Obesity in Hidradenitis Suppurativa: Are GLP-1 Receptor Agonists the New Frontier?

Abstract

Hidradenitis suppurativa (HS) is an inflammatory skin disorder presenting with painful and draining nodules in intertriginous areas that may progress to sinus tracts. There is an increased prevalence of obesity in HS, and obesity may predispose patients to HS. Weight loss has been associated with improvement of HS symptoms. However, weight loss through diet modification, exercise or bariatric surgery has mixed results. Recently, glucagon-like peptide-1 (GLP-1) receptor agonists have been investigated for weight loss in HS. These drugs are effective for weight loss and reduce weight-related comorbidities, with few significant side effects. Early studies of liraglutide and semaglutide in HS have demonstrated improvement in disease severity and quality of life. GLP-1 receptor agonists are a promising therapy for patients with HS and may improve symptoms through decreased mechanical stress and moderation of inflammation.
