What is Hidradenitis Suppurativa?

Hidradenitis suppurativa is a long-term inflammatory disease that affects hair follicles. It causes painful lumps, boils, abscesses and sometimes tunnel-like tracts beneath the skin.

HS most commonly occurs in the armpits, groin, buttocks, inner thighs and under the breasts. The condition is not contagious and is a result of poor hygiene. Although the exact cause is not fully understood, blocked hair follicles and an abnormal immune response are believed to play a role.

Hidradenitis suppurativa often sets in after puberty, and before age 40 in most cases. It can persist for many years and can worsen over time if left untreated. Combined medical and surgical therapy can help manage the disease and prevent complications.

Stages of Hidradenitis Suppurativa

Although HS is usually classified by severity rather than distinct disease types, doctors commonly use the Hurley staging system. Take a look at the various stages of hidradenitis suppurativa below:

  1. Hurley Stage I This is the mildest stage. Small painful lumps or abscesses appear without significant scarring or tunnel formation.

  2. Hurley Stage II Patients develop recurring abscesses that burrow into the skin but are limited in extent. Scarring can begin to appear.

  3. Hurley Stage III This is the most severe stage. Multiple interconnected tunnels, extensive scarring and widespread inflammation occur across larger skin areas.

How Common is Hidradenitis Suppurativa in India?

The exact prevalence of hidradenitis suppurativa in India is not yet known, as large population-based studies are lacking. As per multiple studies, the prevalence of HS varies from 0.1% to 4% and is more common in women. Most available data comes from small hospital-based studies, suggesting that the condition may remain under-recognised or diagnosed late.

What are the Symptoms of Hidradenitis Suppurativa?

Hidradenitis suppurativa causes recurrent, painful lumps in areas where the skin rubs together, such as the underarms, groin, inner thighs, buttocks and beneath the breasts. Symptoms may begin with mild discomfort or a single lump and later progress to abscesses, draining wounds, tunnels beneath the skin and permanent scarring.

Some of the common early warning signs and advanced stage symptoms of hidradenitis suppurative are listed below:

Early Warning Signs Advanced Symptoms
  • Tender painful lump beneath the skin

  • Burning, itching or warmth before lesions appear

  • Small blackheads (double-ended comedones)

  • Mild redness and localised swelling

  • Pain in areas where skin rubs together

  • Recurring lumps in the same location

  • Mild discomfort during daily activities

  • Recurrent painful abscesses

  • Persistent drainage of pus or blood-stained fluid

  • Formation of sinus tracts (tunnels beneath the skin)

  • Thick scarring and skin fibrosis

  • Restricted movement due to pain and scarring

  • Chronic pain and foul-smelling discharge

  • Extensive skin thickening and multiple interconnected lesions

Diseases Similar to Hidradenitis Suppurativa

Hidradenitis suppurativa may resemble other conditions that cause painful lumps, pustules or abscesses around hair follicles. Folliculitis and recurrent boils are two common conditions that may need to be distinguished from HS through examination, symptom history and, if infection is suspected, laboratory testing.

A brief comparison of these three conditions is given below for better understanding:

Hidradenitis Suppurativa Vs. Folliculitis Vs. Recurrent Boils

Feature Hidradenitis Suppurativa Folliculitis Recurrent Boils
How It Happens Chronic inflammation develops after hair follicles become blocked, leading to deep lumps, abscesses and tunnels beneath the skin. Hair follicles become inflamed or infected, commonly because of bacteria, friction, shaving or occlusion. A deeper bacterial infection of a hair follicle causes a pus-filled abscess called a boil or furuncle.
Location Commonly affects the underarms, groin, inner thighs, buttocks and beneath the breasts. Can affect most hair-bearing areas, including the face, scalp, thighs, buttocks and trunk. May develop anywhere with hair follicles, commonly on the face, neck, thighs, buttocks or areas exposed to friction.
Associated Symptoms Deep painful lumps, recurrent abscesses, blackhead-like spots, draining wounds, tunnels and permanent scarring may occur. Small red or pus-filled bumps may cause itching, tenderness or mild soreness around individual hair follicles. Painful, red and swollen lumps may enlarge, fill with pus and rupture or drain.
Severity A chronic condition that may progressively cause interconnected tunnels, persistent wounds and extensive scarring. Usually superficial and mild, although deeper or widespread infection may require treatment. Usually resolves with appropriate care, but repeated or clustered boils may indicate persistent bacterial carriage or another risk factor.
Can It Be Reversed? HS cannot usually be permanently cured, but treatment can reduce flare-ups, inflammation and further scarring. Folliculitis often clears after the cause is removed or treated, although it may recur. Individual boils can heal with drainage or other treatment, but recurrence is possible if the underlying cause remains.

