Endometriosis
Endometriosis develops when tissue similar to the lining of the uterus settles elsewhere in the belly, around the organs. With each cycle, this tissue reacts, bleeds and inflames the areas where it has taken hold, which can cause pain far stronger than what those around usually associate with periods.
The condition moves in phases. Some days go by with no real discomfort, others pin the person to bed or make concentration impossible. On top of this pain there is often a tiredness built up over years. Understanding this irregular rhythm avoids having to justify oneself with each episode.
The hot water bottle pressed against the belly is, for many people affected by endometriosis, an everyday object more than a comfort remedy. It goes along with a dull pain that is not limited to period days and can come up at work, in class or in the middle of the night.
This pain was long played down, put down to slightly difficult periods. It is nonetheless very real and sometimes disabling. Being able to set out the context just once, without having to convince every new person that the pain exists, frees up precious energy for the rest.
Far more than painful periods
Reducing endometriosis to periods misses the essential point. The pain can arise at any moment in the cycle and affect the back, the belly, the legs. Added to this are less visible realities:
- a lasting tiredness, with no link to the previous night's rest;
- pain during ordinary actions such as sitting for a long time;
- an often long path before the condition is recognised;
- sometimes difficulty conceiving a child.
What helps in practice
Accommodation counts more than compassion. Being able to adjust one's hours on a hard day, to work from home, to stand up and move during a meeting, changes everything. In studies, a PAP (a school support plan, in France) makes it possible to adjust exams and justify absences. At work, the RQTH (official recognition as a worker with a disability, in France) requested from the MDPH (the French departmental disability office) opens up concrete rights, and the simple fact that the team knows in advance avoids having to justify oneself with each episode.

Possible accommodations
Needs change from one day to the next, but a few accommodations help to get through the hard periods.
- At school: a PAP (a school support plan, in France) that allows trips out, postponing a test on a hard day and catch-up after an absence.
- At work: through the RQTH (official recognition as a worker with a disability, in France), flexible hours, working from home on painful days and the option to step away for a break.
- In everyday life: the freedom to postpone without having to justify it, and people nearby who do not play down the pain.

Endometriosis explained to a Child
0–12 years oldThere's a very special lining that covers the inside of the belly of girls and women: it's like a little protective layer. Sometimes, this layer spreads where it shouldn't, a bit like wallpaper sticking to the wrong places in the house.
Every month, when the period comes, this tissue that's in the wrong place bleeds too. That makes little wounds and it becomes very painful, much more than a normal period.
The people who have this feel:
- Very strong pain in the belly or back, especially during their period
- Great tiredness, as if the body were very tired
- Sometimes trouble doing everyday things
It's important: periods should never stop someone from going to school or playing. If they do, it's good to tell a trusted adult.
Endometriosis explained to a Family caregiver
0–99 years oldEndometriosis is tissue that normally lines the inside of the uterus growing elsewhere in the belly, around the organs. Every month, this tissue bleeds like a period, which causes inflammation and pain that is often very intense.
Symptoms that can be a warning sign:
- Periods so painful that they bring everything to a complete halt
- Persistent pain outside of periods (belly, back, legs)
- Fatigue that builds up and settles in for the long term
- Sometimes, difficulty conceiving a child
This is important to know: periods should not bring daily life to a standstill. When they do, it is never normal and it deserves to be taken seriously. You are supporting someone who lives with a reality that is invisible but very demanding. Your patience and your presence have real value.
Endometriosis explained to a Medico-social worker (all ages)
0–99 years oldEndometriosis is a condition in which tissue similar to the lining of the womb develops elsewhere in the abdomen, notably around the organs. Each menstrual cycle causes inflammation and bleeding in these places, generating pain often far more intense than an ordinary period.
The condition works in unpredictable cycles: some days pass with no notable difficulty, while others can make concentration or everyday activities impossible. Chronic tiredness is frequently added to this pain, building up over several years.
