Objective
To explore the reasons why eating disorder patients consume non‐alcoholic fluids and to examine variables associated with poor and excessive drinking.
Methods
A sample of 115 patients admitted for inpatient treatment to a specialist eating disorder facility completed a semi‐standardised retrospective fluid intake history of type and amount of fluid and of reasons for drinking. ANOVA, chi‐square and factor analysis were performed.
Results
The main reasons for consuming fluids were for fullness and appetite suppression; for feelings of control including feeling empty; to assist with purging; and for physiological reasons such as drinking when thirsty, after exercising and to increase energy levels via caffeine ingestion.
Discussion
An eating disorder needs to be considered a disorder of fluid intake, as much as a disorder of food intake. Factors affecting the fluid intake of eating disorder patients are related to the presence of eating disorder behaviours. Copyright © 2010 John Wiley & Sons, Ltd and Eating Disorders Association.
