Type 1 diabetes
Type 1 diabetes is an autoimmune condition: the immune system destroys the cells in the pancreas that make insulin, the hormone that lets sugar enter the cells. Without insulin supplied from outside, sugar builds up in the blood and the body can no longer function normally.
The person supplies this insulin themselves, by pen or pump, and monitors their blood sugar continuously. It has nothing to do with diet or lifestyle: type 1 often appears in childhood or in young adults, and stays for life.
Eating a simple sandwich is nothing trivial for a person with type 1 diabetes. Before the first bite, you have to estimate the carbohydrates, take into account the planned activity, fatigue and stress, then decide on a dose of insulin. What a pancreas adjusts automatically thousands of times a day, they calculate by hand.
This manual piloting never stops, not at night, not on holiday. A slightly high dose and it is hypoglycaemia: sweating, trembling, blurred vision, an immediate need for sugar to avoid feeling faint. A slightly low dose and blood sugar climbs. Living with type 1 means keeping in mind, at all times, a balance that no one around can see.
Beyond received ideas
Type 1 is not caused by sugar eaten in childhood or by a lack of willpower. It is an autoimmune reaction, unpredictable, that arises with no behavioural cause.
- Insulin is vital and daily, it is not an option or a last resort.
- Hypoglycaemia is an emergency: the person needs fast sugar right away.
- A person in a hypo may seem absent, confused or clumsy, without being at fault.
- The mental load of constant calculation is as tiring as the condition itself.
What helps
The most useful thing is to let the person manage their checks and injections without judging or rushing them, and to know how to react to a hypoglycaemia. At school, a PAP (a personalized support plan at school) or a PPS (an individualized schooling plan) secures meal and monitoring times; at work, breaks and the RQTH (official recognition of disabled-worker status, in France) through the MDPH (the French departmental disability office) make it possible to adapt the role without having to justify oneself constantly.

Possible accommodations
The key is to make possible, without friction, the monitoring gestures and the taking of sugar when needed.
- At school: PAP (a personalized support plan at school) or PPS (an individualized schooling plan) to allow checks, snacks and access to sugar, with a hypoglycaemia protocol known to the team.
- At work: breaks for blood sugar and insulin, flexible hours, RQTH (official recognition of disabled-worker status, in France) through the MDPH (the French departmental disability office) to formalise the accommodations.
- In daily life: keeping sugar within reach, telling those around what to do in case of feeling faint, not dramatising the checks.

Type 1 diabetes explained to a Child
0–12 years oldThe pancreas is a little factory in the belly that normally makes something called insulin. This insulin helps the body use the sugar in food.
In a person with type 1 diabetes, this factory stops working. So the insulin has to come from somewhere else: it gets injected under the skin, like a little prick, several times a day.
It's a bit like the body needs a hand every day to digest sugar properly. The person has to check their blood sugar regularly (with a little prick on the finger) and learn what they can eat, when to play outside, all of this to stay well.
It didn't happen because they ate too much candy: it's just that their body decided to stop on its own. With help from an adult and the right steps, you can live very well with it!
Type 1 diabetes explained to a Family caregiver
0–99 years oldType 1 diabetes is when the pancreas stops producing insulin, the hormone that lets the body regulate sugar in the blood. The person then has to receive this insulin every day, by injection or pump, to stay healthy.
Day to day, this means:
- Regularly checking the sugar level in the blood
- Giving insulin injections, especially at meals
- Paying attention to diet, physical activity and stress, which all affect blood sugar
- Recognizing the signs of a sudden sugar drop and reacting fast with sugar
It's not a matter of lifestyle: it's an autoimmune condition that often appears young and calls for care. As a caregiver, you play a precious role in supporting these daily steps and this vigilance. It's an important responsibility, and it's normal that it feels like a load. Don't hesitate to seek support for yourself too.
Type 1 diabetes explained to a Medico-social worker (all ages)
0–99 years oldType 1 diabetes is a condition in which the immune system damages the cells of the pancreas that produce insulin, a hormone essential for sugar to enter the cells. Without an external supply of insulin, glucose builds up in the blood and the body no longer works properly.
The person has to administer insulin themselves every day (by pen or pump) and monitor their blood sugar level regularly to maintain glycaemic balance.
