>> What areas of the body are affected by hidradenitis suppurativa?

The areas of the body that are most severely affected by HS are those that contain a high number of apocrine glands (see ‘What causes HS?’). These are:

  • armpits (axillae)
  • groin
  • genitals
  • pubic area
  • anal area (perianal region)
  • buttocks
  • underneath the breasts
  • upper thighs.

If none of the above areas has been affected, it is unlikely that you have HS. However, it is possible for HS to occur in other areas of the body. It is unlikely that you will be affected in all these areas at the same time. Some areas may be quite inflamed while other areas are quiet.
Women seem to be more commonly affected in the groin region than men.1
