Hmmm, Ive personally never heard anything about bad breath being linked to Crohns.
But I did a little search about it and this is what I came up with...
In Naturopathic medicine, bad breath is often indicative of improper digestion
& elimination of foods, toxaemia or defective elimination via the liver, kidneys, colon & skin.
And on a search on IBS one of the symptoms was bad breath.
