How to diagnose bulimia nervosa
Examine eating patterns for signs of bingeing.
Binge eating, or feeling compelled to overeat, is one of the main symptoms of bulimia. Common signs of bingeing include eating large quantities of food in a short time, even when not hungry; eating alone; hoarding food; or hiding empty food containers.
Don't confuse bingeing with regular overeating. Everyone overeats sometimes, and it's generally not considered a problem unless it is a common occurrence.
