bad breath/body odour

Hi guys... i have had GERD for years and have managed to keep it undercontrol till last year when no drug would work, i just had this horrid bitter taste in my mouth and bad breath/body odour ... i was recently diagnosed with crohn's disease but have been told the odour was not from crohn's, but when i started on my medication, it went away for while, but now its back... can Gerd Cause horrid breath/body odour? i have been checked by an ENT, had kidneys checked, dentist checked out ok... im baffled .. im having severe drymouth and saliva glands seem to not be working right im on a new drug called periat, it  seems to help a bit  ... any suggestions?

GERD does cause bad breath problems and it is the acid reflux that causes it. I spoke to my doctor about what I can do for it and he suggested that I carry a travel size little bottle of mouthwash around with me. He strongly suggests not to eat mints (which causes heartburn) or chewing gum (which wakes up your stomach acids). Hope this helps.
