特別愛去健身房、老覺得身材不夠強壯？小心哦，有可能得了恐瘦癥。英國身體畸形恐懼癥基金會主席羅布·威爾森說，英國健身房里大約10%的男性會員有恐瘦癥。

Muscle dysmorphia, also known as "bigorexia", may now be affecting one in 10 men who visit gyms in the UK, according to the Body Dysmorphic Disorder Foundation.
英國身體畸形恐懼癥基金會指出，英國健身房里大約10%的男性會員有肌肉上癮癥或健身過度癥，也被稱為“恐瘦癥”。

It is an anxiety disorder which causes someone to see themselves as small, despite being big and muscular. Workout is their top priority, they would feel depressed if they miss one session of fitness training. It is sometimes described as a kind of "reverse anorexia".
這其實是一種焦慮癥，本來外形高達健碩的人卻總覺得自己太瘦小。健身鍛煉是他們的首要任務，如果錯過了一次訓練，他們就會沮喪不已。這種情況有時也被描述為“逆向厭食癥”。

The cause of muscle dysmorphia is not clear. The NHS states it may be genetic or caused by a chemical imbalance in the brain.
這種肌肉上癮癥的誘因尚不清楚。英國國家醫療服務體系認為可能是基因導致的或者由于大腦內部某種化學物質失衡導致的。
