Regarding eating disorders: Please note that for patient safety, per Talkiatry policy, Dr. Tillberg is unable to work with patients with current active anorexia nervosa or bulimia nervosa (or significant relapse in the last 6 months), or with patients requiring current regular medical or lab monitoring for complications of binge-eating disorder or ARFID. 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.