As a practitioner, recognising this variable rhythm helps adjust support without asking the person to justify every absence or slowdown. It is a key element in building a consistent partnership between the family, the school or the service.
Endometriosis explained to a Preteen
7–12 years oldEndometriosis is a condition affecting women where tissue grows where it shouldn't, in the belly. Each cycle, it creates very strong pain, sometimes unbearable.
In real life, you might notice:
- very painful periods, that keep her stuck in bed,
- pain outside of periods too,
- great tiredness.
You can help in a really simple way:
- by not pushing her to come when she says no,
- by not saying "it's just your period" in front of others.
Periods aren't supposed to stop you from functioning. When they do, it's not "normal".
Endometriosis explained to a Brother or sister
12–99 years oldEndometriosis: it's tissue that lines the uterus and starts to grow a bit everywhere in the abdomen, where it shouldn't be. Each month, this tissue bleeds like it does inside the uterus, except the blood has nowhere to go. The result: it causes inflammation and often really strong pain.
- Period pain that can keep someone stuck in bed for days
- Pain all year round, not just during periods (stomach, back, legs)
- Fatigue that lingers, building up over months or years
- Sometimes, difficulty getting pregnant
That's why your sister (or your brother supporting her) can be stuck on certain days: periods aren't supposed to knock you out. If they do, there's something to investigate with a doctor.
Endometriosis explained to a Close friend
12–99 years oldEndometriosis is a bit like tissue that normally lines the inside of the uterus starting to grow elsewhere in the abdomen, around the organs. Each month, this "stray" tissue bleeds too, which creates very painful inflammation.
That's why the person can have:
- Periods so painful that they have to stay in bed
- Pain in the stomach, the back or the legs, even outside of periods
- Fatigue that builds up and settles in over years
- Sometimes, difficulty becoming pregnant
The important thing to remember: it's a real condition, not just periods that are "a bit difficult". If she says it's unbearable, she's not exaggerating. And yes, it can truly stop her from doing her normal activities for a few days.
Endometriosis explained to a Teenager
13–17 years oldEndometriosis is when tissue from the uterus grows in the wrong place in the belly. With each cycle, this tissue bleeds too, which causes inflammation and really intense pain.
It can show up as:
- Periods so painful you can't move
- Pain in the belly, the back or the legs, even outside of periods
- Fatigue that builds up over time
- Sometimes difficulties having children later on
Important to remember: periods shouldn't stop you from living your life. If you have pain that seems abnormal to you or that makes daily life hard, it's helpful to talk about it with someone you trust, a parent, a school nurse or a doctor. It's not just about putting up with it, it's about being heard.
Endometriosis explained to a Young adult
18–25 years oldEndometriosis is tissue that lines the uterus and that develops outside its normal place, more or less anywhere in the belly. Each month, this tissue bleeds like a period, but the blood stays trapped inside: it creates inflammation and really disabling pain.
- The symptoms vary: extremely painful periods (to the point of not being able to move), pain outside of periods, chronic fatigue that builds up over time.
- It can also affect fertility, but not always.
- Important to remember: if periods really keep you stuck in bed or impact your daily life, it's not normal and it deserves to be taken seriously. It's a real reason to see a doctor.
Endometriosis explained to a Student
18–25 years oldWhat is endometriosis? It is a condition in which tissue similar to the lining of the womb develops elsewhere in the abdomen, around the organs. Every month this tissue responds to hormones, bleeds and causes inflammation, hence pain far more intense than an ordinary period.
How does it show up day to day? The condition is not stable: on some days it is manageable, on others the pain or the tiredness make it impossible for you to concentrate in class or to attend seminars. This variability is normal and has nothing to do with willpower or motivation.
Your rights on campus. If this concerns you, you can ask for adjustments: extra time in exams, access to a rest room, flexibility on attendance. Contact the accessibility or student health service at your institution, they are there to adapt your environment to your needs, without asking you to "prove" that your request is legitimate.
