病人诉称味觉和嗅觉异常是比较常见的,但造成这种痛苦的原因各人不同。嗅觉异常不象丧失听觉或视觉那样严重。在有些情况下,如有感冒或枯草热时,嗅觉虽暂时异常,但是严重的。只有当症状持续相当时间,许多病人才确实感到他已失了一种官能。 当面对失去嗅觉的病人就称之为“无嗅觉症”或就去考虑他本身的病能否治愈的做法是错误的。如果承认它仅是一个症状,首先就需要找出它的原因,其次解决其能否或是否需要治疗。第一步是将症状分类,然后是其可能的原因。 Patients complain of abnormal taste and smell are more common, but the reasons for this pain are different. Olfactory abnormalities are not as severe as loss of hearing or vision. In some cases, when the flu or hay fever, smell although temporarily abnormal, but serious. Only when the symptoms persist for quite some time do many patients really feel that he has lost a function. When faced with loss of smell the patient calls it “no sense of smell” or go to consider whether his own disease can be cured is wrong. If you admit that it is only a symptom, you first need to find out why and, second, whether it can or will not require treatment. The first step is to classify the symptoms and then their possible causes.
