visible external sex organs, so it is difficult to determine the sex of a hamster just by looking at them. The size of a hamster's rear end is not an accurate way to determine their sex. It is best to consult a veterinarian or an experienced breeder to determine the sex of a hamster.
A healthy hamster is usually very alert, has a dry nose (not a damp, wet nose), has no discharge around the eyes, the coat is thick and shiny, the body shape is evenly cylindrical, and the 'anal' region should be clean (not covered in fecal matter).
Males are generally larger than females. Females have a more rounded rear end. It is difficult to identily the reproductive parts. The males do have testes, but they don't always descend or may descend late. While finding testes certainly means they are male, not finding them does not guarantee they are female.
nests are a safe haven to keep warm and rear the live young until they are big enough to fend for themselves
Hold your hamster on its back to look at the belly area. You can cup your hand over your hamster and gently turn it over onto its back, or hold the hamster by the scruff. Holding the hamster in a slightly upright ("sitting up") position will help you determine if testicles are present. The surest way to tell is by looking at the anogenital distance. This is the distance between the genital openings (penile opening in the male, vaginal and urinary openings in the female) and the anus. This distance is much shorter in females than males (in fact the openings can be difficult to distinguish in females while they are separated by about half an inch in males). The back end of the male tends to be elongated and rounder in appearance in comparison to the female (especially noticeable in Chinese hamsters). Males often have a noticeable scrotum with testicles after about 4 weeks of age, although the testicles can be retracted. Only females have nipples
It does, but mostly the lower part of the belly gets bigger when the hamster is pregnant.
If your hamster is bleeding from her rear take her to a vet ASAP. Hamsters do not have periods, not many animals do.

Not really no, but boy hamsters are generally larger at the rear end than girls because of their...ahem...."parts"
I have watched the National Geo channel and I feel like I remember hearing they do rear their young.
Yes they do

In what way does the rear end look strange? If there are any real concerns it would be best to get a check up if you can.
Rear as in rear end
