Cushing Syndrome in Children: Symptoms, Causes, and Treatment

Cushing syndrome is a condition that happens when the body has too much cortisol, a hormone made by the adrenal glands. This problem is uncommon in children, but when it does occur it can affect growth, weight, mood, and overall health.

This guide explains Cushing syndrome in clear, family-friendly language so you can better understand your child’s condition, work with the medical team, and support your child at home.

What Is Cortisol and Why Does It Matter?

Cortisol is often called the body’s “stress hormone.” It helps with:

• Managing the body’s response to stress and illness
• Keeping blood sugar in a safe range
• Controlling blood pressure
• Helping the body use protein, fat, and carbohydrates for energy
• Keeping inflammation in check

Cortisol is produced by the adrenal glands, which sit on top of each kidney. The pituitary gland in the brain sends a hormone called ACTH (adrenocorticotropic hormone) that tells the adrenal glands how much cortisol to make.

In Cushing syndrome, this system gets out of balance and the body is exposed to high cortisol levels for a long time. That long-term exposure is what leads to the symptoms.

Types and Main Causes of Cushing Syndrome in Kids

Doctors usually divide Cushing syndrome into two big groups based on where the extra cortisol comes from.

In children, both medication-related Cushing syndrome and hormone-producing tumors are seen, but overall the condition is rare.

Why Steroid Medicines Can Cause Cushing Syndrome

Many children need glucocorticoid (steroid) medicines to control serious illnesses such as asthma, autoimmune conditions, inflammatory bowel disease, or certain cancers. These medicines act like cortisol in the body and can be lifesaving.

Problems arise when a child:

• Needs high doses of steroids
• Takes them for a long time (months or years)
• Receives strong steroid injections or repeated bursts of oral steroids

Over time, the body reacts as if cortisol levels are too high, and Cushing syndrome may develop. Doctors balance the benefits of these medicines against the risk of side effects and will try to use the smallest effective dose.

Common Signs and Symptoms in Children

Not every child will have the same symptoms, and they may appear gradually. Many features also overlap with more common problems such as weight gain or puberty, which can make early diagnosis challenging.

Physical Changes Parents Often Notice

• Weight gain, especially around the trunk and upper body
• Rounded, puffy face (often called a “moon face”)
• More fat on the upper back or between the shoulders (sometimes called a “buffalo hump”)
• Arms and legs that look relatively thin compared with the body
• Slowed growth in height despite weight gain, so a child becomes shorter and heavier than peers
• Thin, fragile skin that bruises easily and heals slowly
• Pink, red, or purple stretch marks (striae), especially on the belly, thighs, breasts, or upper arms
• Acne or oily skin and sometimes increased body or facial hair (more common in teens)

Health Problems Linked to High Cortisol

• High blood pressure
• High blood sugar or new-onset diabetes
• Weak bones (osteoporosis) and higher risk of fractures
• Muscle weakness, especially in the upper arms and thighs
• Frequent infections or slow recovery from illnesses because cortisol dampens the immune system

Emotional and Behavioral Changes

• Mood swings, irritability, or unusual anger
• Sadness or depression
• Trouble sleeping or daytime tiredness
• Difficulty concentrating at school

Puberty and Reproductive Symptoms (Mostly in Older Children)

• Irregular or absent menstrual periods in girls
• Decreased growth of facial or body hair in boys
• Reduced interest in puberty-related changes overall

If several of these changes appear together over months, especially weight gain with slowed height growth and a rounded face, doctors may suspect Cushing syndrome.

When to Call the Doctor

Contact your child’s healthcare provider if you notice:

• Rapid weight gain with little or no height increase
• Unusual stretch marks on the skin
• Severe acne, easy bruising, or very thin skin
• Blood pressure readings that are repeatedly high for your child’s age
• Long-term use of steroid medicines plus any of the above signs

If your child takes steroid medicine, never change the dose or stop it suddenly on your own. Always speak with the prescribing clinician first—sudden withdrawal can be dangerous because the body may not be ready to make enough cortisol on its own.

How Doctors Diagnose Cushing Syndrome

Diagnosing Cushing syndrome usually happens in stages and is often led by a pediatric endocrinologist (a hormone specialist for children).

1. Medical History and Physical Exam

The doctor will ask about:

• All current and past medicines, especially steroid drugs
• Timeline of weight, height, and puberty changes
• Other health conditions, such as asthma or autoimmune disease
• Family history of hormone or adrenal problems

They will also check growth charts, blood pressure, skin changes, and body proportions.

