Yes, inducing vomiting intentionally after eating in order to make room for more food can be considered a form of bulimia. The behavior you described is known as "purging disorder," which is a subtype of bulimia nervosa in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
Bulimia nervosa is an eating disorder characterized by recurrent episodes of binge eating (consuming large amounts of food in a short period) followed by compensatory behaviors to prevent weight gain. Purging is one of the common compensatory behaviors, which also includes the misuse of laxatives, diuretics, or excessive exercise.
Purging disorder involves the same pattern of recurrent binge eating but without the regular use of other compensatory behaviors like excessive exercise or the misuse of laxatives. Instead, individuals with purging disorder primarily use self-induced vomiting to get rid of the excess food and avoid weight gain.
Regardless of the specific subtype, any form of disordered eating and purging can be harmful to both physical and mental health. It's important to recognize the signs and seek professional help if you're engaging in such behaviors. A healthcare provider or a mental health professional can provide a proper diagnosis, offer appropriate treatment options, and support you in your recovery journey. Early intervention can improve outcomes and prevent the development of further health complications.
