hello,
I would say that my advise would be to keep a close eye on him, ie eating, drinking, peeing, pooping and behavior.. Call your vet, register the concern, and see how things go. Ask to be scheduled for the next available appointment. If he hasnt had his annual exam, or blood work/diagnostics in the last 3-6 months it is probably a prudent thing to do,
good luck

Hello,
Without knowing your pet I would say the options are to recheck for the polyp (they can recur), try a barrage of medications to see if any help, or wait and see what happens , or see the specialist. There I’m not sure this is helpful but it’s the best I’ve got. Good luck
