I'm wondering what kind of tests does a doctor do if he suspects i have an eating disorder?

Specialists will: Assess the disorder, take full history of your relationship with food, your level of functioning (family history, work history, relationships, etc), do medical evaluation 2 see if there are serious physical complications, they will decide what level of treatment you need, out-patient, day treatment, in-patient, support groups, individual and or family therapy. Then they'll make recommendations.
