Olfactory reference syndrome is a psychiatric condition where a person becomes preoccupied with the idea that they have an unpleasant body odor and that other people can smell it and are offended by it. Their preoccupation may focus on the fear that they have an overall bad body odor, offensive breath, a bad smell coming from their genital area, smelly underarms, bad odors coming from their anal region – or any or all of the above. They may be convinced that virtually any part of their body has a very offensive smell.
Not surprisingly, people with olfactory reference syndrome will go to very great lengths to mask or hide their “bad odor" from others. This includes repetitive bathing or the excessive use of perfumes, deodorants and mouthwash. Some visit the doctor's surgery in search of an answer as to why they smell and in extreme cases a minority of people have opted to have their tonsils removed to eliminate "bad breath".
Reassurances that they don't smell aren't enough to comfort people with olfactory reference syndrome and they'll go to great lengths not to sit close to anyone. They will also shield their face when talking to avoid offending people nearby with their perceived mouth odor. So sensitive are people with olfactory reference syndrome to exposing others to their smell that they avoid public situations. According to research by Malasi, El-Hiru and Mirza published in the British Journal of Psychiatry, this can lead to complete social isolation for people who don’t get help
How many people are affected by this condition? No one knows for sure. But olfactory reference syndrome is not a rare condition as it is estimated that anywhere from 0.5% to 2% of the population has some features of this disorder.
