Sickle cell disease
Sickle cell disease is a particularity of the blood passed on from birth. Red blood cells, usually soft and round, sometimes take on a long, rigid shape that slows down circulation. What stands out most about it is how unpredictable it is: a day can go by with nothing visible, then a painful crisis sets in within a few hours, with no warning.
Between crises, the person leads an ordinary life, works, studies, goes out. What weighs on everyday life is mainly the tiredness linked to anaemia and the need to stay protected from the cold, from dehydration and from efforts that are too intense. Knowing these few reference points is often enough to avoid a crisis, without changing anything fundamental in the relationship.
Sometimes a cold draft is enough to set off a crisis. In a person with sickle cell disease, the cold tightens blood vessels that are already fragile, and intense pain can build up within a few hours where, a moment earlier, everything was fine.
This is why a few precautions, keeping a jacket on during a meeting, drinking water regularly, avoiding a long effort in the sun, are far from fussy. The person knows their limits. Those around them do not need to keep watch, just to take these precautions in stride and to know that a crisis can call for a quick response.
A condition that is lived mostly between crises
People often remember sickle cell disease for its painful crises, because they are striking. Yet the essential part plays out between these episodes, in a quiet management of energy and risks. Several realities come back day after day:
- tiredness linked to anaemia, present even when all is well;
- a marked sensitivity to cold, to altitude and to a lack of water;
- regular medical follow-up that sets the rhythm of the year;
- particular attention to infections, especially in childhood.
What helps in practice
Anticipating is better than reacting. Letting the person hydrate freely, accepting that they cover up or take a break, understanding that a crisis is sometimes an emergency: these simple reflexes make a big difference. At school, a PAP (a school support plan, in France) can provide for absences and flexible catch-up. At work, RQTH (official recognition as a worker with a disability, in France) obtained from the MDPH (the French departmental disability office) gives the right to adjusted hours and workstation, without having to explain the situation again to every new contact.

Possible accommodations
Needs vary from one period to another, but a few accommodations come up often.
- At school: a PAP (a school support plan, in France) that allows a water bottle in class, trips to the toilet without justification, and catch-up after an absence for a crisis.
- At work: through the RQTH (official recognition as a worker with a disability, in France), flexible hours, a workstation shielded from the cold and the option to work from home on tiring days.
- In everyday life: what it takes to stay hydrated, to cover up easily, and people nearby who can recognise a crisis and react quickly.

Sickle cell disease explained to a Child
0–12 years oldSickle cell disease is when the red blood cells change shape. Normally, they're all round and they glide everywhere in the blood. With this condition, they become all pointy and stick together, like sticks that get jammed.
When they get jammed, it hurts the person a lot, in the arms, the legs, the belly. It's a real and very strong pain, not exaggerated at all.
People with this condition tire quickly, need to drink lots of water, and don't like the cold. Sometimes, they have to go to the hospital so people can help them.
Sickle cell disease explained to a Family caregiver
0–99 years oldSickle cell disease is an inherited condition that affects the red blood cells. Normally round and flexible, they become elongated and rigid, which can slow down or block blood circulation. It's a complex reality that calls for understanding and patience from those around the person.
The signs can be significant:
- Crises of very intense pain (joints, belly, back), the person doesn't complain lightly, they really are suffering;
- Persistent fatigue linked to anemia, which can make everyday gestures exhausting;
- A particular sensitivity to cold, altitude and dehydration, which calls for simple precautions;
- Sometimes hospital stays during acute crises.
Your role as a caregiver is precious: by staying alert to the signs, helping to keep them well hydrated and supporting them emotionally, you truly contribute to their well-being. Don't hesitate to seek support for yourself too, it's normal that this load is heavy.
Sickle cell disease explained to a Preteen
7–12 years oldSickle cell disease is an inherited condition that deforms the red blood cells. Instead of being round, they become elongated and rigid, which can block circulation and cause very strong pain crises.
In real life, you might notice:
- crises of intense pain (joints, belly, back),
- chronic fatigue linked to anemia,
- sensitivity to cold, to altitude, to lack of water.
You can help in a really simple way:
- by not pushing them to play in the cold or in the cold pool,
- by believing what they say when they're in pain.
The pain of a sickle cell crisis is very intense. They're not being dramatic: they really are in pain.
Sickle cell disease explained to a Brother or sister
12–99 years oldIt's a blood condition that runs in the family. Your brother or sister's red blood cells aren't quite like everyone else's: instead of being round and flexible, they become pointed and rigid, which can block the blood vessels.
