There is often such a class of patients, mainly adolescents in the adolescent stage, they think that their own or fox, or bad breath, or the odor of the lower body, or the smell of sweat, or the smell of “body” can be smelled by others, causing others to resent, and will think that some whispers are talking about them, that others Smell. These patients often do not think they have a psychological problem, but insist on two points: 1. 2. Other people do smell it. For these two points: 1, these parts would not have been odorless, sweating more often than not, they insist that the existence of the smell, often within the normal range, in the normal social distance is simply impossible to smell, around the parents and classmates teachers can not smell what obvious smell, and they themselves feel that others are comforting themselves, not to tell the truth. 2, others do not smell, they will think that others smell, others are not talking about him, he will be others some words of some words to understand in response to their own, others some pinch nose cover mouth turn head avoidance and other actions to understand that others smell their body odor, in fact, these actions are very common, can not represent anything. There are also some people, once did have armpit odor, in fact, after treatment has been cured, but still feel that others can smell. For this case, it belongs to a psychological disorder, and there is no medical name that exactly matches the diagnosis of this symptom, some people call it body odor terror. It is a condition between obsessive-compulsive disorder and a state of paranoia. This problem, psychologically, is associated with the patient’s perfectionist tendencies, low self-esteem, strict education, and poor interpersonal relationships. Both medication and psychotherapy are needed. Active treatment is curable. This disease can cause the person so much pain that he or she cannot finish school properly, take time off from school, etc. Therefore, prompt consultation to the psychology department is a must, instead of continuing to other departments to check the causes that produce the taste.
