Kidney failure
Kidney failure means kidneys that filter the blood less and less well. The waste and water the body should be getting rid of build up, which shows as stubborn fatigue, sometimes nausea and rising blood pressure. For a long time nothing shows, which makes the condition hard to explain.
At the most advanced stages, kidney function has to be replaced: dialysis filters the blood in their place, several hours and several times a week, or else a transplant takes over. Between sessions, food and drink are closely managed, and life is organised around these constraints more than the other way round.
Thirst becomes a matter of arithmetic for many people with advanced kidney failure: every glass of water, every soup, every juice-heavy fruit counts toward a daily total that must not be exceeded, because the kidneys no longer clear the surplus. Turning down a coffee or a cold drink isn't a whim, it's a safety rule.
On top of this comes the rhythm of dialysis, which splits the week into before and after each session. People often come out drained, needing time to recover, before the cycle starts again. This alternation is wearing and largely invisible to those around them, who only see the good days.
Invisible fatigue and constraints
Kidney failure often advances without any dramatic sign, then settles into the smallest detail of daily life. Fatigue can't be summoned on command, food is closely watched (salt, potassium, phosphorus, fluids), and medical appointments set the pace of the schedule. None of this can be read on a face.
- fatigue that doesn't ease with rest, especially at the end of the day;
- precise dietary restrictions, hard to keep to during shared meals;
- for people on dialysis, several half-days taken up each week;
- a strong vulnerability to cold, dehydration and infections.
What actually helps
The main support is organisation: being able to fit your obligations around care without having to justify it. RQTH (official recognition as a worker with a disability, in France), obtained through the MDPH (the French disability rights office), makes it possible to adjust the workstation and hours; for a child, a PAP (a personalised support plan at school, in France) or a PPS (an individualised schooling plan, in France) adapts schooling to absences and fatigue.
- flexible hours and dialysis sessions taken into account;
- easy access to water and toilets, without having to ask;
- the chance to catch up on classes or work missed after a session;
- understanding on the days after dialysis, which are often difficult.

- ~ 35.5 millionU.S. adults are estimated to have chronic kidney disease, about 1 in 7.Source: CDC.
- ~ 9 in 10adults with chronic kidney disease do not know they have it.Source: CDC.
- over 3 millionpeople in England live with chronic kidney disease (stages 3 to 5).Source: NHS.
Possible accommodations
Taking the care schedule and the fatigue into account already removes a great deal of pressure.
- At school: put a PAP (a personalised support plan at school, in France) or a PPS (an individualised schooling plan, in France) in place, allow absences for care and catch-up, tolerate trips to the toilet and access to water.
- At work: through RQTH (official recognition as a worker with a disability, in France), ease hours around dialysis, open up remote work on the days after a session, lighten physical tasks.
- In daily life: respect the restrictions on drink and food without pressing, suggest activities that aren't tiring, plan ahead for cold and long journeys.

Kidney failure explained to a Child
0–12 years oldThe kidneys are like the body's little filters. They clean the blood by removing the things we do not want to keep. When they do not filter well, the waste stays in the body, a bit like a bin that does not get emptied.
This makes the person very tired, and they have to be careful about what they eat and drink. Sometimes, they have to go to the hospital several times a week for a machine that does the kidneys' job: this is called dialysis. It takes several hours each time.
It is like having a new rhythm of life: before and after the machine. But the grown-ups and the doctors help the person so that everything goes well.
Kidney failure explained to a Family caregiver
0–99 years oldKidney failure is when the kidneys no longer filter the blood as well as before. The waste the body does not want to keep builds up, and the person often feels very tired, especially towards the end of the day.
Depending on how advanced it is, it may require dialysis sessions, a machine that does the kidneys' job, for several hours, several times a week. It is a rhythm that reshapes all of daily life and also imposes changes in food and drink.
You who support them day to day: this is a demanding role, one that calls for energy and adaptability. Your support truly matters, even in the small gestures. Do not hesitate to seek respite and support for yourself too. Taking care of yourself is also taking care of them.
