Background. Sleeve gastrectomy (SG) has become the primary bariatric surgery procedure in the U.S. Over 50% of people presenting for surgery have psychiatric diagnoses. The study purpose was to evaluate change in anxiety and depression symptoms and medication use after SG. Methods. Subjects completing SG with a diagnosis of anxiety and/or depression treated with medication were retrospectively identified from the electronic medical record (EMR) of Synergy Bariatrics, a department of the Erie County Medical Center. Phone outreach was made to complete seven-point global impression of change scale classifying symptom improvement or worsening in the 3- to 6-month postoperative period. Improvement or worsening was defined as either all reported symptoms improving or worsening or ≥1 improving or worsening while remaining unchanged. If ≥1 symptom improved and worsened, it was classified as mixed. No change required the same profile before and after surgery. Medication, dose, and changes were identified by EMR, verified during interview and classified as no change, discontinued, decreased, or increased. Results. 59 subjects completed the interview. 21 subjects were diagnosed with anxiety. 13 (62%) had no change in therapy and 5 (24%) decreased. Symptoms improved in 12 (57%), worsened in 3 (14%), and mixed in 5 (24%). When symptoms improved, the same dose was present in 7/12 (58%) and dose decreased in 3 (25%). 51 subjects were diagnosed with depression. 32 (63%) had no change in therapy, 11 (21%) discontinued, and 4 (8%) decreased. Symptoms improved in 34 (67%), mixed in 10 (20%), worsened in 4 (8%), and unchanged in 3 (6%). When symptoms improved, the same regimen and dose was present in 21/34 cases (62%) and discontinued in 9 (26%). Conclusion. Anxiety symptoms improved in >50% of subjects at predominantly the same or reduced dosage. Depression symptoms improved in 67% and commonly without therapy change. These data suggest evidence that patients undergoing SG while on medication for anxiety or depression may have early symptom improvement on the same or lessened dosage.
