What is HS?1

Hidradenitis Suppurativa (HS) is a chronic skin condition that is expressed through repeated painful inflamed nodules or abscesses localized at the level of the skin folds. HS is sometimes referred to as ‘Acne Inversa’ or ‘Verneuil’s disease’.

HS is most common in the armpits and groin area, but can also occur under the breasts, in skin folds of the abdomen, as well as around the buttocks, genitals and anus. HS usually starts after puberty and three-quarters of patients are women. Studies have shown that 1%-2% of the adult population suffers from HS to varying degrees.
