HS involves more than the skin
HS is increasingly understood as a systemic inflammatory condition. In studies of large patient groups, certain metabolic, gastrointestinal, joint and mental-health conditions occur more often than in comparison groups without HS.
These associations are described at group level. They do not mean that an individual with HS has or will develop any of these conditions, and they do not establish a one-way chain of cause and effect.
How often they occur also differs substantially between regions and study populations. That is why you will find no percentages on this page: a figure from a North American clinic cohort says little about your situation in Germany.
Two different questions — worth keeping apart
The first question is: is my routine preventive care up to date? Blood pressure, blood sugar and blood lipids are routine adult health topics anyway, and in Germany they are part of the general health check-up.
The second question is: do I have symptoms that deserve to be looked at in their own right? This is not about investigating on suspicion — it is about not filing a symptom under HS automatically.
Whether every person with HS should be screened for every associated condition is not settled. A symptom- and risk-based approach — routine prevention plus deliberately raising symptoms — is what this page reflects.
Heart, circulation and metabolism
Metabolic and cardiovascular conditions are among the best-studied companions of HS and are consistently named in comorbidity-assessment recommendations.
In practice that usually means nothing exotic: have your blood pressure measured, know when your last check-up was, and mention at the next appointment that you have HS.

Gut and digestion
Inflammatory bowel disease, especially Crohn’s disease, is one of the best-established connections in HS. In the perianal area the two conditions can also look similar, which makes them harder to tell apart.
Persistent diarrhoea, recurrent abdominal pain, blood in the stool or unintended weight loss have many possible causes. What matters is that they get raised rather than quietly attributed to HS.

Joints and back
Inflammatory joint disease, including spondyloarthritis, occurs more often in HS. Inflammatory back pain characteristically eases with movement rather than with rest, and morning stiffness lasts longer.
Those features are not a test and not a diagnosis. They only help to stop persistent symptoms being written off as ordinary muscular strain from the outset.

Cycle and hormones
PCOS is described alongside HS more often than expected. Both conditions can involve skin changes and both are often recognised late, which is what makes the connection practically relevant.
HS on its own is not a reason for hormone testing, though. If changes to your cycle or increased hair growth concern you, that is the reason to raise it — and the clinician decides what is appropriate.

Blood and energy
Anaemia occurs more often in people with HS than in comparison groups in pooled research, and persistent fatigue is a common part of living with HS. The two are easy to conflate, but fatigue does not diagnose anaemia, and anaemia is not automatically iron deficiency.
If tiredness feels disproportionate to your usual HS burden, or comes with symptoms such as breathlessness, palpitations or dizziness, that is worth raising in its own right rather than filing it under HS.
Pain, itch and draining wounds can also disrupt sleep, which can add to the exhaustion without being the same thing as anaemia. Both deserve their own explanation rather than a shared one.

Mental health
The psychological burden of HS is well documented and explicitly included in comorbidity-assessment recommendations. Pain, drainage, odour and the location of affected areas all affect everyday life, work and relationships.
This page deliberately runs no questionnaire and produces no score. It simply records that this belongs in the same appointment as everything else.

Other skin conditions
Tell your dermatologist if you also have recurrent pilonidal disease, severe acne-like disease elsewhere on the body, or unusual inflammatory ulcers. These associations are recognised and can matter for how your condition is understood.
You will deliberately not find a full list of rare syndromes here. For the great majority of readers it would create more worry than value — and it belongs in a dermatological assessment anyway.
Your regular German health check-up
A large part of what this page covers is not a special service at all — it is part of the general preventive care available to people with statutory health insurance in Germany anyway.
The check-up does not replace dermatological treatment of HS and is not an HS screening. It is the place where blood pressure, metabolism and risk profile get discussed regularly.

What this page cannot establish
It cannot establish whether you have an associated condition, and it calculates no personal risk. It does not replace a medical examination and recommends no particular laboratory test.
What it can do: show you which topics exist at all, and help you raise two or three of them at your next appointment.
