Causes & Risk Factors

Several factors can contribute to Hidradenitis Suppurativa.

The exact cause of hidradenitis suppurativa involves a combination of factors that create the perfect storm for chronic inflammation.

The exact cause of hidradenitis suppurativa involves a combination of factors that create the perfect storm for chronic inflammation. At its core, HS begins when hair follicles in areas rich with apocrine sweat glands become blocked and inflamed. Think of it like a clogged drain that backs up - but instead of water, inflammatory cells and bacteria accumulate, creating painful abscesses that can rupture and form connecting tunnels under the skin.

Genetics play a significant role, with roughly one-third of people with HS having a family member who also has the condition.

Genetics play a significant role, with roughly one-third of people with HS having a family member who also has the condition. Scientists have identified several gene mutations that affect how the immune system responds to blocked follicles, making some people more prone to the intense inflammatory reaction that characterizes HS. These genetic variations don't guarantee someone will develop the condition, but they set the stage for it when other triggers are present.

Hormonal fluctuations act as a major trigger, explaining why HS often begins after puberty and why women are more frequently affected.

Hormonal fluctuations act as a major trigger, explaining why HS often begins after puberty and why women are more frequently affected. Androgens (male hormones present in both sexes) stimulate the apocrine glands, while estrogen fluctuations during menstrual cycles, pregnancy, or menopause can worsen symptoms. Environmental factors like friction from tight clothing, obesity, smoking, and stress can all contribute to flare-ups by increasing inflammation or creating conditions that favor bacterial growth in affected areas.

Risk Factors

Family history of hidradenitis suppurativa
Being female, especially during reproductive years
Obesity or being significantly overweight
Smoking cigarettes or using tobacco products

Diagnosis

How healthcare professionals diagnose Hidradenitis Suppurativa:

1
Diagnosing hidradenitis suppurativa relies primarily on recognizing its distinctive pattern and appearance, as no single test can definitively identify the condition.
Diagnosing hidradenitis suppurativa relies primarily on recognizing its distinctive pattern and appearance, as no single test can definitively identify the condition. Your doctor will examine the affected areas and ask detailed questions about when symptoms started, how they've progressed, and whether family members have similar issues. The diagnosis becomes clearer when painful lumps appear in characteristic locations like armpits, groin, or under breasts, especially if they recur in the same spots or create connecting tunnels under the skin.

Since HS can mimic other conditions, your healthcare provider may order tests to rule out alternatives.
Since HS can mimic other conditions, your healthcare provider may order tests to rule out alternatives. Blood tests can check for signs of infection or inflammation, while bacterial cultures from draining lesions help identify any secondary infections that need treatment. In some cases, an ultrasound or MRI might reveal the extent of tunneling beneath the skin, which helps determine the stage of disease and guide treatment decisions.

The process often involves seeing a dermatologist who specializes in inflammatory skin conditions, as HS can be mistaken for recurring boils, ingrown hairs, or even sexually transmitted infections.
The process often involves seeing a dermatologist who specializes in inflammatory skin conditions, as HS can be mistaken for recurring boils, ingrown hairs, or even sexually transmitted infections. Getting an accurate diagnosis sometimes takes time, with studies showing many people wait an average of 7 years before receiving proper identification of their condition. Key features doctors look for include: recurring painful lumps in skin-fold areas, blackheads in double or triple patterns, tunneling or scarring between lesions, and symptoms that persist or worsen over time.

Complications

Hidradenitis suppurativa can lead to several complications that extend beyond the initial skin inflammation, making early and aggressive treatment valuable for preventing long-term problems.
The most common complication is extensive scarring and the formation of sinus tracts - tunnel-like connections between different affected areas that can persist even when active inflammation subsides.
These scars can restrict movement, particularly in areas like the armpits or groin, and may require surgical correction to restore full mobility.
More serious complications can develop when the condition remains untreated or poorly controlled over many years.
Secondary bacterial infections can spread to surrounding tissues, occasionally requiring hospitalization for intravenous antibiotics.
In rare cases, chronic inflammation can lead to the development of squamous cell carcinoma, a type of skin cancer that can occur in long-standing HS lesions.
People with severe HS also face increased risks of depression, anxiety, and social isolation due to pain, odor, and the visible nature of the condition.
However, with proper medical care and support, most complications can be prevented or successfully managed, allowing people with HS to maintain active, fulfilling lives.

