Definition
Hidradenitis suppurativa (HS) is long term, recurring condition of the hair follicle. Inflamed nodes and cysts form in the armpits and groin. These may also be found under the breasts, and around the nipples, and anus. Other areas may be affected, but this isn’t common.
Causes
The hair follicle becomes blocked causing inflammation. This may lead to abscesses, infection, or scars. The sweat glands may also become inflamed.
A mix of factors lead to HS such as:
- Genetics
- An overactive immune system
- How hormones act on the body
Risk Factors
HS is more common in women than in men. Your chances of HS are also higher if you:
- Have a family history
- Smoke —present or past
- Are overweight
- Have diabetes
- Have metabolic syndrome —marked by raised blood pressure, cholesterol, blood glucose, and body weight
- Have problems with cholesterol
Symptoms
Most people with HS have problems after adolescence. But HS can happen at any age. HS may cause:
- Burning, itching, or painful lumps in the armpits, groin, under the breasts, around the nipples or anus, and other involved areas
- Pus leaking from breaks in the lumps
- Scarring
Diagnosis
The doctor will ask about your symptoms and health history. Your answers and a physical exam may point to HS. In some cases, you may have blood tests or swabs of the fluid from your skin.