The result? Really painful crises can come up without warning, especially in the joints, the stomach or the back. Between crises, they often feel tired because the blood doesn't carry enough oxygen. Cold, altitude or even dehydration can trigger a crisis.
When they say it hurts, you can believe them: it's not exaggerated. A crisis is truly intense. Sometimes a hospital stay is needed for it to pass. It's not bad will or drama: it's simply that their body works differently.
Sickle cell disease explained to a Close friend
12–99 years oldSickle cell disease is an inherited condition that affects the red blood cells in the blood. Normally soft and rounded, they become rigid and elongated, which can slow down or block their circulation around the body.
Here's what you might notice in your friend:
- Crises of very intense pain in the joints, the stomach or the back, it's serious, not an exaggeration
- Regular fatigue because their body works harder to circulate properly
- A particular sensitivity to cold, to altitude, or when they don't drink enough water
- Hospital stays sometimes needed during crises to manage the pain and recover
The key thing: when they tell you they're in pain or that they need to go to hospital, trust them. And outside of crises, it's the same person, keep sharing your moments together as usual, it does them good.
Sickle cell disease explained to a Teenager
13–17 years oldWhat is sickle cell disease? It's an inherited condition that affects the red blood cells (the cells that carry oxygen in the blood). Instead of being round and flexible, they become elongated and rigid, which can block blood vessels.
The consequences day to day:
- Crises of intense pain in the joints, the belly or the back, it's not exaggerated, it really is painful
- Chronic fatigue because the body has fewer red blood cells in good shape
- A particular sensitivity to cold, altitude and dehydration
- Sometimes a need for hospital stays during crises to manage the pain
With a good lifestyle (staying well hydrated, avoiding extreme cold, managing stress) and medical follow-up, people with the condition can live fully. They know their body better than anyone.
Sickle cell disease explained to a Young adult
18–25 years oldSickle cell disease is a genetic condition that affects the red blood cells. Normally soft and round, they become rigid and elongated, which can block circulation and create very intense pain, really intense, not exaggerated at all.
What it involves day to day:
- Crises of severe pain (joints, belly, back) that sometimes call for the hospital
- Regular fatigue linked to anemia
- Triggers to manage: cold, altitude, dehydration
It's inherited, so passed on by the parents. The good news? With medical support, good hydration and a suitable lifestyle, many people live their lives fully, studies, work, personal projects. The important thing is for those around them to understand that the crises are real and that it has to be possible to count on support.
Sickle cell disease explained to a Parent
18–99 years oldSickle cell disease is an inherited condition that affects the red blood cells. Normally round and flexible, they become elongated and rigid, which can slow down the flow of blood and cause very painful crises.
What you may notice in your child:
- Crises of intense pain (joints, belly, back), the pain is real and very significant, not an exaggeration
- Constant fatigue linked to anemia
- A fragility in the face of cold, altitude or dehydration
- Sometimes hospital stays needed during crises
To support your child: keeping them well hydrated, avoiding extreme temperatures, staying alert to the signs of a crisis, and keeping up the medical follow-up. Your presence and your understanding in the face of pain are essential, listen to them, believe them, and don't hesitate to seek medical help when needed.
Sickle cell disease explained to a Teacher
18–99 years oldSickle cell disease is a genetic condition that deforms the red blood cells. It mainly affects children of African, Caribbean and Mediterranean origin, and causes painful crises.
In class, you may notice:
- pain crises, sometimes acute, that may call for hospitalization,
- underlying fatigue,
- sensitivity to cold, to dehydration, to altitude,
- a PAI (an individual care plan agreed with the school, in France) to be aware of.
To make the classroom more inclusive:
- allow water and warm breaks as set out in the PAI,
- believe the child when they report intense pain.
A sickle cell crisis is a medical emergency. The PAI and a fast reaction are the best allies.
Sickle cell disease explained to a Coworker
18–99 years oldSickle cell disease is a genetic condition that deforms the red blood cells. At the office, your affected colleague manages chronic fatigue and a risk of unexpected painful crises.
You may notice:
- absences for crises or hospital stays,
- significant underlying fatigue,
- sensitivity to cold, to dehydration,
- great discretion about the condition.
To make working together easier:
- keep a water bottle always within reach and respect the breaks,
- don't demand physical effort in cold or at altitude.
Sickle cell disease remains poorly known in the workplace. The person's word is enough, no questioning required.
Sickle cell disease explained to a Recruiter or HR
18–99 years oldSickle cell disease is an inherited condition affecting the red blood cells, which lose their soft shape and create blockages in blood circulation.
