What Is Hidradenitis Suppurativa (HS)?
Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition causing cysts, abscesses, sinus tracts, and scarring. It primarily presents beneath the arms, in the groin or buttock areas, or underneath the breasts. However, it can also occur elsewhere. HS is twice as common in females as in males, and typically presents between puberty and age 40. Several factors contribute to the development and worsening of HS, including:
Approximately 40% of people with HS have a first-degree family member with the skin condition as well. HS is more common in overweight or obese persons; however, it is not limited only to them. The majority of HS patients are smokers, and smokers are typically found to have more severe disease than non-smokers. Hormones are thought to play a role in HS because it is typically only seen post-puberty.
