總是擔心身體不適，動不動就跑去醫院找醫生診斷，即使拿到完全正常的檢查報告也無法打消自己的顧慮……現代人生活節奏加快，壓力增大，小心患上疑病癥。

Hypochondria refers to an excessive preoccupation with one's health, usually focusing on some particular symptom, as cardiac or gastric problems.
疑病癥指的是過度擔憂個人健康問題，通常集中于某些特定的癥狀，比如心臟或者胃部不適。

This debilitating condition is the result of an inaccurate perception of the condition of body or mind despite the absence of an actual medical diagnosis.
這種讓人衰弱的癥狀是由于盡管缺乏確實的醫療診斷，但對個人的身體或精神狀況認識不準確。

An individual suffering from hypochondriasis is known as a hypochondriac.
患有疑病癥的人就稱為疑病患者。

Hypochondriacs become unduly alarmed about any physical or psychological symptoms they detect, no matter how minor the symptom may be, and are convinced that they have, or are about to be diagnosed with, a serious illness.
疑病患者對自己發現的任何身體或心理癥狀過度擔憂，無論這些癥狀多么輕微。他們相信自己已經患上或者即將患上嚴重疾病。
