Your symptoms of shedding from the rectal stump is what is called diversion colitis
, which is fairly common after getting an ileostomy
. Treatment is usually not necessary and it actually can resolve on its own after a few months or years, as it appears to have happened in your case.
I would not be concerned at this time, just keep your regular doctors appointments. If you actually develop bleeding you do need to see a gastroenterologist for further evaluation.
Hope that helps, let me know if you have further questions