The main signs include:
- Intense painful crises (joints, abdomen, back), the pain felt is real and significant
- Chronic fatigue linked to anemia
- A sensitivity to certain factors (cold, altitude, dehydration)
- Periods of hospitalization sometimes needed during crises
As a recruiter, keep in mind that people with the condition are perfectly able to hold a job. Simple adjustments (flexibility during crises, access to water, temperature management of the workstation) generally allow for successful integration. Absences linked to crises are predictable and manageable with good communication.
Sickle cell disease explained to a Spouse or partner
18–99 years oldSickle cell disease is an inherited condition where the red blood cells change shape and become rigid. Instead of flowing freely, they pile up in the vessels and block circulation, which causes very painful crises.
What you're going to notice day to day:
- Crises of intense, unpredictable pain (joints, back, abdomen), it's real, not exaggerated
- Constant fatigue, even after rest
- A fragility around cold, altitude, dehydration
- Sometimes hospital stays that can't be avoided
The key thing: during a crisis, your partner is truly suffering. Hydration, warmth, calm and listening without minimising make a real difference. Between crises, a regular, stable rhythm helps them cope better.
Sickle cell disease explained to a Neighbor
18–99 years oldSickle cell disease is an inherited blood condition. The red blood cells change shape and become rigid, which can block circulation and cause very intense pain.
Signs to know:
- Crises of extreme pain (joints, stomach, back) that sometimes need hospital care
- Significant fatigue linked to anaemia
- Sensitivity to cold, to altitude and to dehydration
Good to know: when the person says they're in pain during a crisis, they're truly in a lot of pain. It's an emergency that may call for fast medical care. During a crisis, helping them stay warm and well hydrated does them good.
Sickle cell disease explained to a Activity leader or youth supervisor
18–99 years oldWhat you need to know: sickle cell disease affects the red blood cells, which become rigid and can block blood circulation. This causes unpredictable painful crises, lasting fatigue, and a vulnerability to cold and dehydration.
What you're going to spot:
- Sudden and very intense pain (joints, stomach, back), the person isn't exaggerating, they're truly suffering
- Noticeable fatigue, even without intense effort
- Visible discomfort in the cold, at altitude or when they haven't had enough to drink
How to adapt your activities:
- Ask the person (or their parent/guardian) about their needs: avoiding altitude, easy access to water, the possibility of rest during a crisis
- During a painful crisis: stop the activity, offer a calm and warm spot, contact the family quickly, it's an emergency
- Never push the physical effort; adapt the intensity and plan breaks
- Keep the group inclusive: the person can take part differently, observe or do an adapted task
Sickle cell disease explained to a Adult
26–59 years oldSickle cell disease is a genetic condition that affects the red blood cells. Normally round and flexible, they become elongated and rigid, which can clog the blood vessels and block circulation.
The main signs:
- Crises of extremely intense pain (joints, abdomen, back), the person isn't exaggerating, the pain is real and disabling
- Persistent fatigue linked to chronic anemia
- A particular vulnerability to cold, altitude and dehydration, which can trigger or worsen the crises
- Hospital stays needed during acute crises
Understanding the impact: This inherited condition calls for active management day to day. In a professional or social setting, recognizing the reality of the pain and respecting the need for adaptations (access to water, temperature conditions, rest) is part of working together.
Sickle cell disease explained to a Manager or line manager
26–59 years oldSickle cell disease is an inherited condition that affects the shape of the red blood cells. Instead of circulating freely, these cells become rigid and can block the blood vessels, causing unpredictable painful crises.
The main signs:
- Crises of very intense pain (joints, belly, back), the person can't keep working during these episodes
- Chronic fatigue linked to persistent anemia
- A particular sensitivity to cold, altitude and dehydration
- A need for hospital stays during acute crises
To keep the person in their job: simple adjustments such as access to water, a workstation at a stable temperature, the option of remote work during fragile periods, and flexibility in case of a sudden absence. Clear communication with the person makes it possible to define together the adaptations that suit.
Sickle cell disease explained to a Senior
60–99 years oldSickle cell disease is an inherited condition that affects the red blood cells, making them less supple than they should be. This can sometimes hinder blood circulation and cause difficult moments.
What's helpful to know:
- Crises of very intense pain can occur, especially in the joints or the belly, the person really is suffering, without exaggeration
- Regular fatigue comes with the condition, linked to anemia
- Cold, altitude or dehydration can trigger crises
- During a crisis, a hospital stay may be needed to relieve the pain
With good follow-up and attention to their daily well-being, a person with the condition can lead an active and dignified life. The listening and support of those around them play an important role.