Endometriosis explained to a Parent
18–99 years oldEndometriosis is when the tissue that lines the inside of the uterus also grows elsewhere in the belly, around the organs. Every month, this tissue bleeds like during a normal period, which causes inflammation and pain.
Signs to know about:
- Very painful periods, sometimes disabling in daily life
- Pain even outside of periods (belly, back, legs)
- Significant fatigue that builds up over time
- Sometimes, difficulty conceiving a child
Important to remember: periods should not bring life to a standstill. If your child or you yourself are in intense pain, it is normal to seek medical help. An early diagnosis and good support make it possible to manage symptoms better day to day.
Endometriosis explained to a Teacher
18–99 years oldEndometriosis affects young girls starting with their first periods. It is a condition that causes very significant pain both during and outside of periods.
In class, you may notice:
- cyclical absences, linked to the menstrual cycle,
- trips to the nurse's office for pain,
- underlying fatigue,
- sometimes shame or silence about the subject.
To make the classroom more inclusive:
- allow trips to the nurse's office without questioning,
- do not comment publicly on the reason for absences.
Endometriosis is underdiagnosed. Simply believing the young girl saves her years of suffering.
Endometriosis explained to a Secondary school teacher
18–99 years oldEndometriosis is a condition in which tissue similar to the lining of the womb develops in other places in the abdomen. Every month, this tissue reacts as it does during a period: it bleeds and becomes inflamed, causing pain often far more intense than an ordinary period.
What makes schooling more complex: the symptoms fluctuate a great deal. On some days the teenager functions normally; on others, pain and tiredness make concentration or even being physically present very difficult. This unpredictable alternation is not "lack of goodwill", but a reality of the rhythm of the condition.
- In class: offer the possibility of stepping out for a few minutes, accept absences during critical periods without repeated justification
- For assessment: consider adjustments (extended time, a quiet place) during peaks of pain
- The main thing: recognising that this variability is medical, not motivational
Endometriosis explained to a University trainer or supervisor
18–99 years oldEndometriosis is a condition in which womb tissue develops outside its normal location, causing inflammation and internal bleeding with each menstrual cycle.
The concrete consequences for a student or trainee are variable and unpredictable:
- Pain that is sometimes intensified, with no direct link to the perceived intensity of an ordinary period
- Variation in energy from one day to the next, independent of the person's will
- Chronic tiredness that builds up over several years
To support accessibility: recognising that this condition creates fluctuating needs for adjustment (occasional remote working, breaks, exam adjustments) allows everyone to prepare their course in good conditions without repeated justification.
Endometriosis explained to a School psychologist
18–99 years oldEndometriosis is a condition in which tissue similar to the lining of the womb develops elsewhere in the abdomen. With each menstrual cycle, this tissue reacts like the womb lining: it bleeds and becomes inflamed, causing pain often far more intense than an ordinary period.
The condition progresses unpredictably: some days pass without particular difficulty, while on other days pain and tiredness make school or professional involvement impossible. This alternation between functional periods and periods of incapacity is characteristic and explains absences or drops in performance that seem inexplicable.
Beyond the cyclical pain, chronic tiredness often sets in over the long term. Knowing this reality makes it possible to understand the students concerned better, without asking for repeated justification, and to adapt support according to the variations in their state.
Endometriosis explained to a Specialized educator
18–99 years oldEndometriosis is a chronic condition in which tissue similar to the lining of the womb develops outside the uterus, notably around other organs. Each menstrual cycle causes inflammation and bleeding in these areas, generating pain often far more intense than that of an ordinary period.
This condition progresses in unpredictable phases: some days pass with no particular discomfort, while others make any activity difficult, even impossible. The chronic tiredness that accompanies it builds up over time and affects concentration and general wellbeing.
As a support professional, recognising this variable rhythm makes it possible to support the person without requiring justification for every episode. This is essential in order to adapt support and maintain trust and inclusion day to day.
