Can you be diagnosed as a bulimic if you are obese and you binge/purge several times a week?

Possibly: Obesity is not a requirement for the diagnosis of bulimia nervosa (bulimia). Binge eating (eating an extraordinarily large amount of food, and having a sense of lack of control over it) and inappropriate behaviors in order to prevent weight gain are the primary criteria for the diagnosis. The frequency of at least twice a week for at least 3 months is consistent with the diagnosis.

Bulimia : Binging then purging for any person at any age, sex or body size is unhealthy and can lead to serious medical problems. It is not a effective way to lose or maintain your weight. Your physician can help you lose weight safely and effectively. If you are having problems stopping you should seek help from your physician as this type of behavior can be associated with obsessive compulsive disorder.

Yes you can be : Yes you can be a and may be that is the beginning of bulemia in some.