Kidney failure explained to a Medico-social worker (all ages)
0–99 years oldKidney failure occurs when the kidneys gradually filter the blood less well. The waste and water that the body should remove build up, which causes persistent tiredness, sometimes nausea and a rise in blood pressure.
The particular feature of this condition: it often progresses with no visible symptoms at the start, which makes it hard to explain and to convey to those around or to the child concerned.
At advanced stages, treatment takes up a large place in daily life: dialysis several times a week (several hours per session) or a kidney transplant. Between sessions, food and drink are strictly controlled, and life is organised around these medical constraints.
As a practitioner, you will play a key role in supporting the family and the school in understanding these issues and adapting daily life (schooling, tiredness, dietary constraints, absences for treatment).
Kidney failure explained to a Preteen
7–12 years oldKidney failure is when the kidneys no longer filter the blood as well. Waste builds up, and the body tires more quickly. In the advanced stages, dialysis sessions are needed.
In real life, you might notice:
- significant fatigue, especially at the end of the day,
- restrictions on what is eaten or drunk,
- sometimes dialysis sessions several times a week.
You can help very simply:
- by not insisting that they eat like everyone else,
- by talking to them about something other than the illness.
A dialysis day is not a day like any other: the fatigue that follows can last several hours.
Kidney failure explained to a Brother or sister
12–99 years oldThe kidneys are like filters. Normally, they clean the blood by getting rid of waste and excess water. When they don't work well, the grime builds up in the body, that's kidney failure.
In practice, what does it change day to day?
- Your brother or sister gets tired really fast, especially towards the end of the day
- They have to be careful about what they eat and drink (no chocolate by the handful, no unlimited juice)
- If it's serious, they have to go to the hospital three times a week for dialysis, long sessions that are exhausting
- The whole family schedule revolves around these medical appointments
The important thing to remember: it's not just one more treatment like taking a pill. Dialysis is truly stolen time, the body resting, a big mental load. That explains why they can be irritable, unmotivated or distant sometimes.
Kidney failure explained to a Close friend
12–99 years oldThe kidneys normally filter waste from the blood. When they work less well, this waste builds up and tires the body much faster. It's mostly at the end of the day that your friend may feel this fatigue.
If it's more advanced, they may need dialysis: a machine takes over the kidneys' role for a few hours, several times a week. It's not just one more medical appointment, it's truly time that structures their week, with fixed days and hours.
In practice, you may notice:
- that they take it easier on some days,
- that they're careful about what they eat or drink,
- that their schedule revolves around their sessions.
The secret to carrying on naturally: simply respect their pace, ask without hesitation when you don't know, and show them you're there, fatigue or not.
Kidney failure explained to a Teenager
13–17 years oldWhat are kidneys? They are natural filters that clean your blood by removing waste. When they work less well, this waste builds up and the body tires more quickly.
What does it change day to day? Fatigue at the end of the day, foods to avoid, and sometimes dialysis sessions (a machine that does the kidney's job for several hours) three times a week. It is not just one more appointment: it is a rhythm that really shapes life.
And what about independence? Many people learn to manage their treatment, adapt their routine, and stay active despite it all. It is a challenge, but not impossible. And having friends who understand this different schedule is already a fine form of solidarity.
Kidney failure explained to a Young adult
18–25 years oldKidney failure is when the kidneys filter the blood less well. Normally, they remove waste and excess water, but here, this stuff builds up in the body and it causes intense fatigue, especially towards the end of the day.
It imposes concrete changes: being careful about what you eat and drink, and in the advanced stages, going to dialysis sessions (a machine that does the kidneys' job) three times a week for several hours. It is not just one more treatment, it really shapes daily life.
In practice, life is organised around these sessions: energy, outings, work, everything is planned around them. That is why having kidney failure also means needing flexibility, understanding, and a real network to keep your independence and your participation in life.
Kidney failure explained to a Student
18–25 years oldKidney failure is when the kidneys filter the blood less and less well. As a result, waste builds up in the body, which causes persistent tiredness, sometimes nausea and high blood pressure.