Important point: this type of diabetes is not linked to diet or lifestyle. It generally appears during childhood or in early adulthood and stays with the person throughout their life. It is a chronic condition that calls for daily management, but is entirely compatible with a normal school, working and social life.
As a practitioner, your role is to support the family and the child or young person in this management, working with the school and the medical team to ensure continuity of care and adaptation of the environment.
Type 1 diabetes explained to a Preteen
7–12 years oldType 1 diabetes is when someone's body no longer makes insulin, the hormone that controls sugar in the blood. The person has to inject it or use a pump every day, and keep an eye on their blood sugar.
In real life, you might notice:
- several injections a day or a sensor on the arm,
- a snack or a sugary drink within reach in case they feel faint,
- constant attention to what they eat.
You can help in a really simple way:
- by never making fun of the injections or the sensor,
- by going to get an adult if you see them pale, sweating or acting strange.
This is not a diabetes "linked to what you eat". It's a condition that often shows up young, and that's managed every single day.
Type 1 diabetes explained to a Brother or sister
12–99 years oldYour brother or sister has a pancreas that no longer makes insulin, the hormone that helps the body use sugar from the blood. So they have to supply it every day, either through injections or with a little pump.
Day to day, that means:
- Checking their blood sugar (the sugar level) several times a day
- Doing insulin injections before eating
- Paying attention to what they eat, to physical activity, to stress, all of that affects blood sugar
- Sometimes having a sudden turn (hypoglycaemia) where they need to take sugar quickly
It's important to know: this isn't something that comes from a bad lifestyle. It's an autoimmune condition, the body turned on itself, and it often shows up young. They'll have to manage it their whole life, but it's manageable with discipline.
Type 1 diabetes explained to a Close friend
12–99 years oldYour friend has a pancreas that no longer produces insulin, the hormone that helps the body regulate sugar in the blood. So they have to inject it regularly, a bit like giving their body a helping hand to do what it can't do on its own anymore.
Day to day, that means:
- Checking their blood sugar (their sugar level) several times a day
- Doing injections before eating
- Staying attentive to what they eat and to their physical activity
- Sometimes having a quick turn (hypoglycaemia) that sorts itself out fast with a little sugar
It's important to know that this isn't linked to their lifestyle, it's a condition that often appears without anyone seeing it coming. With discipline, they manage their daily life very well. You can keep seeing them normally, just being aware that sometimes they'll need to check their sugar or eat at certain times.
Type 1 diabetes explained to a Teenager
13–17 years oldType 1 diabetes is when the pancreas stops producing insulin, a hormone that helps the body use sugar properly. Without it, sugar builds up in the blood, which isn't good.
People with it have to bring in insulin from outside every day, by injection or pump, and regularly check their blood sugar level. It's a bit like your pancreas needs a constant helping hand.
Day to day, this means: managing your meals, watching your physical activity, and staying alert to keep your sugar level from going too high or too low. Sometimes a fast drop (hypoglycemia) can make you feel faint, and you need to take sugar quickly.
It's important to know: it's not the person's fault, it's not linked to lifestyle or to what you eat. It's an autoimmune condition that can appear young, and it takes organization, but plenty of people live with it without any problem.
Type 1 diabetes explained to a Young adult
18–25 years oldType 1 diabetes is when the pancreas no longer produces insulin, the hormone that helps the body regulate sugar in the blood. Contrary to common belief, it isn't linked to diet or lifestyle: it's an autoimmune condition that often appears in young people.
Day to day, this means:
- Supplying insulin every day (by injection or pump)
- Checking your blood sugar several times a day
- Adapting your diet, physical activity and sleep
- Staying alert to faint spells (hypoglycemia) that can happen suddenly and need fast-acting sugar
Yes, it's constant and careful management, but with good organization, people with type 1 diabetes live fully and take part in all activities. It's mostly a matter of learning and gradual independence.
Type 1 diabetes explained to a Student
18–25 years oldType 1 diabetes is when the body's immune system destroys the cells of the pancreas that produce insulin, the hormone needed for sugar to enter the cells. Without it, sugar builds up in the blood and the body does not work properly.
Contrary to received ideas, it is not linked to diet or lifestyle, it is an autoimmune condition that often appears in young adults and stays for life.
