Cashman JR[19] found that 53% of TMAU and 59% of non-TMAU subjects suffered from regular halitosis, dental plaque on the back of the tongue, which produced on average "200-600 ppb of sulfurous/fecal smelling volatile sulfur compounds (i.e., VSC: hydrogen sulfide; methylmercaptan; dimethylsulfide) with each exhalation, creating a malodorous cloud in their vicinity. Secondary trimethylaminuria occurs as the result of treatment with large doses of dietary precursors of the offending chemical. Findings found that the use of fecal/sewage as a description, and the use of multiple descriptors of the smell, and 'incorrect' locations of smell origin effectively differentiated ORS from TMAU. unbalanced microbiome, may increase TMA production, as may bacterial vaginosis (BV).
