HS, Sleep and Fatigue: Why Hidradenitis Suppurativa Can Be So Exhausting

Living with hidradenitis suppurativa (HS) can be tiring in ways that are not visible to anyone else.

Finding a position that does not press on an affected area is genuinely difficult when the lesions are under the arms, in the groin, on the buttocks or under the breasts.

And sometimes the problem is a different one entirely: you sleep for hours and still feel emptied out the next day.

Research increasingly treats both sleep disturbance and fatigue as real parts of the burden of HS rather than as side notes. But there is a second message in that same research that matters just as much: fatigue should not automatically be explained by HS alone.

This article covers what the evidence supports, what remains uncertain, what is worth writing down, and what is worth saying out loud at your next appointment.

Educational content only. This article explains associations reported in research. It cannot identify the cause of your fatigue and it does not replace an individual medical assessment.

Key takeaways

• Several observational studies report poorer sleep quality and a higher occurrence of sleep problems in people with HS than in comparison groups.
• Pain, itch and lesion drainage are the disruptions patients describe most consistently, and recent work adds the practical and emotional load of wound care.
• Fatigue and sleepiness are different experiences. Fatigue is the one most likely to be missed in a short appointment.
• Exhaustion in a person with HS is not proof that HS is the only cause. Sleep, mood, other conditions and medication can all contribute.
• The most useful thing you can bring to an appointment is a concrete pattern — which nights, which reason, and what the next day looked like.

Does HS really affect sleep?

Yes, although how strongly, and for what reason, varies a great deal between individuals.

A systematic review published in 2023 pulled together seven studies covering a combined total of around 343,870 participants. It reported a greater likelihood of sleep disorders among people with HS, and several of the included studies found poorer sleep quality linked to HS symptoms — pain and itch in particular.

A separate study compared 108 people with HS against 50 people without it and looked specifically at what was interfering with sleep. Both pain and itch were associated with sleep difficulty. Pain showed the clearest relationship, associated with poorer subjective sleep quality, shorter sleep and more daytime dysfunction.

More recent qualitative work, published in 2026, gathered perspectives from both people living with HS and the healthcare professionals treating them. Sleep disturbance was described as commonly linked to pain, itching and lesion drainage. Participants also described the effect as cumulative rather than nightly — which matches something many patients recognise straight away. One broken night is survivable. Six broken nights in a fortnight is a different problem.

That same paper is worth noting for a second reason: it described fatigue as underexplored in research and infrequently discussed in clinical practice. In other words, the gap you may have noticed between how tired you feel and how often anyone asks about it is a documented gap, not an impression.

What can make sleeping with HS difficult

Pain

Pain can keep you from falling asleep, wake you during the night, or rule out a position you would otherwise sleep in.

Location shapes the problem. A lesion on the buttocks can make lying on your back uncomfortable. Groin or inner-thigh involvement can make side sleeping awkward. Underarm lesions make arm position matter in a way it never did before.

There is no single correct sleeping position for HS, and anyone who offers you one is guessing. The practical aim is comfort without adding pressure or friction to skin that is already painful — which usually means experimenting with pillows for separation and support rather than trying to hold one prescribed posture.

Itch

Itch is easy to underplay in HS because pain dominates the conversation, but it can be substantial, and research has linked it directly with disturbed sleep.

If itching is repeatedly waking you, or you are scratching affected skin in your sleep, that is worth naming specifically rather than reporting “poor sleep” and leaving your clinician to guess which of the possible causes applies. HS and itch covers when HS tends to itch and what that timing may — and may not — mean.

Drainage and wound care

Draining lesions interrupt sleep in several ways at once:

• a dressing needs changing during the night;
• clothing or bedding becomes wet;
• you wake to check whether a wound has leaked;
• the anticipation of leakage itself makes it harder to settle.

The practical and emotional load of wound management can therefore cost you rest even on nights when pain is not the main issue. Dressing choice matters here, but it is genuinely individual: what a wound needs depends on its location and how much it is draining. Follow the plan your own care team has given you, and treat “my current dressings do not survive the night” as a legitimate thing to raise at an appointment rather than a problem to solve alone.

