This happens to goldfish quite often. The reason could be attributed to a disease called "Dropsy". When goldfish is suffering from dropsy, it can not excrete the undesired liquids out of its body, which start accumulating in its body. Dropsy can be fatal.It has a few types.
1: Acute Dropsy
Cause = Bacteria
2: Chronic Dropsy
Cause= Parasites or tumors.
You should keep the fish suffering from Dropsy separate, because it can be contagious. Salt baths for the sick fish might help in drawing the extra fluid out of its body.
