Addison’s disease is a rare and chronic endocrine condition that results from the adrenal glands failing to produce enough of the life-sustaining hormones cortisol and aldosterone. While the condition is most frequently diagnosed in adults between the ages of thirty and fifty, it can and does affect children and young people. In the pediatric population, the disease presents unique challenges, as the symptoms can be easily confused with common childhood illnesses or growth-related changes. Because children have different physiological needs for hormone replacement and are at a higher risk of complications like low blood sugar, the management of the condition in younger patients requires a specialized approach led by pediatric endocrinologists.

Prevalence and Age of Onset in Children
While Addison’s disease is primarily considered an adult-onset condition, it is estimated to affect approximately one in ten thousand children in the United Kingdom. In adults, the peak age for diagnosis typically falls between the ages of thirty and fifty, with women being diagnosed significantly more often than men. In the pediatric population, the demographics shift slightly, as some studies suggest that boys may represent up to seventy percent of cases diagnosed during childhood. This shift is often attributed to specific genetic causes that primarily affect males, such as X-linked adrenoleukodystrophy.
Although the incidence is lower in children than in adults, the impact on a developing body is profound. Adrenal insufficiency in a young person is a life-long condition that requires consistent medical oversight to ensure that hormone replacement levels support normal physical growth and brain development. Most pediatric cases are diagnosed after a period of vague and non-specific symptoms that may have been present for weeks or even months. The rarity of the condition in children often means that it is not the first possibility a doctor considers, which is why a high level of clinical awareness is necessary for timely intervention.
Unique Symptoms in Pediatric Patients
While both adults and children share common symptoms like extreme fatigue, salt cravings, and darkening of the skin, children often exhibit signs that are specific to their stage of development. One of the most critical unique symptoms in children is hypoglycemia, or low blood sugar. While adults with Addison’s disease can experience low blood sugar, it is much more frequent and dangerous in infants and young children. This is because children have smaller glucose reserves and a higher metabolic rate, making them more sensitive to the loss of cortisol, which normally helps maintain stable sugar levels.
Faltering growth and delayed puberty are also significant indicators of adrenal insufficiency in young people. Because the body is under constant physiological stress from the lack of hormones, it may not have the resources to support a normal growth spurt or the onset of sexual development. Parents may notice that their child is smaller than their peers or has stopped gaining weight unexpectedly. In teenage girls, the condition can sometimes be misdiagnosed as an eating disorder because of the combination of weight loss, nausea, and poor appetite.
The Challenge of Delayed Diagnosis in Teens
Diagnosis in adolescents can be particularly difficult because many of the symptoms of Addison’s disease mimic the natural changes and challenges of puberty. Tiredness, mood swings, and a desire to sleep more are often dismissed as normal teenage behavior. However, when these symptoms are accompanied by a distinctive darkening of the skin, especially on the knuckles, scars, or inside the mouth, it should raise clinical suspicion. This darkening is caused by the pituitary gland overproducing a hormone called ACTH in a futile attempt to stimulate the failing adrenal glands.
The NHS information on Addison’s disease notes that the onset is often so gradual that the patient and their family may not notice the changes until a crisis occurs. For a teenager, the emotional impact of a chronic diagnosis can also be substantial. They may feel different from their peers or struggle with the responsibility of taking medication multiple times a day. If the diagnosis is missed, the patient is at a high risk of an adrenal crisis during periods of exam stress, sporting events, or common infections, which can be life-threatening if not treated immediately.
Management and Safety in School Settings
For a child with Addison’s disease, school life requires careful planning and coordination between parents, teachers, and medical teams. Because the body cannot produce its own cortisol, the child must take replacement steroids at specific times throughout the day, including during school hours. Every child with the condition in the UK should have an Individual Healthcare Plan (IHP) that outlines their medication schedule and what to do in an emergency. This plan is essential for ensuring that the school staff understands the urgency of the situation if the child becomes unwell.
Schools are required to keep an emergency hydrocortisone injection kit on-site for any child with adrenal insufficiency. This kit is intended for use if the child experiences a severe accident or a vomiting bug where they cannot keep their oral medication down. The NICE guidelines on adrenal insufficiency emphasize that all children and their caregivers should be trained in how to use these emergency tools. While the child is at school, they should also wear a medical alert bracelet or carry a steroid alert card to ensure that any paramedics or first aiders are aware of their condition in the event of an emergency.
| Age Group | Common Primary Causes | Key Symptom Focus |
| Infants/Toddlers | Congenital Adrenal Hyperplasia | Hypoglycemia, poor weight gain |
| Children (5 to 12) | CAH, Autoimmune issues | Growth delay, salt cravings |
| Adolescents | Autoimmune, X-linked ALD | Fatigue, delayed puberty, skin changes |
| Adults (30 to 50) | Autoimmune Adrenalitis | Weight loss, low blood pressure, pigment |
Transitioning to Adult Specialist Care
As a young person with Addison’s disease approaches adulthood, their care must be transitioned from a pediatric setting to an adult endocrinology department. This transition typically happens between the ages of sixteen and eighteen and is a critical period for ensuring that the patient takes full responsibility for their own health. In a pediatric setting, parents often manage the medications and appointments, but adult care requires the patient to be self-sufficient in recognizing their own symptoms and managing their “sick day rules.”
The transition process usually involves several joint appointments where both the pediatric and adult teams are present. This allows the new medical team to understand the patient’s history while providing the young person with the confidence to navigate the adult healthcare system. During this time, the doses of medication may be adjusted to reflect the patient’s adult body weight and lifestyle. Ensuring a smooth transition is vital for preventing gaps in care that could lead to an adrenal crisis during the early years of adulthood.
Conclusion
Addison’s disease can affect people of any age, including infants, children, and teenagers, although the causes and symptoms often differ from those seen in adults. While adults are more likely to develop the condition through an autoimmune process, children are frequently affected by genetic conditions like Congenital Adrenal Hyperplasia. Managing the condition in young people requires a focus on growth, development, and safety within educational settings. With appropriate hormone replacement therapy and careful monitoring by a pediatric specialist, children with Addison’s disease can lead full, active lives and enjoy a normal life expectancy. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Is Addison’s disease more dangerous for children than adults?
It can be more dangerous because children are more prone to rapid dehydration and life-threatening low blood sugar during an illness.
Can a child with Addison’s play competitive sports?
Yes, most children can participate in sports, though they may need to adjust their medication dosage before intense physical activity.
Do children always need an injection kit at school?
Yes, it is a standard safety requirement in the UK to have an emergency hydrocortisone kit available at all times in the school setting.
Will my child grow normally with this condition?
With correct and consistent hormone replacement therapy, most children with Addison’s disease will achieve a normal final height.
How often does a child with the condition need a check-up?
Children typically see a pediatric endocrinologist every three to six months to monitor their growth and adjust medication doses.
Can Addison’s disease be mistaken for a stomach bug in children?
Yes, the early stages of an adrenal crisis include vomiting and tummy pain, which can be easily confused with a common gastric infection.
Are there support groups for parents of children with Addison’s?
Yes, organizations like the Addison’s Disease Self-Help Group provide specific resources and forums for families in the United Kingdom