2. Hormone Testing

Several tests may be used to confirm too much cortisol:

• Late-night saliva or blood cortisol – cortisol is normally lowest at night; high levels then are suspicious.
• 24-hour urine free cortisol – measures the amount of cortisol released into urine over a full day.
• Low-dose dexamethasone suppression test – the child takes a small steroid pill; in healthy people this lowers cortisol levels, but in Cushing syndrome it often does not.

Often, doctors repeat tests to be certain, because cortisol levels can vary from day to day.

3. Finding the Source of Extra Cortisol

Once high cortisol is confirmed, the next step is figuring out where it is coming from:

• ACTH blood test – helps determine whether the extra cortisol is driven by ACTH or is ACTH-independent.
• Imaging tests – such as MRI of the pituitary gland or CT/MRI of the adrenal glands to look for tumors or overgrowth.
• In rare, complex cases, specialized sampling of veins near the pituitary or adrenal glands to pinpoint hormone production.

Treatment Options for Children

The main goal of treatment is to bring cortisol levels back to normal while protecting your child’s growth and long-term health. The specific plan depends on the cause.

If Steroid Medicines Are the Cause

• The doctor may gradually reduce the steroid dose.
• When possible, they may switch to a different medicine with fewer cortisol-like effects.
• Sometimes, they try to use local treatments (like inhalers or creams) instead of high-dose pills or injections.

Steroid doses are always lowered slowly to give the adrenal glands time to “wake up” and start making cortisol again on their own.

If a Tumor or Adrenal Overgrowth Is the Cause

• Surgery is often the first-line treatment to remove a pituitary or adrenal tumor when possible.
• If surgery does not remove all tumor tissue or cannot be done safely, radiation therapy may be used, especially for pituitary tumors.
• In rare cases, both adrenal glands may need to be removed; this cures the cortisol excess but requires lifelong hormone replacement.

Medicines That Lower Cortisol

Sometimes, doctors prescribe medicines that either reduce cortisol production or block its effects while waiting for surgery to work or when surgery is not possible. These may include drugs such as ketoconazole, metyrapone, or others that act on adrenal hormone production.

Your child may also need separate treatment for related problems like high blood pressure, diabetes, or weak bones until cortisol levels improve.[10]

Life After Treatment: What Parents Can Expect

Recovery from Cushing syndrome is usually a gradual process. Many children begin to feel better within months of successful treatment, but some effects can take longer to reverse.

Short-Term Changes After Cortisol Normalizes

• Weight may slowly decrease or redistribute in a healthier way.
• Energy levels and muscle strength often improve.
• Blood pressure and blood sugar frequently return toward normal ranges.
• Mood swings and sleep problems usually ease.

Growth and Puberty

Many parents worry most about growth. After treatment:

• Some children experience a “catch-up” phase in height.
• Others may not fully reach their genetically expected adult height, depending on how long cortisol was high and how early treatment started.
• Puberty may restart or proceed more normally once hormones stabilize.

Regular visits with the endocrinology team allow close monitoring of growth, puberty, and hormone levels.

Long-Term Outlook

Many children treated for Cushing syndrome go on to live active, healthy lives. Long-term follow-up is still important because:

• Tumors can sometimes come back, even years later.
• Some children may have lasting issues with bone density or metabolism.
• If both adrenal glands were removed, your child will need lifelong hormone replacement and emergency steroid plans during illness or injury.

Supporting Your Child at Home

Parents and caregivers play a key role in helping a child cope with Cushing syndrome and its treatment.

Everyday Care Tips

• Follow the medication schedule exactly as prescribed.
• Keep a written list of all medicines and doses.
• Attend all follow-up appointments and bring growth charts or notes about symptoms.
• Ask the care team how to handle steroids during illness, surgery, or injury if your child is on replacement therapy.

Nutrition and Physical Activity

Cortisol excess often leads to weight gain and muscle weakness, so lifestyle habits matter:

• Offer balanced meals with plenty of fruits, vegetables, whole grains, and lean protein.
• Limit sugary drinks and heavily processed snacks.
• Encourage gentle, age-appropriate exercise—like walking, swimming, or biking—as your child’s doctor allows.
• Ask about bone-strengthening activities and whether your child needs extra vitamin D or calcium.

Emotional and Social Support

• Talk openly with your child about the condition using age-appropriate language.
• Validate feelings about body changes, scars, or time missed from school.
• Work with school staff to arrange any needed supports or accommodations.
• Consider counseling if your child shows ongoing sadness, anxiety, or social withdrawal.
