Introduction: Recent evidence suggests that incidence of Anorexia nervosa (AN) has remained stable over the last decades in Western Europe, while decreasing for Bulimia nervosa (BN). It is well‐known that most individuals with an ED (Eating disorder) do not seek medical treatment. Objective: The present study analyses hospitalizations related with EDs held in mainland Portuguese public hospitals between 2000 and 2014. Method: A retrospective observational study was performed gathering all inpatient episodes with primary or secondary diagnosis of ED. Number of patients, gender, mean age at discharge, suicide‐attempts related hospitalizations, in‐hospital mortality, length of stay, and mean charges were analyzed. Results: There were a total of 4,485 hospitalizations with an associated ED. AN was the most frequent ED (n = 2,806). Suicide attempt‐related hospitalizations were most common among patients with BN (10.1% of BN hospitalizations) or AN (5.2% of AN hospitalizations). Discussion: AN has higher in‐hospital mortality than BN. We observed a higher proportion of suicide related hospitalizations in BN when compared to AN. Although pica, rumination disorder, and psychogenic vomiting represent a smaller portion of all EDs, this study was the first to describe hospitalization trends for this set of EDs for a 15‐year period, to the best of our knowledge.