What Causes Hidradenitis Suppurativa?

Several factors and risk factors contribute to HS, which include:

  1. Causes
    • Blocked Hair Follicles: The primary event that triggers inflammation.
    • Immune System Dysfunction: An abnormal immune response can worsen inflammation.
    • Hormonal Changes: Hormones may influence the onset and severity of symptoms.
    • Skin Friction: Repeated rubbing in skin-fold areas can aggravate existing lesions.
  2. Risk Factors
    • Family History: Having a close relative with HS increases the risk.
    • Obesity: Excess weight can increase skin friction and inflammation.
    • Smoking: Tobacco use is strongly linked to the development and progression of HS.
    • Metabolic Conditions: Conditions such as diabetes and metabolic syndrome are associated with a higher risk of HS.

What are the Complications of Hidradenitis Suppurativa?

Complications associated with untreated HS are:

  • Permanent Scarring: Chronic inflammation scars skin tissue.

  • Formation of Tunnels: Interconnected tracts beneath the skin may develop as a result of chronic illness.

  • Anaemia: In severe or long-standing HS, ongoing inflammation, blood loss from draining lesions and reduced iron use in the body can lead to low haemoglobin levels (anaemia).

  • Secondary Infection: Open lesions are prone to infection.

  • Restricted Mobility: Movement may be restricted due to pain and scarring.

  • Lymphoedema: Chronic inflammation can disrupt lymphatic outflow.

  • Emotional Distress Anxiety: Depression and social isolation are very common.

  • Chronic Pain: Persistent inflammation can lead to persistent pain.

  • Skin Changes: The skin can become thickened or toughened over time.

  • Risk of Rare Skin Cancer: The likelihood may be increased in areas affected by long-standing, severe illness.

When Should I See My Healthcare Provider?

You should seek medical advice if:

  • Painful lumps recur frequently, particularly at the same site of the body.

  • Symptoms last for weeks and lesions increase abnormally.

  • Lesions release pus or blood with a foul odour

  • Scarring starts to show up

  • Pain due to inflammation causes difficulty in moving, making everyday tasks difficult.

  • Signs of fever or infection demand urgent medical assessment

How is Hidradenitis Suppurativa Diagnosed?

Doctors usually diagnose hidradenitis suppurativa through the following methods:

  1. Medical History Assessment The doctor asks about symptom duration, frequency of flare-ups, family history and possible triggers.

  2. Physical Examination The affected skin is examined for painful lumps, abscesses, scarring and tunnel formation.

  3. Drainage Sample Testing If pus or drainage is present, a sample may be tested to rule out infection.

  4. Imaging Studies Ultrasound may be used to identify tunnels beneath the skin and assess disease severity.

  5. Additional Health Screening Doctors may check for conditions commonly associated with HS, such as obesity, diabetes, hypertension and polycystic ovary syndrome (PCOS).

Diagnostic Overview Table

Test Purpose What the Doctor Checks
Medical History Assessment Understand symptoms and risk factors Duration and frequency of symptoms, triggers and family history
Physical Examination Identify characteristic skin changes Painful lumps, scarring, sinus tracts and affected body areas
Drainage Sample Testing Rule out infection Presence of bacteria or signs of secondary infection in pus
Ultrasound (Imaging Study) Detect hidden disease severity Presence of tunnels (sinus tracts) and depth of inflammation
Additional Health Screening Identify associated conditions Obesity, diabetes, hypertension and PCOS

How is Hidradenitis Suppurativa Managed or Treated?

Common measures to treat or manage HS are:

  1. Medical Treatment

    Doctors may recommend:

    • Topical anti-inflammatory treatments
    • Oral antibiotics to control the inflammation
    • Medicines to deal with pain
    • Hormonal therapy in certain patients
    • Biologic therapies for moderate to severe disease
  2. Surgical Treatment

    Advanced disease may require:

    • Drainage procedures
    • Unroofing of tunnels
    • Laser treatments
    • Surgical removal of severely affected tissue

Your HS treatment depends on how severe your ailment is and on your specific health needs.

Hidradenitis Suppurativa and Related Health Conditions

HS is frequently seen with other health conditions. These include obesity, diabetes, metabolic syndrome, hypertension, polycystic ovarian syndrome (PCOS), inflammatory bowel disease and depression. Managing these issues might enhance overall health outcomes and support HS treatment.

