WHO?

  • Studies have reported a global prevalence of 1% in the general population.1
  • The condition is easy to misdiagnose and because people living with HS often feel too embarrassed to talk about their symptoms or to seek medical help from their GP, the number of people who are actually diagnosed with HS is far less than this estimate.2,3
  • HS can occur at any age, but the condition most commonly develops in adults in their early 20s and declines after the age of 50-55.2,3
  • Women are more likely to develop HS than men.2,3

WHAT?

  • Hidradenitis suppurativa, also known as HS, is a long-term or chronic skin condition that can be distinguished by painful, inflamed areas typically located around the armpits, groin and in between the buttocks. The inflamed pustules, nodules and spots usually occur where certain sweat glands (known as apocrine glands) are located, as well as under the breasts and on the inner thighs, where skin may rub together.1,2,3,4,5

WHERE?

  • Hidradenitis suppurativa typically affects areas on the body:
    • With apocrine glands (sweat glands in areas with abundant hair follicles) such as the armpits and groin2,3,4,5
    • Where the skin rubs together, such as under the breasts, in between the buttock ,and on the inner thighs3,4,5

WHY?

  • Scientists don't know exactly what causes hidradenitis suppurativa or HS, but problems with the structure of the hair follicle are thought to play a role.3,7
  • It is also thought that the inflamed spots and pustules tend to develop when there is a blockage of hair follicles and inflammation of certain sweat glands found in certain areas like the armpits and groin.3,4,5
  • Blockage of the hair follicle can cause the area to swell up and burst, or may form abscesses and become severely infected.4,7
