What a bunch of horse excrements! As of this date, there has been no reputable peer review study indicating cause and effect relationship b/w halitosis and systemic disease. In contrast, there is a growing body of evidences indication strong correlation only! Presenting only anecdotal evidences, CSVN physicians and hearsay to jump to this conclusion only indicates a profound lack of the basic sciences and medical practice. But what do you expect from CSVN medical research? LMFAO

Halitosis can result from the following:
1) Diets, smoking, chewing tobacco (or any other leaves/spices) or any other abnormal oral habits
2) Food accumulation on teeth & tongue - primarily
3) Dentally related problems such as caries, periodontal diseases, abscess & etc...
3) If the above are ruled out as causes, then look @ GI issues
