Hidradenitis Suppurativa and Obesity
Hidradenitis suppurativa is a chronic inflammatory skin condition with painful lumps and boils, and obesity makes it more likely and more severe.
Plain English
Patient-Friendly Explanation
Hidradenitis suppurativa is a long-term skin condition that causes painful, recurring lumps and boils, usually in areas where skin rubs together such as the armpits, groin and under the breasts. It is much more common in people living with obesity, and excess weight tends to make it more severe and harder to control. Losing weight can reduce flare-ups and is an important part of managing the condition.
Medical
Clinical Definition
Hidradenitis suppurativa (HS) is a chronic, inflammatory dermatosis of follicular occlusion affecting intertriginous skin bearing apocrine glands, characterised by recurrent nodules, abscesses, sinus tracts and scarring. Obesity is among the strongest modifiable risk factors: HS prevalence and severity increase with body mass index, and mechanisms include mechanical friction, occlusion and the systemic pro-inflammatory and hyperinsulinaemic state of adiposity. Weight loss, including after bariatric surgery, is associated with meaningful improvement in HS disease activity, and the condition itself is an independent marker of cardiovascular and metabolic comorbidity.
Key Insight
Why It Matters
Hidradenitis suppurativa is a genuine medical condition, not a hygiene problem — and many patients are relieved to hear it has real treatments. Because weight is one of the strongest drivers, weight management is a legitimate part of calming the disease.