The trap? At the start there are no visible signs. That is why it is a condition that other people do not always understand.
At advanced stages, there are two solutions: dialysis (a machine filters the blood in place of the kidneys, several times a week for hours at a time) or a kidney transplant. Between sessions, food and fluids are strictly controlled.
On campus, adjustments exist: flexible timetables to fit dialysis sessions, access to rest rooms, the possibility of following some classes online, and help in organising your timetable. Do contact the disability service at your institution, making your studies compatible with your situation is exactly their role.
Kidney failure explained to a Parent
18–99 years oldKidney failure means the kidneys no longer filter the blood as well as before. Waste and water build up in the body, which causes significant fatigue and requires keeping a close eye on food and drink.
Day to day, your child may experience:
- Great fatigue, especially at the end of the day, that limits their activities
- Dietary restrictions to follow in order to relieve their kidneys
- If it is advanced: dialysis sessions several hours a week to clean their blood artificially
Dialysis deeply transforms the rhythm of life: it is far more than a simple medical appointment, it is a framework that shapes the whole week. As a parent, your role is to help your child get organised, understand their limits without seeing them as bans, and find moments of lightness despite these constraints.
Kidney failure explained to a Teacher
18–99 years oldKidney failure rarely affects your students, but it may concern a parent or a grandparent. It is a chronic illness that requires heavy follow-up.
On the student's side, you may notice:
- absences for medical accompaniment,
- sometimes taking on responsibility early (dialysis schedule, meals),
- worry behind the smile.
To make the classroom more inclusive:
- take into account absences linked to family appointments,
- open a space to talk without pushing.
A loved one's chronic illness always spills over into a child's daily life. The regularity of school is a support.
Kidney failure explained to a Secondary school teacher
18–99 years oldKidney failure is when the kidneys work less well. Normally, they filter the blood to remove waste and excess water. When they tire, this waste builds up in the body, which causes significant tiredness, sometimes nausea, and can raise blood pressure.
The teaching challenge: for a long time nothing shows from the outside, even though the teenager feels genuinely tired. At more advanced stages, the kidneys can no longer do their work, and dialysis (a machine that filters the blood several times a week) or a transplant becomes necessary.
To adapt this at school: plan flexible timetables if they have dialysis sessions, accept medical absences, allow access to water and to the toilet, and understand that their tiredness is real even if it is not visible. Food and drink also have to be controlled, which calls for working together with the family.
Kidney failure explained to a University trainer or supervisor
18–99 years oldKidney failure is a gradual reduction in the kidneys' capacity to filter the blood and remove waste from the body. This build-up of toxins causes persistent tiredness, sometimes nausea and high blood pressure, often with no visible signs at the early stages.
At advanced stages, regular treatment becomes necessary: dialysis (several sessions a week, several hours each) or a kidney transplant takes over the function of the kidneys. Between sessions, food and fluid intake are strictly controlled.
In a university setting, this means that the student may experience significant tiredness and regular absences linked to treatment, and has to manage dietary constraints. A flexible organisation of classes and exams, along with a suitable rest area, supports their equal access to education.
Kidney failure explained to a School psychologist
18–99 years oldKidney failure occurs when the kidneys gradually lose their capacity to filter waste and water out of the blood. This build-up causes persistent tiredness, sometimes nausea and high blood pressure.
The particular feature of this condition lies in how little it shows at the start: the student may seem to be functioning normally while carrying a significant physiological load, which makes it harder to explain to peers and to adults at school.
At advanced stages, dialysis (treatment lasting several hours, several times a week) or a transplant becomes necessary. Food and fluid intake are strictly controlled, which shapes daily life considerably: an adapted timetable, practical constraints, and sometimes an emotional burden linked to this dependence.
In terms of schooling, this can affect attendance, concentration and the energy available for learning, without the difficulties being obvious at first sight.
Kidney failure explained to a Specialized educator
18–99 years oldKidney failure is a gradual reduction in the kidneys' capacity to filter the blood. Waste and water build up little by little in the body, which can cause persistent tiredness, nausea or a rise in blood pressure.
