Why doctors/family members may not smell us

It is possible that family members don't smell anything.
Here's some information:

Why isn't metabolic Body Odor s obvious to family and doctors ?

While keeping in mind that there is a wide range of perception abilities of any given scent at any given moment in time in the human Olfactory System, there are a few theories about this, and the most likely may be that very few sufferers of metabolic Body Odor s seem to smell all the time and so may not smell at a doctor's visit. There also appears to be another factor in which genetic relatives, family, and 'loved ones' often insist they have never detected the sufferer's odor, or have in very rare instances. Why this would be is currently unknown. Some think that 'loved ones' will become 'desensitized' to the odor problem (acclimatization), especially with prolonged exposure. Another theory is that perhaps 'non-smelly non-smellers' are in fact 'carriers' of whatever enzyme(s) flaw may be involved. At the moment, it is unknown with any certainty why some people cannot seem to smell someone when they are smelling.