Prevention

While hidradenitis suppurativa cannot be completely prevented due to its genetic component, several strategies can significantly reduce the risk of flare-ups and slow disease progression.
The most impactful change is maintaining a healthy weight, as excess body weight increases friction and pressure in skin-fold areas where HS typically develops.
Regular exercise and a balanced diet not only help with weight management but also reduce overall inflammation in the body.
Daily habits make a substantial difference in managing symptoms and preventing new lesions.
Choose loose-fitting, breathable clothing made from natural fibers like cotton to minimize friction and allow air circulation.
Use gentle, fragrance-free cleansers rather than harsh soaps or scrubs that can irritate sensitive skin.
Quit smoking if you currently use tobacco - studies show smokers with HS experience more severe symptoms and respond less well to treatments.
Managing stress through meditation, regular sleep, or counseling can help prevent stress-triggered flare-ups.
Some people find that certain foods seem to trigger their symptoms, though dietary connections vary from person to person.
Common culprits include dairy products, foods high in refined sugar, or brewer's yeast.
Keeping a food and symptom diary can help identify personal triggers.
While these prevention strategies cannot guarantee you'll avoid HS entirely, they can significantly improve quality of life and reduce the frequency and severity of flare-ups for those already living with the condition.

Treatment Approaches

Treatment for hidradenitis suppurativa focuses on reducing inflammation, preventing new lesions, and managing existing symptoms through a combination of approaches tailored to disease severity.

Treatment for hidradenitis suppurativa focuses on reducing inflammation, preventing new lesions, and managing existing symptoms through a combination of approaches tailored to disease severity. For mild cases, topical antibiotics like clindamycin can help control bacterial growth, while warm compresses and gentle cleansing with antibacterial soaps provide daily relief. Many people find that zinc supplements and anti-inflammatory medications help reduce the frequency and intensity of flare-ups.

Moderate to severe HS often requires systemic treatments that work throughout the body.

Moderate to severe HS often requires systemic treatments that work throughout the body. Oral antibiotics such as tetracycline, doxycycline, or clindamycin combined with rifampin can control inflammation and infection for weeks or months at a time. For more stubborn cases, doctors may prescribe immunosuppressive medications like methotrexate or cyclosporine, or biologics such as adalimumab (Humira), which specifically target the inflammatory pathways involved in HS.

Surgical options become necessary when medical treatments aren't sufficient or when extensive scarring and tunneling have developed. Procedures range from simple drainage of individual abscesses to wide excision of affected tissue followed by skin grafts. Laser therapy shows promise for destroying hair follicles and reducing inflammation, while newer treatments like carbon dioxide laser therapy can help close persistent tunnels. Some patients benefit from intralesional steroid injections during acute flare-ups to quickly reduce pain and swelling.

Frequently Asked Questions

Is hidradenitis suppurativa contagious?

No, HS is not contagious and cannot be spread through contact, sharing personal items, or any other means. It's an inflammatory condition caused by genetics and immune system factors, not an infection that can be transmitted to others.

Will hidradenitis suppurativa ever go away completely?

HS is typically a chronic condition that requires long-term management rather than a cure. However, with proper treatment, many people experience long periods of remission with minimal or no symptoms. Some people do see significant improvement or even complete clearing with effective treatment.

Can I still exercise and play sports with HS?

Yes, but you may need to modify activities based on your symptoms and affected areas. Low-impact exercises like swimming, walking, or yoga are often well-tolerated. Choose moisture-wicking clothing and shower immediately after exercising to prevent irritation.

How does pregnancy affect hidradenitis suppurativa?

Pregnancy affects HS differently for different women. Some experience improvement due to hormonal changes, while others may see worsening symptoms. Many HS medications need to be adjusted during pregnancy, so close coordination with your healthcare team is essential.

Are there foods I should avoid if I have HS?

While research is ongoing, some people report improvements when avoiding dairy products, refined sugars, or brewer's yeast. There's no universal HS diet, but keeping a food diary can help you identify personal triggers. Work with your doctor before making major dietary changes.

Can children develop hidradenitis suppurativa?

HS rarely appears before puberty, as it requires activation of apocrine sweat glands by hormones. When it does occur in children, it's usually after they begin puberty and may be more likely in those with a strong family history of the condition.

Will losing weight cure my hidradenitis suppurativa?

Weight loss alone won't cure HS, but it can significantly improve symptoms by reducing friction and pressure in affected areas. Many people see fewer flare-ups and better response to treatments after achieving a healthier weight.

How do I find a doctor who understands HS?

Start with a dermatologist, preferably one who specializes in inflammatory skin conditions or mentions HS experience. Patient advocacy organizations often maintain lists of HS-knowledgeable physicians. Don't hesitate to seek a second opinion if you feel your concerns aren't being addressed.

Can hidradenitis suppurativa affect my ability to work?

Many people with HS work successfully, though some may need workplace accommodations during flare-ups. This might include flexible scheduling, the ability to work from home during severe episodes, or ergonomic adjustments. Severe cases may qualify for disability benefits.

What's the difference between HS and regular boils or abscesses?

HS lesions typically recur in the same locations, occur in characteristic areas like armpits and groin, and often create connecting tunnels under the skin. Regular boils are usually isolated incidents that heal completely and don't form the scarring patterns seen in HS.