Common Medicines Used to Treat Hidradenitis Suppurativa

Medicines for hidradenitis suppurativa help control inflammation, reduce painful lumps and prevent further abscesses, tunnels and scarring. Treatment depends on disease severity, affected areas, previous response and the patient’s overall health.

Common medications used to treat HS may include:

  • Clindamycin: Topical clindamycin may reduce inflamed lumps and pustules in mild, localised hidradenitis suppurativa.

  • Doxycycline: This oral medicine may be prescribed for widespread mild-to-moderate disease because of its antibacterial and anti-inflammatory effects.

  • Clindamycin and Rifampicin: This oral combination may be considered for moderate-to-severe disease that has not improved adequately with tetracycline medicines.

  • Triamcinolone Acetonide: This corticosteroid may be injected into selected painful, inflamed lumps to provide short-term relief from swelling and discomfort.

  • Metformin: Metformin may be considered when hidradenitis suppurativa occurs with insulin resistance, type 2 diabetes or polycystic ovary syndrome (PCOS).

  • Spironolactone: This hormonal medicine may help selected women whose flare-ups are associated with menstrual cycles or androgen-related symptoms.

  • Adalimumab: This injectable biological medicine may reduce abscesses and inflammatory lumps in moderate-to-severe disease that has not responded to conventional treatment.

  • Secukinumab: This injectable biological medicine may be considered for adults with moderate-to-severe active disease when standard systemic treatment has not provided adequate control.

  • Paracetamol and Ibuprofen: These medicines may relieve pain during flare-ups but do not treat the underlying inflammation or prevent disease progression.

Note: The medicines listed above are commonly used to manage hidradenitis suppurativa. The treatment plan depends on disease severity, frequency of flare-ups, associated medical conditions and previous response to therapy. Never start, stop or change any medicine without consulting a qualified dermatologist.

Living With Hidradenitis Suppurativa: Daily Challenges and Patient Well-Being

Living with hidradenitis suppurativa may involve recurrent pain, wound care and long-term medical treatment. Draining lesions, scarring and unpredictable flare-ups can affect mobility, work, relationships and emotional health. Research has also found that greater disease severity is associated with a poorer quality of life.

Some of the daily challenges and essential care points for hidradenitis suppurative patients are mentioned below:

  1. Challenges
    • Pain and Restricted Movement: Painful lumps and scarring in the underarms, groin or thighs may make walking, sitting, exercising or moving the arms difficult.
    • Drainage and Odour: Ruptured lesions may leak blood or pus, requiring frequent dressing changes and causing concern about staining or odour.
    • Work and Social Disruption: Flare-ups, medical appointments and discomfort may interfere with work, education, travel and social activities.
    • Clothing Difficulties: Tight clothing, friction, heat and sweating may irritate affected areas and worsen discomfort.
  2. Patient Well-Being
    • Wound Care: Gentle cleansing, suitable dressings and following the dermatologist’s instructions can help protect draining areas and reduce irritation.
    • Emotional Support: Pain, visible lesions, odour and scarring may contribute to embarrassment, anxiety or depression and may require counselling or psychological support.
    • Regular Treatment: Taking prescribed medicines and attending dermatology follow-up appointments can help control inflammation and limit further scarring.
    • Lifestyle Support: Avoiding smoking, maintaining a suitable weight and reducing friction in affected areas may support disease management when medically appropriate.
  3. Expenses
    • Consultations and Monitoring: Regular dermatologist visits and blood tests may create recurring costs, particularly during systemic or biological treatment.
    • Medicines: Expenses may include topical treatment, antibiotics, pain relief, hormonal medicines or injectable biological medicines.
    • Dressings and Skin Care: Gauze, absorbent dressings, cleansers and protective clothing may add to routine household expenses.
    • Procedures and Surgery: Advanced disease may require repeated drainage procedures, unroofing surgery or wide surgical excision, increasing the overall cost of treatment.

What is the Prognosis of Hidradenitis Suppurativa?

Hidradenitis suppurativa is generally not a curable disease. However, the long-term prognosis is favourable as it is possible to effectively manage the condition with early diagnosis, appropriate treatment and lifestyle modifications.

Many patients experience periods of remission where symptoms improve significantly. Treatment can help with flare-ups, discomfort and scarring, but the condition can relapse, which makes regular monitoring essential.

How Can I Prevent Hidradenitis Suppurativa?

Some effective measures to prevent HS are:

  • Maintain a healthy weight, as this measure may reduce skin friction.

