Eating disorder
Eating Disorder
Eating disorder (/ˈiːtɪŋ dɪsˈɔːrdər/) is a term for a range of psychological conditions characterized by abnormal or disturbed eating habits.
Etymology
The term "eating disorder" is derived from the English words "eating" and "disorder". "Eating" comes from the Old English 'etan' meaning to consume food, and "disorder" comes from the Latin 'dis-' meaning 'apart' and 'ordo' meaning 'order'. Thus, an eating disorder refers to a condition where the normal order of eating is disrupted.