Silent for a long time, this condition remains invisible and hard to explain day to day. The person may feel tired with no apparent reason, which calls for patience and understanding in providing support.
At advanced stages, the kidneys can no longer do their work: dialysis (a machine that filters the blood) takes over several times a week, or a kidney transplant may be offered. Food and fluid intake then become strictly controlled, which shapes daily life and calls for regular, attentive support in keeping to the medical constraints.
Kidney failure explained to a Doctor or healthcare staff
18–99 years oldKidney failure is a gradual reduction in kidney filtration capacity, leading to a build-up of waste and water in the body. Symptoms are silent or non-specific for a long time: tiredness, nausea, high blood pressure.
Impacts on daily life:
- At advanced stages, replacement treatment becomes necessary (dialysis several times a week or transplantation)
- Strict control of food and fluid intake in order to limit the build-up of residues
- Life is organised around the treatment rather than the other way round
Forms of support: regular nephrological follow-up, nutritional education, psychosocial support in the face of chronic constraints, and coordination with other specialists (cardiology, diabetology depending on associated conditions).
Kidney failure explained to a Medico-social worker
18–99 years oldKidney failure is when the kidneys filter the blood less and less well. The waste and water that the body should remove build up gradually, which causes persistent tiredness, sometimes nausea and high blood pressure.
The main challenge: for a long time, no visible symptom raises the alarm. This discretion makes the condition hard to explain to those around and can make it harder to keep to follow-up measures.
At advanced stages, the kidneys can no longer carry out their function. Dialysis then takes over several times a week for hours at a time, or a kidney transplant is offered. Food and drink become tightly controlled, and the organisation of daily life adapts to these medical constraints rather than the other way round.
Kidney failure explained to a Social worker
18–99 years oldKidney failure is characterised by a gradual decline in how the kidneys work, filtering waste and water out of the body less effectively. The person may experience persistent tiredness, nausea or a rise in blood pressure, often with no visible signs at the start.
At advanced stages, two treatments replace kidney function:
- Dialysis: filtering the blood several times a week, over several hours
- Kidney transplant: transplantation of a donor kidney
These treatments require strict control of food and drink, which strongly shapes daily life. Your support may focus on access to care, practical organisation around dialysis, and social support (invalidity benefits, home help, and so on).
Kidney failure explained to a Coworker
18–99 years oldKidney failure is kidneys that filter less well. In the severe stages, dialysis sessions lasting several hours several times a week are needed.
At the office, you may notice:
- significant fatigue, especially on dialysis days,
- dietary restrictions (salt, potassium, water),
- a precise organisation around the sessions,
- a great deal of discretion about the illness.
To make working together easier:
- respect, without debate, the dialysis schedule and the fatigue that follows,
- do not comment on their food choices during the lunch break.
Dialysis is not one more treatment: it is a life carved up around the sessions.
Kidney failure explained to a Recruiter or HR
18–99 years oldKidney failure is a situation where the kidneys filter waste from the blood less effectively. This waste gradually builds up in the body, which causes significant fatigue, particularly at the end of the day.
Depending on the stage, the person may need regular dialysis sessions (up to three a week, several hours each) to make up for the work the kidneys no longer do. They also have to follow dietary and fluid restrictions.
In a professional context, this means that schedule organisation and breaks can be important issues. With the right adjustments (adapted hours, flexibility around the sessions, access to water and meals), the person can fully exercise their skills.
Kidney failure explained to a Spouse or partner
18–99 years oldThe kidneys normally filter waste from the blood. When they tire, this waste builds up and the body wears out faster. At advanced stages, dialysis is needed, a machine that does the kidneys' work for several hours, three times a week.
Day to day, this means:
- Fatigue that builds up at the end of the day, changing from one day to another
- Foods and drinks to limit or avoid (salt, potassium, phosphorus, liquids)
- Dialysis that structures the week: before, during, after the sessions
- Medical decisions that weigh on the shared organisation
It's a constant balance to find together, not just one more bit of care, but a new pace of life to share.