People with the condition inject insulin themselves (with a pen or a pump) and monitor their blood sugar regularly. On campus, they may need adjustments: access to a quiet place for injections, permission to eat or drink in class, permission to check their glucose sensor during exams.
- Contact your student disability service to set up these adjustments
- If this concerns you, let your lecturers know discreetly, they will understand your needs better
Type 1 diabetes explained to a Parent
18–99 years oldType 1 diabetes is a condition where the pancreas no longer makes insulin, the hormone that controls the sugar level in the blood. Your child will need to receive insulin every day, by injection or pump, to make up for it.
Day to day, this means:
- Checking the blood sugar level several times a day
- Giving insulin injections, especially before meals
- Paying attention to diet, physical activity and stress, which all affect this level
- Recognizing and quickly handling faint spells (hypoglycemia) by giving sugar
Important to know: it isn't linked to lifestyle, it's an autoimmune condition that often appears in children and young people. With care and the right support, your child can live normally and do the activities they enjoy.
Type 1 diabetes explained to a Teacher
18–99 years oldType 1 diabetes is a pancreas that no longer makes insulin. The child with diabetes has to supply it themselves, by injection or pump, and monitor their blood sugar constantly.
In class, you may notice:
- several blood sugar checks each day,
- insulin injections before meals,
- sometimes faint spells (hypoglycemia) that call for sugar,
- a precise PAI (an individual care plan agreed with the school, in France) to be aware of.
To make the classroom more inclusive:
- allow snacks, drinks and bathroom breaks as set out in the PAI,
- don't comment on the equipment in class (sensor, pump, reader).
Diabetes is not a whim or a fault. It's a real autoimmune condition.
Type 1 diabetes explained to a Secondary school teacher
18–99 years oldType 1 diabetes is a condition in which the body no longer produces insulin, a hormone essential for the sugar from food to enter the cells. It is a malfunction of the immune system, not linked to diet or lifestyle.
The teenager has to inject insulin themselves several times a day (with a pen or a pump) and regularly check their blood sugar level. It is a daily management task, but it allows a normal life and schooling without restriction.
In class, a few simple adjustments make learning easier: allowing access to water and to the toilet, planning breaks for taking insulin or checking blood sugar, and tolerating a snack if needed. The student becomes independent in managing this and learns to adapt to their needs.
Type 1 diabetes explained to a University trainer or supervisor
18–99 years oldType 1 diabetes is an autoimmune condition: the person's immune system damages the cells of the pancreas that produce insulin, the hormone that allows cells to use blood sugar. Without an external supply of insulin, glucose builds up in the blood and the body cannot work properly.
The person has to inject insulin themselves regularly (by pen or pump) and monitor their blood sugar continuously to maintain their metabolic balance. Contrary to received ideas, this condition is linked neither to diet nor to lifestyle: it generally appears in childhood or in young adults and stays with the person for life.
To foster inclusion in education, it is important to allow access to discreet spaces for blood-sugar measurements, to adapt break times if needed, and to recognise that this daily management requires independence but does not limit intellectual or professional abilities.
Type 1 diabetes explained to a School psychologist
18–99 years oldType 1 diabetes is a condition in which the immune system damages the cells of the pancreas that produce insulin, the hormone that allows cells to use blood sugar. Without this regulation, glucose builds up in the blood and the body cannot work properly.
The person has to supply the insulin themselves, via a pen or a pump, and monitor their blood sugar regularly. It is a daily management task that calls for attention and discipline, but which allows an entirely normal life.
Important to remember: it is not linked to diet or lifestyle habits. It generally appears in childhood or in young adults and stays with the person for life. For a student concerned, the psychological issue may involve adapting to this management load, accepting a visible difference, and self-confidence in learning and in social interaction.
Type 1 diabetes explained to a Specialized educator
18–99 years oldType 1 diabetes is a condition in which the immune system prevents the pancreas from producing insulin, the hormone needed for sugar to enter the cells. Without an external supply of insulin, sugar builds up in the blood and the body does not work properly.
The person has to administer insulin themselves every day, via a pen or a pump, and monitor their blood sugar level regularly. It is a condition that stays for life, with no link to diet or lifestyle.
This diagnosis, often made in childhood or in young adults, calls for learning and adaptation, but allows full inclusion in mainstream settings with regular support and a good knowledge of the routines to master.