Worry and anticipation

Not every bad night is caused directly by a lesion. You may also be lying awake wondering whether a flareFlare: A period of acute worsening in a chronic condition. In Acne Inversa, a flare may be triggered by stress, hormonal changes, friction, or other factors and can manifest as new nodules, abscesses, or increased pain.FlareA period of acute worsening in a chronic condition.

That does not make the problem “only psychological”. Physical symptoms, anticipation and emotional burden interact, and a night disrupted by dread about leakage is still a night of lost sleep.

Fatigue is not the same as sleepiness

The two get used interchangeably in everyday speech, which is part of why fatigue gets lost in appointments.

Sleepiness is the pull towards falling asleep — nodding off in a meeting, on a sofa, in front of a screen.

Fatigue is broader, and often harder to describe:

• physical exhaustion;
• reduced energy;
• difficulty concentrating or holding a thread;
• ordinary tasks costing far more effort than they used to;
• feeling depleted even after resting.

The 2026 patient and healthcare-professional perspective paper describes fatigue as a potentially debilitating part of the HS burden that has been comparatively neglected in research. Patients in that work described it in terms of what it took away — capacity for work, for social life, for the things that would otherwise offset a difficult skin condition.

If you have ever finished a full night’s sleep and still felt like you had nothing to spend, you were describing fatigue, not sleepiness. It is worth using that distinction out loud, because it points a clinician in a different direction.

Having HS does not explain every cause of exhaustion

This is the part of the article that matters most, and it is the opposite of reassuring in a useful way.

There are many reasons a person may be persistently exhausted. Possible contributors include:

• interrupted or insufficient sleep;
• ongoing pain or itch;
• the mental-health burden of a chronic, visible, unpredictable condition;
• effects of medication;
• other health conditions, including ones that are common alongside HS;
• sleep disorders;
• anaemiaAnaemia: A shortage of haemoglobin or healthy red blood cells, which reduces how much oxygen the blood carries. Anaemia can have many causes, including iron deficiency, chronic inflammation, vitamin B12 or folate deficiency, and blood loss. In HS, anaemia occurs more often in observational studies than in comparison groups; which subtype is present is established by a blood test, not by a single symptom such as fatigue.AnaemiaA shortage of haemoglobin or healthy red blood cells, which reduces how much oxygen the blood carries.

Which of these applies to you is not something a website can work out, and this article is not going to pretend otherwise. What it can tell you is that the reasoning “I have HS, so of course I am tired” quietly closes a door that should stay open.

Anaemia is worth calling out specifically, because it is genuinely more common in people with HS than in comparison groups — but fatigue alone cannot diagnose it, and anaemia is not automatically iron deficiencyIron Deficiency: A state in which the body's available or stored iron is reduced. Iron deficiency can exist without anaemia, or progress to iron-deficiency anaemia if it starts to impair the production of red blood cells.

HS, anaemia and iron deficiency covers what the evidence shows and why inflammation can make iron results harder to read.

Patient guidance from other reputable HS sources makes the same point: fatigue can have several contributors, and ongoing fatigue is worth discussing with a healthcare professional rather than absorbing.

The practical version is short. Persistent exhaustion deserves its own sentence in your appointment. Do not assume your dermatologist knows how tired you are because you have discussed your skin. Those are two different conversations, and only one of them tends to happen by default.

HS and obstructive sleep apnea

Research has also reported an association between HS and obstructive sleep apnea — a condition in which breathing repeatedly pauses during sleep, fragmenting it without the person necessarily remembering waking.

The 2023 systematic review found a higher occurrence of sleep disorders including obstructive sleep apnea among people with HS, and a 2026 publication revisited the relationship specifically. It remains an active research question.

Two things this does not mean:

• it does not establish that HS causes sleep apnea;
• it does not mean everyone with HS should be tested.

What it does mean is that if your sleep concerns you — loud snoring, breathing pauses noticed by someone else, waking gasping, or heavy daytime sleepiness that does not fit how long you were in bed — that is a reason to describe it to a healthcare professional, rather than filing it under HS and moving on.

