HS Linked to Increased Risk for Eating Disorders

Individuals with hidradenitis suppurativa (HS) face a significantly increased risk for bulimia nervosa and binge eating disorder, an analysis of national data showed.

“Clinicians should actively screen for eating disorders,” particularly bulimia nervosa and binge eating disorder, in patients with HS,” lead study author Christopher Guirguis, DMD, a student at Georgetown University School of Medicine, Washington, DC, told this news organization in advance of the annual Symposium on Hidradenitis Suppurative Advances, where the study was presented during an oral abstract session. “The significant psychological burden in these patients requires a holistic approach that integrates both dermatologic and psychosocial care. Addressing their mental health needs is essential for improving overall patient outcomes and quality of life,” he added.

In collaboration with fellow Georgetown medical student and first author Lauren Chin and Mikael Horissian, MD, a dermatologist and director of the HS Clinic at Gesinger Health System, Danville, Pennsylvania, Guirguis drew from the National Institutes of Health’s All of Us Research Program to identify 1653 individuals with a diagnosis of HS and a control group of 8265 individuals without a diagnosis of HS. They used the Observational Medical Outcomes Partnership to identify anorexia nervosa, bulimia nervosa, body dysmorphic disorder, binge eating disorder, and eating disorder, unspecified. Obsessive-compulsive disorder (OCD) was also included because of its association with bulimia. They used statistical models to compare cohorts and comorbidities. “What makes this work unique is its focus on the link between HS and eating disorders, a relationship previously underexplored,” he said.

The mean age of the overall study cohort was 46.8 years, and 78.6% were female. Univariate analysis revealed that, compared with controls, individuals in the HS cohort showed significantly increased diagnoses of bulimia, binge eating disorder, OCD, and eating disorder, unspecified, by 2.6, 5.48, 2.50, and 2.43 times, respectively (P P 

Guirguis said that the absence of body dysmorphic disorder diagnoses in the HS cohort was unexpected. “Given HS’s known association with body image issues, we anticipated a higher prevalence of BDD,” he said. “This discrepancy may reflect underreporting or diagnostic overshadowing, where the physical symptoms of HS dominate clinical attention, potentially masking or complicating the identification of psychological conditions like BDD.”

He acknowledged certain limitations of the study, including the potential for variations in documentation practices in the database. “Additionally, there may be bias due to underrepresentation of certain demographic groups or underreporting of psychological comorbidities, which could influence the findings.”

Patricia M. Richey, MD, assistant professor of dermatology, at Boston University School of Medicine, Boston, Massachusetts, who was asked to comment on the study, said the results “should affect how physicians discuss lifestyle recommendations in those already at increased risk of psychiatric disease and disrupted body image.” The findings should also “prompt physicians to screen this patient population more thoroughly for eating disorders as we know they are an underrecognized and often undertreated entity,” she added.

Neither the study authors nor Richey reported having relevant disclosures.