Endometriosis explained to a Doctor or healthcare staff
18–99 years oldEndometriosis is characterised by the presence of ectopic womb tissue outside the uterine cavity, mainly in the pelvic cavity. This tissue remains hormone-sensitive and bleeds with each cycle, causing local inflammation, adhesions and pelvic pain often out of proportion to what imaging shows.
The clinical picture is highly variable: some patients present with intense cyclical pain (dysmenorrhoea, dyspareunia, chronic pelvic pain), while others remain asymptomatic despite extensive lesions. This unpredictability makes diagnosis and follow-up more complex.
Frequent functional impacts:
- Limitation of activities during flare-up phases
- Chronic tiredness linked to persistent inflammation
- Impacts on fertility (secondary infertility)
- Psychosocial and occupational repercussions
Possible forms of support: stepwise pain management, hormone therapy (contraceptives, progestogens), multimodal approaches (physiotherapy, relaxation techniques), regular gynaecological follow-up and, in severe cases, surgical options. An approach centred on quality of life and on the patient's empowerment significantly improves the care pathway.
Endometriosis explained to a Medico-social worker
18–99 years oldEndometriosis is a condition in which tissue similar to the lining of the womb develops elsewhere in the abdomen, around the organs. Each menstrual cycle causes inflammation and bleeding in these areas, leading to pain often far more intense than an ordinary period.
The condition works in unpredictable phases: some days pass without particular difficulty, while others make daily life very complicated (concentration affected, mobility reduced). Chronic tiredness is generally added to these fluctuating symptoms.
For your support work: recognising this variable rhythm helps adjust the support without asking the person to justify themselves at every episode. Regular communication with them about their current needs strengthens consistency between the different parties (family, school, services).
Endometriosis explained to a Social worker
18–99 years oldEndometriosis is a condition in which the tissue that normally lines the womb develops elsewhere in the abdomen, around the organs. With each menstrual cycle, this tissue reacts and bleeds, causing inflammation and pain often far more intense than an ordinary period.
The particular feature of this condition: it progresses in unpredictable surges. The person may have days with no apparent problem, then other days when the pain makes work or concentration virtually impossible. Added to this is a chronic tiredness that builds up over time.
As a social worker, recognising this variable nature helps provide better support: absences or fluctuating performance are not a lack of motivation, but a medical reality. People with the condition may benefit from workplace adjustments (remote working, flexible hours) and from social or health support schemes depending on their situation.
Endometriosis explained to a Coworker
18–99 years oldEndometriosis is a condition where uterine tissue grows outside the uterus. At the office, your affected colleague lives with cyclical pain, sometimes very disabling.
You may notice:
- intense pain during periods, sometimes outside of them,
- cyclical absences,
- marked fatigue,
- frequent reluctance to talk about the subject.
To make working together easier:
- accept adjustments (remote work, a day off) without questions,
- never comment along the lines of "it's just a period."
Endometriosis affects around 10% of women. It is a real condition, not a taboo subject.
Endometriosis explained to a Recruiter or HR
18–99 years oldEndometriosis is a condition where tissue similar to the lining of the uterus grows outside its normal location, in the abdomen. This tissue bleeds with each menstrual cycle, causing inflammation and pain that is often very intense.
Symptoms vary from one person to another:
- Disabling menstrual pain that can make being at work impossible on some days
- Chronic pain in the abdomen, back, or legs, even outside of periods
- Persistent fatigue and exhaustion building up over the long term
In a professional setting, common adjustment needs include: flexible hours on certain days of the month, the option of remote work during pain peaks, or adapting physically demanding tasks. The person's skills and overall productivity are not affected by this condition.
Endometriosis explained to a Spouse or partner
18–99 years oldEndometriosis is uterine tissue that grows outside the uterus, a bit everywhere in the abdomen. Each month, this tissue bleeds too, which causes inflammation and often very intense pain.
In practice, this shows up as:
- Periods that are paralysing, where staying in bed is the only option,
- Pain that comes back outside of periods (stomach, back, legs),
- Fatigue that builds up and becomes chronic,
- Sometimes difficulty conceiving.
