“Crohn’s is more a symptom than a cause sort of thing.”
I’m sure it’s just that to those that suffer from it.
I know of folks who've had Crohn's "cured" simply by having part of a bowel excised but still the cause of the offending inflamation was never discovered. With Celiac the cause is known and all too frequently the symptoms are identical to what is called Crohn's.
If eliminating wheat/barley/rye from the diet relieves the symptoms, it was Celiac ~
