Apparently not.
They do not say exactly where. Colonoscopy ONLY goes through large intestines, and Chron’s is said to affect the small intestines. That is basically a guessing game unless there is a mass to see.
Most people having IBS/D issues at some point go through a colonoscopy. I know this is NHS in Britain but in 6 years she probably had one. So, I’m guessing it was in her small intestines.
I’ve had a bunch. Had a 3 centimeter polyp removed. Doc said it had 30 percent chance of being cancer. It wasn’t but I was supposed to follow up about 3 years ago :(
Better get around to it for another test.