What to track before your appointment

You do not need a complicated sleep study at your kitchen table. One or two weeks of short notes is enough to change the quality of the conversation.

During the night, note:

• roughly what time you went to bed;
• how many times you remember waking;
• whether pain woke you;
• whether itch woke you;
• whether you needed a dressing change;
• whether drainage affected your sleep or bedding;
• whether one particular affected area made lying down difficult.

The next day, note:

• how rested you felt;
• whether you struggled to stay awake;
• whether fatigue affected work, study or caring responsibilities;
• whether concentration was difficult;
• whether you changed or cancelled anything because of exhaustion.

The point is not to arrive at a diagnosis. It is to turn this:

“I’m always tired.”

into this:

“Over the last ten nights, groin pain woke me on six of them, and I changed a dressing during the night three times. I am struggling to concentrate at work by mid-afternoon.”

The second version is something a clinician can actually work with. The first tends to get a sympathetic nod.

The site’s own symptom tracker already includes daily fields for fatigue and sleep quality alongside pain, drainage and mobility, and the summary view averages them over a week or a month — so if you would rather not keep a separate notebook, the pattern can come out of the entries you are already making.

Five questions worth taking to your appointment

1. Could my HS symptoms be contributing to my sleep problems?
2. Is my level of fatigue something we should look at separately, rather than assuming it is part of HS?
3. Could pain, itching or wound care be handled differently at night?
4. Could another health condition or any of my medication be contributing to how tired I feel?
5. Would it help if I tracked my sleep, fatigue or night-time symptoms before the next appointment?

These are conversation prompts, not treatment recommendations. Their job is to open a topic that otherwise tends to stay closed.

What can help tonight

There is no studied HS-specific sleep routine, and you should be sceptical of anyone who presents one.

General measures in NHS patient information for HS include allowing enough time for rest, keeping a reasonably regular bedtime, and making time to wind down before sleep. That advice is sensible and low-risk, but it is also generic — it is not specific to HS, and on its own it will not out-argue a painful lesion at two in the morning.

For HS-specific discomfort, it is usually more productive to aim at whatever is actually keeping you awake:

• Pain — if pain is regularly waking you, that is information about your pain management, not a personal endurance problem. Take it to your care team.
• Itch — say “itching wakes me” rather than “I sleep badly”. They lead to different conversations.
• Drainage — if your current wound-care approach is not coping with overnight drainage, that is a practical problem with a practical answer, and it belongs at an appointment.
• Pressure and friction — experiment with positions and with pillows for separation, aiming to keep weight off affected areas.
• Repeated exhaustion — document the pattern and raise fatigue as a separate item, not as a footnote to your skin.

One caution worth stating plainly: try not to let sleep become another area where you feel responsible for managing HS perfectly. There is no evidence that sleeping better will resolve the disease, and treating rest as another discipline to fail at helps nobody.

When to raise fatigue sooner

Arrange a medical assessment rather than assuming exhaustion is simply HS-related if:

• the exhaustion is new, or clearly worsening;
• you are repeatedly falling asleep unintentionally;
• fatigue is preventing you from doing ordinary daily activities;
• you have other unexplained symptoms alongside it;
• your sleep appears severely disrupted, or someone has noticed you stop breathing during it;
• the degree of tiredness itself worries you.

For changes that may need to be looked at more quickly — a wound that is behaving differently, rapidly worsening pain, fever, or feeling generally unwell — the site’s separate guide on when to get medical help sets out what warrants prompt contact.

The bottom line

Sleep and fatigue deserve to be treated as real parts of living with HS.

The research supports a relationship between HS and disturbed sleep, particularly where pain and itch are involved, and newer work identifies fatigue as a substantial burden that is discussed far less often than it is experienced.

The second half of that message is equally important. Having HS does not explain every cause of exhaustion, and assuming it does can delay finding something treatable.

If sleep or fatigue is significantly affecting your life, say so explicitly to a healthcare professional. Bringing two weeks of concrete examples makes that conversation considerably easier to have.
