Just a question...Do you have a J pouch or K pouch? I have a K pouch and as a younger woman, I was chronically anemic...in the end, it was a combination of a number of factors...hard periods, endometriosis which caused incredible abdominal pain, and my stoma bleeding without my really taking notice of it...it always bled a few drops at every single intubation and a bit in the catheter...I never mentioned it to my obsgy because for me, it was so normal that it never occurred to me...it was only after he looked at it one day and saw the blood on the stoma cover that he asked if it was a frequent occurrence...I had to cauterize my stoma regularly after that (still do).
Do not always look for a single cause but the combination of numerous less important factors that can be at the origin of the problem.
