Bariatric surgery patients are welcome if medically stable. Patients with current disordered eating that does not rise to the level of a formal diagnosis of anorexia or bulimia, or with a past history of anorexia or bulimia in sustained remission, will be evaluated on a case-by-case basis at the first appointment. Dr. Tillberg looks forward to meeting you.
