Is that narrowed section situated after the distended loop of the bowel? Was it called a stricture in the report (which may cause partial obstructions and bloatings)? Or is it just a minor narrowing?
I have a distended loop of the small intestine myself, up to about 8 cm which is more like a colons's diameter. I don't know for sure what caused it, either bloatings over the years or an obstruction I had in 2005. I've been feeling well during the last years, thanks to chronic antibiotics to treat chronic pouchitis.
I don't think your enlarged uterus is correlated to the bowel.
