Bad Breath Halitosis Forum

I've been to different ENT's over the past. They used endoscopy to examine and they all concluded that I don't really suffer from pnd. My tongue however is usually coated.

Could the problem then be coming from my stomach? What should I tell the doctor?? I just moved to a new location where I also got a new doctor. I want to give it another shot again. I guess I have nothing to lose.

ANy sort of advice would be appreciated.

Thanks in advance

What color phlegm do you cough up? Do you have chronic tonsil stones?
