Does HS Run in Families? 9 Things to Know About Genetics, Risk, and Flare Triggers
Hidradenitis suppurativa can feel confusing enough when you are dealing with your own skin. It becomes even more emotional when you start wondering whether your child, sibling, parent, or another relative may also develop it.
The honest answer is this: HS can run in families, but family history is not destiny.
Hidradenitis suppurativa, or HS, is a chronic inflammatory skin condition that causes painful lumps, abscesses, tunnels under the skin, drainage, odor, and scarring. It often appears in areas where skin rubs together, such as the armpits, groin, inner thighs, buttocks, under the breasts, and around the genitals. The American Academy of Dermatology confirms that HS is not contagious and usually develops where skin touches skin. (American Academy of Dermatology)
Research suggests that genetics may play a role for many people with HS. A 2024 review reported that about 30 percent of people diagnosed with HS report a positive family history, although clear single-gene inheritance appears uncommon. (PMC)
Here are 9 things to know about HS, genetics, family risk, and flare triggers.
1. HS can run in families
Many people with HS have a relative who also has painful boils, recurring lumps, drainage, or scarring in similar body areas. Sometimes the family connection is obvious. Other times, it gets missed because relatives may call it “boils,” “abscesses,” “ingrown hairs,” “sweat bumps,” or “bad skin.”
Mayo Clinic lists family history as a risk factor for hidradenitis suppurativa and notes that a tendency to develop HS can be inherited. (Mayo Clinic)
This does not mean every child of someone with HS will develop HS. It means the risk may be higher when HS exists in the family.
2. Genetics may increase risk, but HS is usually complex
Some health conditions are caused by a single gene. HS is usually more complicated than that. The current evidence points to a mixture of genetic, immune, hormonal, environmental, and lifestyle-related influences.
A 2025 British Journal of Dermatology review described HS as a complex inflammatory disease and noted that newer genetic research suggests multiple genes may contribute to HS in a polygenic way, meaning more than one gene may influence risk. (OUP Academic)
This is important because it prevents blame. HS is not caused by one simple choice, and it is not caused by poor hygiene. A person can carry genetic risk and still have symptoms shaped by inflammation, hormones, friction, smoking, weight, stress, heat, sweat, and access to treatment.
3. A family history should help you recognize HS earlier
When HS runs in a family, the biggest advantage is awareness. If you know what HS looks like, you can recognize symptoms earlier and get dermatology care sooner.
Early symptoms may include:
-
Painful deep bumps under the skin
-
Recurring boils in the armpits, groin, inner thighs, buttocks, or under the breasts
-
Lesions that drain fluid or blood
-
Bumps that return in the same areas
-
Blackheads in pairs or clusters
-
Scarring after repeated flares
-
Tunnels under the skin
The American Academy of Dermatology describes HS as painful lumps deep in the skin that usually develop where skin touches skin. (American Academy of Dermatology)
Early diagnosis matters because treatment can help reduce flares, drainage, pain, scarring, and tunnels.
4. HS is not contagious
This needs to be said clearly. HS does not spread from person to person.
You cannot catch HS by sharing clothes, sitting on the same toilet, touching someone’s skin, using the same towel, or being intimate with someone who has HS. The American Academy of Dermatology states that HS is not contagious. (American Academy of Dermatology)
This matters for families because HS can create shame and secrecy. When several relatives have similar symptoms, it may look like something is being “passed around.” The family link is more likely related to shared genetic risk and possibly shared environmental factors, not contagion.
5. HS is not caused by poor hygiene
People with HS often hear hurtful advice: “wash better,” “scrub harder,” “use stronger soap,” or “stop sweating.” This advice can make HS worse because harsh scrubbing irritates inflamed skin.
Cleveland Clinic Abu Dhabi notes that hidradenitis suppurativa is not contagious and is not the result of poor hygiene. (Cleveland Clinic Abu Dhabi)
A gentle skin routine is helpful, but HS is an inflammatory skin disease. The goal is to reduce irritation, protect the skin barrier, manage drainage safely, and work with a dermatologist.
6. Hormones may influence HS flares
HS often begins after puberty, which suggests hormones may play a role for some people. Many women notice flares before their period, during hormonal shifts, or around major reproductive changes.
Cleveland Clinic Abu Dhabi lists fluctuating sex hormone levels among risk factors linked with HS, especially around puberty or before menopause. (Cleveland Clinic Abu Dhabi)
Hormones do not explain every case, but they may help explain why HS can change over time. If flares follow a menstrual pattern, write it down and bring it to your healthcare provider. This can help guide treatment discussions.
