Olfactory Reference Syndrome

Olfactory Reference Syndrome

Information about ORS


Olfactory Reference Syndrome (ORS) is a psychological disorder in which an individual becomes excessively concerned about his or her odor. For example, an individual with ORS may worry that he/she has bad breath, when in reality this smell is completely normal. In ORS, preoccupation with one's body odor becomes time consuming and causes significant distress. In addition, a person with this disorder can become so worried about his/her odor that he or she is constantly checking, trying to mask, or talking about the imagined smell. He/she may even seek out the help of a physician, dentist, or gynecologist. As a result, ORS can seriously interfere with a person's life. Someone with this disorder may also have difficulty concentrating due to the odor related thoughts or have interpersonal problems.