Kidney failure explained to a Neighbor
18–99 years oldKidney failure is when the kidneys no longer filter the blood as well as before. Waste and water build up in the body, which causes significant fatigue, especially towards the end of the day.
In the most advanced cases, the person has to go through several dialysis sessions a week (a machine that "cleans" the blood in place of the kidneys). It's time spent at the hospital or clinic, several hours in a row.
It also means dietary restrictions: certain foods and drinks have to be avoided. Their whole schedule is organised around these treatments and constraints.
If you cross paths with your neighbour less often or they tell you about fatigue or frequent medical appointments, it's normal: their daily life is truly structured by their treatment.
Kidney failure explained to a Activity leader or youth supervisor
18–99 years oldKidney failure is when the kidneys no longer properly filter waste from the blood. The body gradually clogs up and lasting fatigue sets in. At advanced stages, the person has to go through dialysis sessions (a machine that cleans the blood) several times a week, for several hours.
What you're going to notice:
- Significant fatigue, particularly in the afternoon or at the end of an activity
- Strict dietary restrictions (salt, potassium, phosphorus, liquids), no freedom to improvise at snack time or at the table
- Regular and predictable absences for dialysis, the schedule revolves around these sessions
- Sometimes visible weight gain or swelling after a session
To include them concretely: offer less intensive activities at the end of the day, strictly respect the dietary restrictions (ask the family or the doctor), accept their absences without guilt, and let them adapt the effort to their energy that day. Sitting down for a break is normal.
Kidney failure explained to a Adult
26–59 years oldYour kidneys normally filter the waste from your blood. In the case of kidney failure, this filtering works less well: waste and water build up in your body, which causes persistent fatigue and dietary restrictions.
In the advanced stages, dialysis becomes necessary. It is a machine that takes over from your kidneys for several hours, up to three times a week. It is a treatment that completely reshapes daily life.
- Significant fatigue, especially at the end of the day
- Diet and hydration strictly controlled
- A rhythm of life organised around the treatment sessions
Dialysis is not one treatment among others: it marks a break in personal organisation and calls for concrete, regular adaptation.
Kidney failure explained to a Manager or line manager
26–59 years oldKidney failure is a reduction in the kidneys' ability to filter waste from the blood. This impaired function leads to a build-up of toxins and fatigue that is often significant, particularly at the end of the day.
Depending on the stage of the condition, the person may need dialysis (a treatment that replaces the kidneys' work) several times a week, for several hours. This treatment strongly shapes the schedule and the available energy resources.
Beyond the medical treatment, it also involves strict dietary and fluid restrictions, essential to maintaining health.
As a manager, the challenge is to adapt hours and workloads around dialysis days, plan for sufficient rest periods, and stay attentive to the daily variability of available energy. Flexible and predictable organisation is key to keeping this person in their job over the long term.
Kidney failure explained to a Senior
60–99 years oldKidney failure is when the kidneys filter the blood less effectively than before. Substances that should leave the body build up in it, which causes a particular kind of fatigue, especially at the end of the day.
Depending on the stage, this may require dietary adjustments and, in the advanced stages, dialysis sessions, a treatment that takes over the work the kidneys can no longer do. These sessions, several times a week, call for organisation, but they make it possible to keep living and stay active.
Many people adapt to it over time and keep their plans, their hobbies, and their dignity. The important thing is to be well looked after and to have a medical team that respects your choices and your pace.
Kidney failure explained to a Retiree
60–99 years oldKidneys that work less well, that is the main idea. Normally, they clean the blood by removing waste and excess water. When they tire, these residues build up in your body.
At the start you notice nothing, but gradually there may appear persistent tiredness, nausea, or blood pressure that rises. It is discreet, and that is why many people discover the problem by chance during a medical appointment.
At advanced stages, the work of the kidneys has to be replaced: either by dialysis (a machine that filters the blood several times a week for a few hours), or by a transplant. Life is then organised around these medical appointments and dietary precautions, but people stay active and involved, many carry on with their activities, their hobbies and their connections with family and friends.
The most important thing: good medical follow-up makes it possible to slow the progression and to live well with it.
