Original Article



Obesity is a multifactorial disease characterized by genetic, social, cultural and psychological factors. Currently, bariatric surgery represents the gold-standard intervention to treat morbid obesity in order to counteract associated disabling comorbidities. Several studies showed correlation between post-surgery weight loss and psychological factors. Also, the alexithymia may have a role in affecting post-surgery outcomes in bariatric patients, even if there are no studies investigating its role at 12-month follow-up. The purpose of the present study was to investigate the association between alexithymia and the postoperative weight loss 12 months after laparoscopic sleeve gastrectomy.


Seventy-five patients undergoing laparoscopic sleeve gastrectomy were enrolled. The Toronto Alexithymia Scale (TAS-20) was administered to patients. A postoperative weight loss check was performed at 3 and then 12 months after surgery.


The TAS-20 total score was negatively correlated with the percent of excess weight loss (%EWL) at the 12-month follow-up (r = −0.24; p = 0.040). The analysis showed that non-alexithymic patients had a greater weight loss at 12 months after surgery compared to both probably alexithymics (71.88 ± 18.21 vs. 60.7 ± 12.5; p = 0.047) and probably alexithymic patients (71.88 ± 18.21 vs. 56 ± 22.8; p = 0.007). The preoperative BMI was a significant covariate [F(1,70) = 6.13 (p = 0.016)].


In the present study, the patients with higher preoperative BMI and identified as alexithymic showed lower %EWL at 12 months after laparoscopic sleeve gastrectomy. Findings point out the importance to take into consideration possible psychological treatments focused on improving emotional regulations of patients who are seeking bariatric surgery.
