Its either constipated or has an internal bacterial infection. You could try adding 1 tps. of epsom salt for each 2 gallons of water in your tank, also try feeding the fish some deshelled green peas as a laxative(at least try even if the fish is rejecting food some goldfish are more willing to except certain foods over others). Now the second best thing to do is to take the fish to a piscine vet and have them give your fish some antibacterial injections which should kill off the infection and solve the problem, but for many people this is not a practical option since the nearest piscine vet may be over 100 miles away so if you cannot take your fish to a vet try treating the water with an antibiotic medication.
