Hidradenitis Suppurativa Statistics: Separating Fact from Fiction

How much do we really know about Hidradenitis Suppurativa (HS)? The answer is complicated. Despite being a common condition, there are gaps in the data due to misdiagnoses, underreporting, and limited research. Let’s break down what we know—and what remains uncertain.



Common Myths About HS

Which of the following is true?

  1. HS most commonly occurs in women aged 22–40.

  2. It’s rare for HS to occur before puberty.

  3. It’s rare for HS to occur after menopause.

  4. None of the above.


Answer: None of the above.

While these statements are widely circulated, they oversimplify a complex condition. HS doesn’t adhere to strict age or gender boundaries. In fact, individuals can develop HS before puberty, after menopause, or at any other stage of life.

Age, Gender, and HS: What the Data Tells Us

The age groups most often associated with HS typically refer to when people are diagnosed, not when symptoms first appear. This distinction is important because many people live with HS for years before receiving an accurate diagnosis. Reasons for this include:

  • Delays in seeking care: People may not recognize their symptoms as serious or may not seek medical attention until their condition worsens.

  • Misdiagnoses: HS is often mistaken for boils, infections, or acne, leading to further delays in proper treatment.


While HS is frequently reported to affect more women than men in North America, this pattern doesn’t hold globally. In some Eastern countries, men are diagnosed with HS at higher rates. This discrepancy likely reflects cultural, societal, and healthcare access factors rather than the true prevalence of HS among genders.



Why Does It Seem Like HS Affects Women More?

Several factors may explain why women appear to be more commonly diagnosed with HS:

  1. Healthcare-Seeking Behavior: Women are statistically more likely to visit a doctor for medical issues, including HS.

  2. Communication: Women are often more vocal about their experiences with HS, both in personal networks and public forums.

  3. Bias in Data: Many studies are based on populations where women are more likely to participate or report their symptoms.


Conversely, men and certain ethnic groups may be less likely to seek care or discuss their symptoms, leading to underrepresentation in data (read more about HS in males here). Misdiagnoses and cultural stigma further compound this issue, making it challenging to draw definitive conclusions about gender and ethnic prevalence.



The Truth About HS Statistics

The reality is that no large-scale, globally comprehensive study on HS prevalence has been conducted. Current data relies on small sample sizes, localized studies, and patient self-reports, which means the statistics we have are only rough estimates.


  • Gender Differences: Without global studies, we can’t accurately determine whether HS affects men or women more often.

  • Ethnicity and Access to Care: Societal factors heavily influence who seeks and receives treatment, skewing the available data.

  • Age Ranges: While HS is often associated with adults, cases in children and older adults are frequently underreported or overlooked.



Why Your Participation Matters

Every time you participate in an HS study or survey, you contribute to a clearer understanding of this condition. Better data means:

  • Improved diagnosis rates

  • Increased research funding

  • More inclusive treatment options


Without accurate statistics, many people living with HS remain invisible in the data—and untreated in the healthcare system.



Final Thoughts

When it comes to HS, there’s still much we don’t know. However, by staying informed, participating in research, and advocating for better awareness, we can help close the gaps in understanding.


Remember: the more data we collect, the closer we come to ensuring that every person affected by HS is seen, heard, and cared for.


Let’s work together to dispel the myths and bring the realities of HS into the spotlight.
