Bariatric Surgery Reduces Depression, Night Eating in Patients with NES
Bariatric surgery helps reduce depressive symptoms and improve night eating in patients with night eating syndrome (NES), according to a recent study.
Most previous studies have shown an association between obesity, depressive mood, and NES. However, little information exists regarding the impact of bariatric surgery on NES, particularly in patients with depressive symptoms.

In their study, the researchers evaluated 60 participants who consecutively consented to receive bariatric surgery. A total of 51 participants were women. Mean age of participants was 34.7 years, and mean body mass index was 46.04.
The Beck Depression Inventory-Short Form (BDI-SF) was used to assess depressive symptoms, and the Night Eating Questionnaire was used to assess night eating.
Results of the study indicated that BDI-SF scores had improved after bariatric surgery. Night Eating Questionnaire scores among participants with baseline depressive symptoms improved significantly compared with participants without depressive symptoms, despite a similar post-operative reduction in weight across groups.
“Bariatric surgery is associated with a reduction in depressive symptoms,” the researchers concluded. “After the surgical intervention, improvement of night eating can be observed predominantly in patients with preoperative depressive symptoms. These findings are consistent with the hypothesis of an important role of mood problems in NES.”