  • Avoid smoking because it is a recognised risk factor.

  • Wear loose clothes to reduce irritation.

  • Avoid constant rubbing in affected areas.

  • Control diabetes and metabolic conditions, as reducing inflammation can lead to improved overall health.

  • Keep skin clean and dry to reduce the risks of getting HS.

  • Seek early treatment to prevent HS progression.

  • Ensure regular monitoring to support long-term disease control.

Frequently Asked Questions (FAQs)

  • Q1. What are the stages of hidradenitis suppurativa?

    Ans: The Hurley stage method is used to classify hidradenitis suppurativa severity. Stage I has abscesses, while Stage II has recurrent abscesses with minor tunnel development. Stage III is the most advanced stage that comes with extensive tunnelling, widespread lesions and considerable scarring.
  • Q2. Can hidradenitis suppurativa be cured?

    Ans: No, hidradenitis suppurativa is not completely curable at present. However, HS patients are often able to control flare-ups, minimise symptoms and prevent the progression of the condition with early identification and appropriate treatment.
  • Q3. What foods should I avoid if I have hidradenitis suppurativa?

    Ans: It depends on your symptoms and the causes. However, patients often report that symptoms of hidradenitis suppurativa increase after eating highly processed foods, sugary foods or foods that often cause inflammation.
  • Q4. Is hidradenitis suppurativa covered by health insurance?

    Ans: Yes, many comprehensive health insurance plans may cover treatment of hidradenitis suppurativa. It usually covers hospitalisation, diagnostic testing, procedures and associated treatment costs, depending on the policy terms and conditions. Pre-existing conditions may be subject to waiting periods of up to 3 years.
  • Q5. When should I see a doctor for hidradenitis suppurativa?

    Ans: It is recommended to seek medical advice for HS if the painful lumps keep coming back, the symptoms get worse, drainage begins, or scarring occurs. Early treatment may reduce disease progression and improve long-term symptom control of hidradenitis suppurativa.
  • Q6. How is hidradenitis suppurativa different from acne?

    Ans: Yes. Hidradenitis suppurativa generally affects the skin-fold regions and is likely to recur. It can often result in severe abscesses, tunnels and scarring. Acne primarily affects the face, chest and back.
  • Q7. Can children get hidradenitis suppurativa?

    Ans: Yes, children can get hidradenitis suppurativa. However, the risk of developing HS before puberty is low. The condition usually sets in during adolescence when hormonal changes take place.
  • Q8. Can pregnant women develop hidradenitis suppurativa?

    Ans: Yes, pregnant women can develop hidradenitis suppurativa. Symptoms may get better or worse because of hormonal changes in pregnancy.
  • Q9. Can older adults develop hidradenitis suppurativa?

    Ans: Yes, hidradenitis suppurativa can occur in older individuals. While symptoms tend to develop early in life, the condition may develop in later years in some cases.
  • Q10. Can hidradenitis suppurativa go away on its own?

    Ans: No, hidradenitis suppurativa normally does not resolve on its own. Some patients may be symptom-free in intervals, but the condition often recurs. Early diagnosis and continuing management are thus important.
  • Q11. What is the main cause of hidradenitis suppurativa?

    Ans: There is no conclusive evidence to determine the exact cause of hidradenitis suppurativa in medicine. However, experts suggest clogged and irritated hair follicles are the usual causes behind HS. Genetic predisposition, immunological dysregulation, hormonal effects and environmental stressors may also be responsible in some cases.
  • Q12. What triggers hidradenitis suppurativa?

    Ans: Common factors for hidradenitis suppurativa include smoking, obesity, friction, heat, sweat and hormones. Triggers of HS are different for different patients and may not affect everyone in the same way. Noting and avoiding identified personal triggers might help minimise flare-ups and promote better symptom management over time.
  • Q13. What is Stage 1 hidradenitis suppurativa?

    Ans: Hurley Stage I, also known as Stage 1 hidradenitis suppurativa, is the mildest form of the illness. Patients develop solitary painful lumps or abscesses, without tunnels under the skin. Usually, there is not much scarring at this time.
  • Q14. Which body areas are most commonly affected by hidradenitis suppurativa?

    Ans: HS most commonly affects areas where skin rubs together, such as the armpits, groin, buttocks, inner thighs and under the breasts.
  • Q15. What does HS smell like?

    Ans: Yes, hidradenitis suppurativa can have a foul odour when lesions release pus or fluid. The odour varies from patient to patient but is typically connected to drainage, bacteria and trapped moisture in the affected areas.
