Hidradenitis suppurativa (HS), also known as acne inversa, is a chronic skin condition characterized by the formation of small, painful lumps beneath the skin. These lumps typically occur in areas where skin rubs together, such as the armpits, groin, buttocks, and under the breasts. The bumps associated with HS can be slow to heal, tend to recur, and may lead to the development of tunnels under the skin and subsequent scarring.
HS usually emerges after puberty and before the age of 40, often persisting for many years and potentially worsening over time. This condition can significantly impact daily life and emotional well-being. However, a combination of medical and surgical treatments can effectively manage HS and help prevent complications.
It’s worth noting that women are diagnosed with hidradenitis suppurativa approximately three times more often than men, although this ratio can vary globally. Furthermore, individuals of Black ethnicity have a higher predisposition to developing HS compared to other racial groups, which may be partly attributed to genetic factors.

Symptoms of HS
Hidradenitis suppurativa can manifest in one or multiple areas of the body. The signs and symptoms of HS include:
- Blackheads. These appear in small, pitted regions of skin and often present in pairs, a distinctive characteristic of hidradenitis suppurativa.
- Painful, Pea-sized Lumps. HS often begins with a single, tender lump beneath the skin that can persist for weeks or even months. Subsequently, more bumps may develop, typically in areas with a higher concentration of sweat and oil glands, or where skin surfaces rub against each other, such as the armpits, groin, buttocks, and breasts. These painful lumps are a primary symptom of hidradenitis suppurativa.
- Leaking Bumps or Sores. Some of these bumps or sores can enlarge, rupture, and discharge pus, often accompanied by a noticeable odor. This drainage is a common feature of HS lesions.
- Tunnels. Over time, in more advanced hidradenitis suppurativa, tunnels may form beneath the skin, connecting the lumps. These wounds are slow to heal, or may not heal at all, and can drain blood and pus, representing a significant complication of HS.
The severity of hidradenitis suppurativa symptoms can vary significantly from person to person. Some individuals may only experience mild symptoms, while others face a more severe and debilitating course of the disease. Factors such as excess weight and smoking are associated with a worsening of HS symptoms, but it’s important to note that even individuals who are lean and do not smoke can still develop severe hidradenitis suppurativa.
When to Seek Medical Advice for HS
Early diagnosis of hidradenitis suppurativa is crucial for effective management and treatment. It’s important to consult a dermatologist if you experience any of the following related to a potential HS condition:
- Pain: If the condition is causing you pain and discomfort.
- Limited Mobility: If HS makes it difficult to move or restricts your range of motion.
- Non-improving Condition: If your symptoms do not improve within a few weeks.
- Recurrent Issues: If the condition returns within weeks after previous treatment.
- Multiple Locations: If the bumps or sores appear in several different areas of your body.
- Frequent Flare-ups: If you experience frequent flare-ups of the condition.
A dermatologist specializing in skin conditions can provide an accurate diagnosis of hidradenitis suppurativa and develop an appropriate treatment plan tailored to your specific needs.
It’s essential to understand that hidradenitis suppurativa is more than just a boil. Many individuals with HS may also have other related health conditions. Therefore, a comprehensive healthcare team, led by medical and surgical dermatologists, is often beneficial in managing hidradenitis suppurativa effectively. Other specialists may be involved as needed to address the various aspects of this complex condition.
Causes of Hidradenitis Suppurativa
The exact cause of hidradenitis suppurativa is not fully understood. However, HS develops when hair follicles become blocked. The reason for this blockage is still under investigation, but experts believe several factors may be involved, including:
- Hormones: Hormonal fluctuations and imbalances may play a role in the development of hidradenitis suppurativa.
- Genetic Predisposition: Genetics may increase susceptibility to HS, as a family history of the condition is a known risk factor.
- Cigarette Smoking: Smoking is considered a contributing factor that can exacerbate HS.
- Excess Weight: Being overweight or obese is associated with a higher risk of developing and worsening hidradenitis suppurativa.
It is important to emphasize that hidradenitis suppurativa is not caused by infection or poor hygiene, and it is not contagious. HS cannot be spread from person to person.
Risk Factors for HS
Several factors can increase the likelihood of developing hidradenitis suppurativa:
- Age: The risk of HS is highest for individuals in their teens and 20s.
- Sex: Women are more prone to developing hidradenitis suppurativa than men.
- Race/Ethnicity: Race and ethnicity can influence HS risk. It is observed more frequently in Black individuals, potentially due to genetic factors.
- Family History: A family history of hidradenitis suppurativa significantly increases the risk of developing the condition, indicating a genetic component to HS.
- Certain Medical Conditions: Hidradenitis suppurativa is more prevalent and tends to be more severe in individuals who are overweight or obese. It’s also linked to other conditions like severe acne, arthritis, diabetes, metabolic syndrome, and inflammatory bowel disease.
- Smoking: Tobacco smoking is strongly associated with an increased risk of hidradenitis suppurativa.
Complications of HS
Persistent and severe hidradenitis suppurativa can lead to various complications, including:
- Infection: While pus is common in HS and not always indicative of infection, secondary bacterial infections can occur in the affected areas.
- Scarring and Skin Changes: HS wounds can heal but often leave behind ropelike scars or pitted skin, which can be disfiguring and cause ongoing discomfort.
- Restricted Movement: Sores and scar tissue, particularly when HS affects the armpits or thighs, can restrict movement and cause pain, impacting daily activities.
- Skin Cancer: In cases of long-term hidradenitis suppurativa, especially when involving the perianal area (tissues around the anus), there is an increased risk of squamous cell carcinoma, a type of skin cancer.
- Swelling (Lymphedema): Common HS sites contain numerous lymph nodes. Scar tissue can disrupt the lymphatic drainage system, potentially leading to swelling in the arms, legs, or genitals.
- Psychological Effects and Social Isolation: The location, drainage, and odor associated with HS sores can cause significant embarrassment and self-consciousness, leading to reluctance to socialize and potentially resulting in anxiety or depression.
- Chronic Pain: Hidradenitis suppurativa can cause lifelong pain that can be more severe and debilitating than conditions like psoriasis, significantly impacting quality of life.
Understanding “What Is Hs” is the first step in managing this condition. If you suspect you may have hidradenitis suppurativa, seeking early medical advice from a dermatologist is crucial for proper diagnosis and the initiation of effective treatment strategies to manage symptoms and prevent complications.
