Abstract

Background

The veteran population is routinely screened for post-traumatic stress disorder (PTSD). The prevalence of obesity in this population continues to increase. We examined whether weight loss outcomes in veterans with PTSD is comparable to results in veterans who do not suffer from PTSD, after gastric bypass. We also examined the effect of bariatric surgery on PTSD symptoms.

Methods

This retrospective review of prospective data compares veterans with and without PTSD who underwent laparoscopic gastric bypass. Differences between the means of age, initial BMI, and percent excess weight loss were compared between the groups using a Student’s t test. Pearson’s χ2 was used to evaluate the relationship between a diagnosis of PTSD, major depressive disorder (MDD), and other Axis I psychiatric disorders. A similar analysis was done to assess for a relationship between PTSD and obesity-related comorbidities, including diabetes mellitus (DM), hypertension (HTN), hyperlipidemia, and GERD.

Results

We identified 24 patients who had gastric bypass and a diagnosis of PTSD before surgery and compared them to those without PTSD. Both groups had a similar mean age and initial BMI. There was no significant difference between the percent excess weight lost after 1 year follow-up between the PTSD group (66%) and the non-PTSD group (72%) (p = 0.102). In assessing comorbid conditions, we found a significant association between the diagnosis of PTSD and MDD (p = 0.002), PTSD and other Axis I disorders (p = 0.004), and PTSD and GERD (p = 0.002). However, we saw no significant association between PTSD and DM (p = 0.977), HTN (p = 0.332), and obstructive sleep apnea (OSA) (p = 0.676). The severity of PTSD symptoms fluctuated in the postoperative period.

Conclusions

Veterans with PTSD have comparable weight loss to those without PTSD after gastric bypass. In addition, surgery does not seem to have an adverse effect on PTSD symptoms, although PTSD symptomatology tends to fluctuate over time. Further study in this patient population is warranted.
