It has been said many times in the forums, conference calls, and meetups, that the most difficult aspect of undergoing any odor-management protocol is to not have feedback about one’s odor levels, as family members and the sufferer seem to have, or develop, an anosmia to the body odors. It is not clear why this should be. The 2 main theories are that they have become acclimatized to the odor, or there is some sort of 'anosmia immunity' from smelling the body odors. Perhaps the saddest irony about the problem is that the sufferer has no way of monitoring their condition as a result.

So, what options does a sufferer have to measure his/her odor levels? Apart from purchasing very expensive equipment that would have the capacity to measure only some odorous compounds, which is not practical anyhow, there is also another option - to obtain a Trimethylaminuria Medical Alert Service Dog (SD) trained specifically to give immediate feedback not only about whether a sufferer has odor, but to also indicate if the odor is at a high or low level. The main aim would be to help the person understand their 'smell pattern', Humans acclimate to scent in a room - dogs never doso that perhaps they could alter their diet to suit, to better understand what triggers it, and to plan social activities accordingly.