7. Smoking can worsen risk and severity
Smoking is one of the most consistently discussed HS risk factors. It may affect inflammation, immune activity, wound healing, and disease severity.
Mayo Clinic lists smoking as a risk factor for HS. (Mayo Clinic) Cleveland Clinic also notes that, although some risk factors such as family history are out of your control, steps such as quitting smoking may help lower the risk of flares and complications. (Cleveland Clinic)
Quitting smoking is not easy, and people with HS should not be shamed. Still, if you smoke, quitting may be one of the most meaningful health steps for your skin and overall inflammatory health.
8. Weight, friction, heat, and sweat may trigger flares
HS often develops in areas where skin rubs together. Friction, heat, and sweat can make symptoms feel worse for many people.
Mayo Clinic lists obesity as a risk factor for HS and explains that the condition tends to occur near hair follicles where there are sweat and oil glands, especially where skin rubs together. (Mayo Clinic)
This does not mean weight is the only cause of HS. Thin people can have HS too. Weight can influence friction, inflammation, sweat, and skin fold irritation, but it is only one part of the picture.
Practical flare-reduction tips include:
-
Wear loose, breathable clothing
-
Avoid tight waistbands and rough seams
-
Change out of sweaty clothes when possible
-
Use soft dressings to reduce rubbing over draining areas
-
Keep affected areas dry without harsh powders or irritating products
-
Choose gentle deodorants or antiperspirants if tolerated
-
Avoid aggressive shaving over active lesions
Small friction-reducing changes can help protect sensitive areas.
9. Inflammation and lifestyle patterns can influence symptoms
HS is an inflammatory condition, so anything that affects inflammation, immune stress, sleep, blood sugar, smoking, stress, and recovery may influence how the body feels.
Lifestyle habits cannot cure HS, but they may support the body alongside medical treatment. A helpful routine may include:
-
Gentle cleansing without scrubbing
-
Dermatologist-guided treatment
-
Lower-friction clothing
-
Smoking cessation support if needed
-
Blood sugar-conscious meals
-
More vegetables, fruits, beans, peas, fish, nuts, seeds, herbs, and spices
-
Better sleep routines
-
Stress support
-
Symptom and trigger tracking
Hapi Moon’s anti-inflammatory tea formulation includes turmeric, bitter melon leaves, sorrel, guinea hen weed, cinnamon, and black pepper. The formulation describes the product as a loose leaf tea for pain and inflammation reduction.
A responsible way to position this tea is as a caffeine-free herbal wellness blend that may fit into a routine focused on hydration, inflammation balance, and daily comfort. It should not be described as a treatment or cure for HS, abscesses, infections, drainage, wounds, tunnels, or scarring.
Speak with a healthcare provider before using herbal products regularly if you are pregnant, trying to conceive, breastfeeding, taking blood thinners, diabetes medication, blood pressure medication, immune-suppressing medication, or preparing for surgery.
What to do if HS runs in your family
If HS runs in your family, you do not need to panic. You need awareness and earlier action.
Here are practical steps:
-
Learn what HS looks like
-
Avoid dismissing recurring boils as simple ingrown hairs
-
See a dermatologist early if bumps return in the same areas
-
Tell your doctor about family history
-
Track flares, menstrual timing, sweat, friction, stress, smoking, food patterns, and drainage
-
Avoid squeezing or cutting bumps at home
-
Use gentle skin care
-
Support family members emotionally instead of shaming symptoms
Family history can be useful information. It can help shorten the time between symptoms and diagnosis.
When to see a dermatologist
Book a dermatology appointment if you or a family member has:
-
Recurring painful boils
-
Lumps in the armpits, groin, buttocks, inner thighs, or under the breasts
-
Drainage or odor
-
Scarring
-
Tunnels under the skin
-
Pain that affects walking, sitting, intimacy, work, or sleep
-
Flares that return in the same area
-
Symptoms that worsen around the period
-
Signs of infection, fever, or spreading redness
HS can be treated. Treatment may include topical medication, oral medication, hormonal approaches, biologics, pain management, wound care, procedures, or surgery depending on severity. Mayo Clinic notes that combined medical and surgical therapy can help manage HS and prevent complications. (Mayo Clinic)
Final thoughts
HS can run in families, and genetics may increase risk. Still, HS is not a simple genetic sentence. It is a complex inflammatory condition shaped by family history, immune activity, hormones, friction, heat, sweat, smoking, weight, stress, and treatment access.
The most important takeaway is awareness. If painful bumps keep returning in the same areas, especially in skin folds, do not assume it is poor hygiene or ordinary boils. Ask about HS. Share your family history. Seek dermatology care early.
HS is not contagious. HS is not your fault. Earlier care can make a real difference.
