Yes, they get bloated with what seemly is gas. I have one whom this is a semi regular occurrence. Mine actually has a bunch of medical issues, (rescue) She was born with birth defects that my vet and I believe has made it more common than normal.
I will suggest what I do you can take from my treatment what you will. I soak her once a day in warm water for at least 20 min. If she is eating (mine almost always is) I will offer a smaller prey item. I will treat the prey item with a bit of bene-bac for reptiles in water. I mix a bit in water so it can be used in a syringe. I will take the thawed rat and place the syringe into the dead rodents mouth and put as much water as it will hold. This gets fed. If the problem doesn't clear next feeding I use a small amount of human grade mineral oil in the rat, around 0.1ml per 200 gm of snake to a max of 1ml. This helps stool pass and loosen. If this fails it is time for the vet. Sadly stool in the belly that is partially blocked needs to be dealt with.
If the snake has suddenly stopped eating and soaking for five days has done nothing and /or the bloating is worse it is time for a vet.
