Association of Body Dysmorphic Disorder with Leptin Levels in Patients with Normal Weight Undergoing Liposuction: A Matched Case Study.

BACKGROUND

Liposuction is the most common aesthetic surgical procedure performed globally. Some of the patients with normal weight who seek liposuction may suffer from body dysmorphic disorder (BDD). Leptin, which is mainly produced by adipose tissue, may be associated with this condition. The aim of this study was to determine the prevalence of BDD and leptin levels in patients with normal weight seeking liposuction.

METHODS

Thirty-two nonobese women who sought liposuction were matched with 32 healthy volunteers by age and body mass index. Blood biochemistry, leptin levels, and BDD-Yale-Brown Obsessive-Compulsive Scale (BDD-YBOCS) questionnaires were evaluated and compared between the groups.

RESULTS

Patients who underwent liposuction had significantly higher median (interquartile range) of total BDD-YBOCS scores than healthy volunteers [25 (22-27) versus 12 (8-20); P < 0.001]. Overall, 28 (87.5%) patients had total BDD-YBOCS scores of >20, whereas 10 (31.5%) volunteers had scores of >20. Patients with total BDD-YBOCS scores of >20 had significantly lower levels of serum leptin [12.43 (7.15-16.98) ng/ml versus 15.57 (9.59-22.28) ng/ml; P = 0.043].

CONCLUSIONS

Patients who underwent liposuction had a significantly higher total score of BDD-YBOCS than healthy volunteers matched by sex, age, and body mass index. Subjects with higher BDD-YBOCS scores had significantly lower serum leptin levels.
