If your husband has been diagnosed with Crohn's , he still has Crohn's.
It might have been in remission but there is no cure for it as of today.
and upper endoscopy
was negative , Crohn's
can be in any part of the digestive tract from mouth down to anus.
If there is blood in the stool and he has anemia , he might need to have
a small bowel series or a capsule endoscopy
to see if his Crohn's is
reactivated. As for clay colored stool ,there may be problem with the
biliary tract. He might need to get complete pancreas
blood tests and
also stool tests to look for fat , He may have poorly functioning pancreas

I would suggest that your husband see a gastroenterologist for a thorough
I wish him well.
