<P> BIID is typically accompanied by the desire to amputate one or more healthy limbs . It also includes the desire for other forms of disability, as in the case of a woman who intentionally blinded herself . BIID can be associated with apotemnophilia, sexual arousal based on the image of one's self as an amputee . The cause of BIID is unknown . One hypothesis states that it results from a neurological failing of the brain's inner body mapping function (located in the right parietal lobe) to incorporate the affected limb in its understanding of the body's physical form . </P> <P> Sufferers of BIID are uncomfortable with a part of their body, such as a limb, and feel confident that removing or disabling this part of their body will relieve their discomfort . Sufferers may have intense feelings of envy toward amputees . They may pretend that they are an amputee, both in public and in private . Sufferers experience the above symptoms as being strange and unnatural . They may try to injure themselves to require the amputation of that limb . They are generally ashamed of their thoughts and may try to hide them from others, including therapists and health care professionals . </P> <P> The majority of BIID sufferers are white middle - aged males, although this discrepancy may not be nearly as large as previously thought . Most commonly an above - the - knee amputation of the left leg is desired, but amputations may also involve the arms, or instead manifest itself as a need for paralysis, or involve the senses, such as hearing or vision . </P> <P> A sexual motivation for being or looking like an amputee is called apotemnophilia . In addition, apotemnophilia should not be mistaken for acrotomophilia, which describes a person who is sexually attracted to other people who are already missing limbs . However, many of the people who experience one also experience the other . </P>