Type 1 diabetes explained to a Doctor or healthcare staff
18–99 years oldType 1 diabetes is an autoimmune condition in which the immune system progressively destroys the insulin-producing beta cells of the pancreas. The result is an absolute insulin deficiency, unlike type 2.
Metabolic consequences: without an exogenous supply of insulin, glucose builds up in the bloodstream, causing chronic hyperglycaemia and leaving cellular metabolism unable to function properly.
Management required: the person has to administer insulin daily (pen injections or pump infusion) and ensure regular blood-sugar monitoring, often continuously via sensors. Adherence is decisive in preventing complications.
Epidemiological features: typically occurring in childhood or in young adults, independently of diet or lifestyle. It is a chronic condition that lasts a lifetime.
Forms of support: therapeutic education, regular endocrinological follow-up, psychosocial support and coordination with the other health professionals are essential in order to optimise blood-sugar balance and prevent microvascular and macrovascular complications.
Type 1 diabetes explained to a Medico-social worker
18–99 years oldType 1 diabetes is a condition in which the immune system damages the cells of the pancreas that produce insulin, the hormone needed for sugar to enter the cells and be used by the body.
Without an external supply of insulin, sugar builds up in the blood and the body cannot work properly. The person therefore has to inject insulin regularly themselves (by pen or pump) and monitor their blood sugar level.
Important point: it is not linked to diet or lifestyle, it is an autoimmune condition that often appears in childhood or adolescence and stays with the person throughout their life. Your role is to support the setting up of self-management routines and to coordinate with the family and the school to ensure continuity of care.
Type 1 diabetes explained to a Social worker
18–99 years oldType 1 diabetes is a condition in which the person's immune system damages the cells of the pancreas that produce insulin, the hormone essential for regulating blood sugar. Without an external supply of insulin, sugar builds up in the body and creates difficulties in how it works.
Contrary to received ideas, it is not linked to diet or lifestyle. The person has to inject insulin themselves every day (with a pen or a pump) and monitor their blood sugar level regularly.
It is a lifelong condition: it generally appears in childhood or in young adults and calls for continuous follow-up. In your administrative support work, you can refer people to the health insurance system for reimbursed medical devices, associations such as France Diabète (a French diabetes association) for peer support, or the departmental disability offices for suitable support.
Type 1 diabetes explained to a Coworker
18–99 years oldType 1 diabetes is a pancreas that no longer makes insulin. At the office, your colleague with type 1 diabetes does their own chemical regulation every single day.
You may notice:
- several blood sugar checks over the course of the day,
- insulin injections or a pump worn on the body,
- sometimes hypoglycemic spells that need fast-acting sugar,
- precise scheduling of meals and breaks.
To make working together easier:
- don't push back a meal break without a strong reason,
- let them have a drink or a snack in a meeting without comment.
Type 1 diabetes is not the "sugar" diabetes. It appears young, with no behavioral cause.
Type 1 diabetes explained to a Recruiter or HR
18–99 years oldType 1 diabetes is an autoimmune condition where the pancreas no longer produces insulin, the hormone that regulates blood glucose. The person has to self-inject insulin daily (by injection or pump) and regularly monitor their blood sugar level.
At work, in concrete terms this involves:
- Blood sugar checks several times a day
- Insulin injections, usually around mealtimes
- Attention to diet, physical activity and stress
- Occasionally, faint spells (hypoglycemia) needing a quick intake of sugar
It isn't linked to lifestyle, but to an immune dysfunction. With suitable adjustments, a break for injections, access to snacks, flexibility when needed, candidates with type 1 diabetes work without limits in most jobs.
Type 1 diabetes explained to a Spouse or partner
18–99 years oldYour partner has a pancreas that no longer produces insulin, the hormone that regulates sugar in the blood. So they have to inject it daily (or use a pump) and constantly monitor their blood sugar.
Day to day, that means several checks per day, injections before meals, and regular attention to food, physical activity and stress. Sometimes hypoglycaemia happens suddenly: then fast-acting sugar is needed to bring the level back up.
It's an autoimmune condition, not linked to lifestyle. It often sets in young and is managed with discipline, for life. For the two of you, that means knowing the warning signs, keeping sugar within reach, and helping them keep the routine without overloading them.
