Smoking Cessation Is CrucialSmoking is strongly linked to hidradenitis suppurativa severity and progression — quitting smoking is one of the most impactful things a patient can do to improve their condition.
Is hidradenitis suppurativa contagious?
No — it's not an infection that can be spread to others, though secondary bacterial infection of the lesions can occur.
Is hidradenitis suppurativa the same as acne?
No — though related in some ways, HS is a distinct chronic inflammatory condition affecting hair follicles in specific body areas, requiring different treatment approaches than typical acne.
