Key Takeaways

This chronic inflammatory condition affects 1-4% of the population, predominantly women aged 20-40, causing painful nodules in areas with apocrine sweat glands like armpits, groin, and under breasts.
The condition progresses through three Hurley stages: Stage I involves isolated nodules, Stage II creates sinus tracts and scarring, while Stage III forms interconnected tunnels and extensive scarring across entire regions.
Unlike typical acne, lesions develop deep under the skin and can persist for weeks to months, often rupturing and draining foul-smelling pus before healing with rope-like scars.
TNF-alpha inhibitors like adalimumab (Humira) are FDA-approved biologics that can reduce flare frequency by 50% in moderate to severe cases, though they require ongoing injections every other week.
Surgical intervention becomes necessary in advanced stages, with wide excision removing all affected tissue—healing can take 2-6 weeks, but recurrence rates drop significantly compared to medical therapy alone.

Hidradenitis suppurativa (HS), also known as acne inversa, is a chronic inflammatory skin condition that causes painful bumps to form under the skin near hair follicles and sweat glands. These bumps can become infected, leading to pockets of pus that may emit an unpleasant odor when they rupture. HS is not contagious and is not caused by poor hygiene.

Causes of Hidradenitis Suppurativa

The exact cause of HS is unknown, but it is believed to be a combination of genetic, hormonal, and environmental factors. The condition often begins when hair follicles become blocked. Risk factors for developing HS include:

Being female
Having a family history of HS
Being overweight or obese
Smoking
Having a history of acne

Symptoms and Common Sites of Hidradenitis Suppurativa

HS typically affects both sides of the body in areas where hair grows or skin rubs together, such as:

Armpits
Groin
Between the buttocks
Under the breasts
Inner thighs

Symptoms may include painful, inflamed bumps that can last for days or months, as well as itching, blackheads, and tunnels (sinus tracts) connecting the bumps under the skin.

Stages of Hidradenitis Suppurativa

HS is divided into three stages based on severity:

Hurley stage I: Single or multiple isolated bumps with no sinus tracts
Hurley stage II: Multiple bumps with some sinus tracts and scarring
Hurley stage III: Multiple bumps with extensive sinus tracts and scarring involving an entire area of the body

Diagnosing Hidradenitis Suppurativa

A doctor can diagnose HS based on the appearance and location of the bumps and how often they occur. They may ask about the duration and severity of symptoms, as well as family history. In some cases, a sample of pus may be taken for lab testing to rule out other infections.

Treatment Options for Hidradenitis Suppurativa

While there is no cure for HS, various treatments can help manage symptoms and prevent flare-ups. Treatment depends on the severity of the condition and may include:

Warm compresses
Over-the-counter pain relievers (NSAIDs)
Antibiotics
Corticosteroid injections
Oral retinoids
Hormonal therapy
Biologics
Surgery

Your doctor will work with you to develop an individualized treatment plan based on your specific needs and the severity of your HS.

Lifestyle Changes to Manage Hidradenitis Suppurativa

In addition to medical treatments, certain lifestyle changes can help manage HS and reduce flare-ups:

Losing excess weight
Quitting smoking
Avoiding shaving affected areas
Wearing loose-fitting clothing
Staying cool to minimize sweating
Gently cleansing affected areas daily
Using appropriate bandages for draining bumps

Some people with HS may also benefit from dietary changes, such as following a Mediterranean diet, a plant-based diet, or reducing sugar and dairy intake. However, it is essential to consult with a doctor before making significant dietary changes.

Coping with Hidradenitis Suppurativa

Living with HS can be challenging, both physically and emotionally. It is essential to seek support from trusted friends, family, or a professional counselor. Joining a support group can also provide a safe space to connect with others who understand your experiences.

Outlook and Takeaways

Although hidradenitis suppurativa is a chronic condition that may require long-term management, early diagnosis and appropriate treatment can significantly improve symptoms and quality of life. By working closely with a healthcare provider and making necessary lifestyle changes, people with HS can lead normal, fulfilling lives.

The Bottom Line

Early recognition and treatment are crucial since this progressive condition worsens over time without proper management, and biologics work best before extensive scarring develops. Weight loss, smoking cessation, and loose-fitting clothes help prevent flares, but medical treatment is essential for long-term control. If you're experiencing recurring painful bumps in skin fold areas, Doctronic can help you get a proper evaluation and treatment plan.
