HiDo you mean like a bowel lining prolapse?Quite a while ago I saw a surgeon who said that I had a mucosal prolapse and that that could be causing my symptoms - he tried a non-surgical treatment without success and consequently offered to do surgery, which I declined due to it not being a 100% guaranteed success - I had seen this doctor as a private patientWhenever I have brought this up with other doctors I have seen on the NHS (I'm from the UK), they were not willing to carry out the surgery on someone of my age (31 now) - they carried out tests on me and said that I was within 'normal limits' and should just try and manage thingsI am quite sure that I have some form of internal bowel lining prolapse, and at times it can feel more obvious.... and there are certain things which can make it worse for me, like exercise for exampleSurgery however just seems like too much of a risk