Type 1 diabetes explained to a Neighbor
18–99 years oldType 1 diabetes is when the pancreas no longer makes insulin, the hormone that regulates sugar in the blood. So the person has to inject insulin daily and regularly check their sugar level.
It's an autoimmune condition, not linked to lifestyle, which often appears young and calls for constant vigilance: attention to food, to physical activity, and keeping up with injections.
Good to know in case of a turn: sometimes the person can have a sudden drop in sugar (hypoglycaemia). They may seem confused, shaky or tired. In that case, a little fast-acting sugar (a sugar cube, juice, a sweet) quickly helps them recover.
Type 1 diabetes explained to a Activity leader or youth supervisor
18–99 years oldWhat does type 1 diabetes mean for you as a group leader?
It's a condition where the pancreas no longer produces insulin (the hormone that regulates blood sugar). The person has to inject insulin every day and constantly monitor their blood sugar level. It's not linked to lifestyle: it's an autoimmune condition, often diagnosed young, that calls for very regular management.
What changes concretely in your activities:
- Signs to know: sudden fatigue, shaking, sweating, irritability or confusion = a possible drop in blood sugar. You then need to give fast-acting sugar quickly (juice, a sweet, a biscuit) and alert an adult.
- Timing and meals: the activity has to respect meal and injection times. Let the person know about any change in timing or physical intensity.
- Inclusion is simple: no activity is off limits. The person manages their diabetes and takes part normally. Just stay attentive and available if there's a problem.
- To keep nearby: fast-acting sugar, an emergency number, contact details for those in charge. Let them stay independent in their own management (injections, checks).
Type 1 diabetes explained to a Adult
26–59 years oldType 1 diabetes is an autoimmune condition: the pancreas stops producing insulin, the hormone that regulates the sugar level in the blood. So the person has to inject insulin every day to keep their blood sugar balanced.
Day to day, this involves active management:
- Several blood sugar readings a day to know the sugar level
- Insulin injections, especially before meals
- Constant attention to diet, physical activity and stress, which all affect blood sugar
- Vigilance toward hypoglycemia (sudden drops in blood sugar), which calls for fast action
It isn't a consequence of lifestyle, but a condition that calls for regular, structured care throughout life. With good organization, most people lead a completely normal life.
Type 1 diabetes explained to a Manager or line manager
26–59 years oldType 1 diabetes is an autoimmune condition: the pancreas no longer produces insulin, the hormone that regulates the sugar level in the blood. The person has to supply it every day by injection or pump, and regularly monitor their blood sugar.
At work, this means your team member will need:
- Access to moments to check their blood sugar several times a day
- The possibility of eating at regular times
- A discreet space for their insulin injections if they wish
- To be able to react quickly in case of a hypoglycemic spell (sugar needed immediately at hand)
With good balance and these small adjustments, day-to-day management becomes a routine. It's a matter of organization rather than limitation, and your support with these simple adaptations makes all the difference in keeping someone engaged and performing.
Type 1 diabetes explained to a Senior
60–99 years oldType 1 diabetes is a situation where the pancreas no longer produces enough insulin, the hormone that helps the body use sugar. It's a condition that isn't linked to lifestyle, but to a particular way the immune system works.
People with it have to learn to manage their blood sugar day to day: regularly checking their sugar level, injecting insulin, and adapting their diet and physical activity. It's a kind of discipline that takes organization, but that lets you live fully.
With a good understanding of their situation and today's tools (injections, pumps, modern readers), everyone can keep their independence and maintain the activities that matter to them. It's a condition to manage, not a limit to who you are.
Type 1 diabetes explained to a Retiree
60–99 years oldType 1 diabetes is a situation in which the pancreas, the organ that makes insulin, can no longer do so. Insulin is simply the key that lets sugar into the cells to feed them. Without it, sugar builds up in the blood and that tires the body.
What you need to know: it is not linked to what we eat or to our lifestyle, it is a reaction of the immune system that often appears early in life and lasts for life. The person has to supply the insulin themselves, with a pen or a pump, and monitors their sugar level regularly.
Well managed, this condition does not prevent anyone from staying active, seeing friends, travelling or carrying on with their activities. It is simply a balance to find day by day.
