What does bulimia mean?
Bulimia is a serious eating disorder in which a person repeatedly eats large amounts of food in a short period — a binge — and then attempts to compensate through purging behaviours such as self-induced vomiting, laxative abuse, fasting, or intense exercise. Clinically known as bulimia nervosa, it differs from anorexia in that sufferers are often of normal weight, which helps explain why the condition frequently goes unnoticed. The term derives from Greek roots meaning 'ox-hunger', originally describing ravenous appetite, and the older medical sense of insatiable hunger still appears occasionally in clinical texts. Today, however, 'bulimia' overwhelmingly denotes the psychiatric condition, discussed in medical, journalistic, and everyday contexts alike. Because it concerns mental health, the word is used seriously and compassionately, typically appearing in phrases like 'suffer from bulimia', 'recover from bulimia', or 'a history of bulimia'.
An eating disorder characterized by recurrent episodes of binge eating followed by compensatory behaviours such as vomiting, laxative misuse, fasting, or excessive exercise; formally called bulimia nervosa.
"Her bulimia went undetected for years because she maintained a normal body weight."
Often used interchangeably with 'bulimia nervosa'; the shorter form is more common in general speech.
Abnormally insatiable hunger or appetite, especially as a symptom of certain medical conditions.
"Patients with uncontrolled diabetes may experience bulimia alongside extreme thirst."
An older, largely historical sense retained mainly in medical literature.
Rarely pluralized; the word is normally used as an uncountable noun referring to the condition in general. A plural form appears only when distinguishing types or individual cases.
"Clinicians distinguish several distinct bulimias in older diagnostic literature."
The word 'bulimia' comes from Greek words meaning 'ox-hunger' — an appetite as ravenous as an ox's — yet it describes a condition often hidden behind a normal body weight.

Etymology of bulimia
Bulimia comes from the Greek 'boulimia', formed from 'bous' (ox) and 'limos' (hunger), literally meaning 'ox-hunger' — an appetite as enormous as that of an ox. The term entered English via New Latin and was used from around the late 17th century to describe pathological, insatiable hunger. In the 20th century, as the eating disorder was formally characterised, the term narrowed to denote the binge–purge syndrome, usually given the fuller name 'bulimia nervosa'. Related forms include the adjective 'bulimic'.

How bulimia is actually used
In modern clinical and everyday usage, 'bulimia' almost always refers to the eating disorder and is frequently used interchangeably with 'bulimia nervosa'. The older sense of excessive hunger survives mainly in medical literature. Because it names a mental health condition, the word carries a serious register and should be used sensitively rather than casually or humorously.
Easily confused with bulimia
Anorexia (nervosa) is an eating disorder marked by severe food restriction and dangerously low body weight, whereas bulimia involves cycles of binge eating followed by purging, often at a normal weight.
Bulimy is the older, now rare term for excessive or insatiable hunger, while bulimia in modern usage refers specifically to the eating disorder.
