Hidradenitis suppurativa is a skin condition that causes swelling. Lumps form on the surface that eventually become boils. If a boil ruptures, the fluid they contained can result in infections if it comes into contact with broken skin. In most cases, hidradenitis suppurativa is caused by issues with the sweat glands and hair follicles.
Experts do not know exactly why people develop hidradenitis suppurativa (HS), though most presume a relationship between the condition and the sweat glands and hair follicles. They have identified some risk factors that make it more likely for someone to develop HS. The condition is most common in young adults between the ages of 18 and 29, and affects more women than men. Other risk factors include obesity, smoking, and the presence of a family history of hidradenitis suppurativa.