The important thing to remember: periods shouldn't make someone unable to function. If they do, it's a sign that there's something to investigate seriously.
Endometriosis explained to a Neighbor
18–99 years oldEndometriosis is uterine tissue that grows where it shouldn't, a bit everywhere in the abdomen. Each month, just like during periods, this tissue bleeds too, and that's where the problem comes from: it creates strong inflammation and pain.
People affected may suffer from:
- Extremely painful periods, which truly keep them stuck in bed
- Pain outside of periods (stomach, back, legs)
- Deep fatigue that builds up over time
- Sometimes, difficulty conceiving a child
One important point: periods are never supposed to paralyse someone. If they regularly do, it's usually a sign that there's something to get checked out.
Endometriosis explained to a Activity leader or youth supervisor
18–99 years oldEndometriosis is a condition where uterine tissue grows outside the uterus, in the abdomen. Each month, this tissue bleeds like during normal periods, but stays trapped inside: this creates painful and lasting inflammation.
What you may notice in the person:
- Very intense abdominal or lower-back pain on certain days (not necessarily during periods)
- Fatigue that builds up over time, even after rest
- Absences or moments where they struggle to concentrate or move normally
- They may ask to stop the activity or to sit down without warning
To include them concretely: offer flexible breaks with no questions asked, allow lying-down or seated positions during the activity, don't ask them to "push" if they say no. The pain varies enormously from one day to the next: what they could do last week may be impossible today.
Endometriosis explained to a Adult
26–59 years oldEndometriosis is tissue that normally lines the uterus but grows outside of it, in the abdominal cavity, around the neighbouring organs. Every month, this tissue responds to the hormonal cycle and bleeds, which causes local inflammation.
The consequences can be significant:
- Intense pain during periods, sometimes disabling in daily life
- Chronic pain outside of menstrual periods (belly, lower back, legs)
- Persistent fatigue that builds up over time
- In some cases, difficulty conceiving a child
The key thing to remember: having your period is normal; having it limit your professional or personal life is not. If you recognise this situation, it is helpful to talk to a healthcare professional to understand what is happening and explore the solutions suited to your case.
Endometriosis explained to a Manager or line manager
26–59 years oldEndometriosis is a condition where uterine tissue grows outside the uterus, causing internal bleeding and inflammation with each menstrual cycle. This situation generates pain that is often intense, far beyond simply uncomfortable periods.
The people affected may experience:
- Very strong abdominal and back pain, sometimes disabling
- Chronic fatigue that builds up over several years
- Regular absences or reduced productivity
As a manager, be aware that these symptoms genuinely affect the ability to work. Simple adjustments, such as remote work on certain days, flexible hours, or arranged breaks, allow affected people to keep their job and their quality of life.
Endometriosis explained to a Senior
60–99 years oldEndometriosis is a condition where the tissue that lines the uterus grows elsewhere in the belly, around the organs. Every month, this tissue bleeds too, causing inflammation and pain that can be very intense.
The women affected may experience:
- Periods so painful that they bring everything to a halt
- Pain at other times of the month (belly, lower back, legs)
- Deep fatigue that builds up over the years
- Sometimes difficulty conceiving a child
It is important to know: periods should not bring daily life to a standstill. When the pain becomes disabling, it is a sign that you should talk to a doctor. Solutions exist to relieve the pain and protect independence and quality of life.
Endometriosis explained to a Retiree
60–99 years oldEndometriosis is when tissue from the womb settles elsewhere in the abdomen. With each cycle, this tissue reacts as usual, but causes inflammation and pain far more intense than an ordinary period, it is not "just" a passing discomfort.
The particular feature is that the condition works in surges: on some days everything is fine, on others the pain makes it impossible to do even the simplest activities. The tiredness that builds up can also last for years.
For family and friends, this means understanding that cancellations or moments of rest are not whims, it is an unpredictable reality to be lived with. Staying connected without feeling guilty is what really counts.
