Hidradenitis suppurativa affects a significant portion of the population and has numerous treatment options. However, these options often come with side effects. Exercise, weight loss, and dietary modifications may offer simple and inexpensive alternatives or adjuncts to treatment. This study aimed to summarize the evidence on the effects of these interventions and provide guidance for clinicians on dietary changes and exercise modalities.
BackgroundHidradenitis suppurativa affects up to 4% of the population worldwide. Many treatment options exist but these come with a significant side-effect profile. Exercise, weight loss, and dietary modifications may be simple inexpensive alternatives and/or adjuncts to treating this disease.ObjectivesWe aimed to summarize published evidence on the effects of dietary, weight loss, and exercise interventions on the clinical course, severity, or subjective improvement of hidradenitis suppurativa and to provide a framework regarding dietary changes and exercise modalities for clinicians treating this disease.MethodsA literature search of Scopus (1993 onwards), PubMed (1986 onwards), and MEDLINE (OVID interface, 1946 onwards) was conducted on 22 October, 2022. Case-control studies, cohort studies, and randomized controlled trials with five or more subjects conducted on adult participants (aged >18 years) were included; case reports, case series, and review papers were excluded.ResultsFifteen studies involving 2829 patients were included, encompassing nine cohort studies, five cross-sectional studies, and one cross-over study. Patients who were female, lost more than 50 pounds (22.7 kg), or were obese prior to weight loss saw improvement in hidradenitis suppurativa severity with weight loss. There was evidence for beneficial effects of diets, such as the Mediterranean diet that minimizes sugar, highly processed carbohydrates, and dairy, and emphasizes chicken, fruits, and vegetables, in patients with hidradenitis suppurativa. Evidence also supported benefit from oral zinc and vitamin D supplementation.ConclusionsMore evidence is needed in the form of randomized controlled trials or well-designed controlled trials to evaluate the effect of exercise and dietary manipulation on the hidradenitis suppurativa disease course. Overall, there is significant but weak evidence to support improvement in hidradenitis suppurativa severity with weight loss, dietary changes, and micronutrient supplementation. There is no significant evidence to support improvement in hidradenitis suppurativa symptomology with any type of exercise intervention.
