Illness anxiety disorder (previously called hypochondriasis, a term which has been revised in the DSM-5 due to its disparaging connotation) is a psychiatric disorder defined by excessive worry about having or developing a serious undiagnosed medical condition. People with an illness anxiety disorder (IAD) experience persistent anxiety or fear of developing or having a serious medical illness that adversely affects their daily life. This fear persists despite normal physical examination and laboratory testing results. People suffering from IAD pay excessive attention to normal bodily sensations (such as functions of digestion or sweating) and misinterpret these sensations as indicators of severe disease. IAD is typically a chronic condition.
疾病焦虑障碍（以前称为疑病症，由于其贬义内涵，该术语在《精神疾病诊断与统计手册》第5版中已被修订）是一种精神障碍，其定义为过度担心患有或患上严重的未确诊疾病。患有疾病焦虑障碍（IAD）的人会持续焦虑或害怕患上严重疾病，这对他们的日常生活产生不利影响。尽管体格检查和实验室检测结果正常，这种恐惧仍然存在。患有IAD的人会过度关注正常的身体感觉（如消化或出汗功能），并将这些感觉误解为严重疾病的指标。IAD通常是一种慢性病。
