Growth Hormone Deficiency in Children: Symptoms, Diagnosis, and Treatment

Medically Reviewed by Dr Devin Stone ND Updated: 05/31/2026

What Is Growth Hormone Deficiency?

Growth Hormone Deficiency (GHD) is a medical condition in which a child does not produce enough growth hormone to support normal growth and development.

Growth hormone is produced by the pituitary gland, a small gland located at the base of the brain. This hormone plays a critical role in helping children grow taller, develop healthy bones and muscles, and maintain normal metabolism throughout childhood.

When growth hormone levels are too low, children often grow significantly slower than expected for their age.

Growth Hormone Deficiency can occur at birth (congenital) or develop later in childhood (acquired). While relatively uncommon, it is one of the most important causes of poor growth because it is often highly treatable when diagnosed early.

Signs and Symptoms of Growth Hormone Deficiency

Growth Hormone Deficiency is often difficult for parents to recognize because affected children usually appear healthy.

The most common sign is slow growth over time. These are the signs your child may need growht hormone testing.

Common Symptoms Include:

  • Growing less than 2 inches per year after age 5
  • Falling percentiles on growth charts
  • Being significantly shorter than classmates
  • Delayed bone age
  • Delayed puberty
  • Younger appearing facial features
  • Increased abdominal body fat
  • Delayed tooth eruption
  • Reduced muscle mass
  • Lower energy levels

Many children with Growth Hormone Deficiency are not the shortest child in class initially. Instead, parents often notice that their child is gradually falling behind peers year after year.

What Causes Growth Hormone Deficiency?

Growth Hormone Deficiency can result from several different factors.

Congenital Causes

Some children are born with abnormalities affecting the pituitary gland or hypothalamus.

Examples include:

  • Pituitary gland malformations
  • Midline brain abnormalities
  • Genetic mutations affecting growth hormone production

Acquired Causes

Growth Hormone Deficiency may also develop later due to:

  • Head injuries
  • Brain tumors
  • Radiation therapy
  • Pituitary disorders
  • Inflammatory conditions affecting the pituitary gland

In many children, no specific cause is ever identified.

Growth Hormone Deficiency vs Constitutional Growth Delay

One of the most common questions parents ask is whether their child is simply a late bloomer.

Children with Constitutional Growth Delay often have:

  • Delayed bone age
  • Delayed puberty
  • Family history of late growth
  • Normal hormone production

Children with Growth Hormone Deficiency often have:

Distinguishing between these conditions is one of the primary goals of a pediatric growth evaluation.

What Is IGF-1 and Why Does It Matter?

Insulin-Like Growth Factor 1 (IGF-1) is one of the most important markers used to assess growth hormone activity.

Growth hormone stimulates the liver to produce IGF-1, which then helps drive bone growth and development.

Children with Growth Hormone Deficiency frequently have:

  • Low IGF-1 levels
  • Delayed growth
  • Delayed skeletal maturation

While IGF-1 alone cannot diagnose Growth Hormone Deficiency, it is often an important clue.

How Growth Hormone Deficiency Is Diagnosed

A comprehensive evaluation is necessary because many growth conditions can appear similar.

Growth Chart Analysis

One of the first steps is reviewing a child's growth history.

Doctors evaluate:

  • Current height percentile
  • Growth velocity
  • Family height patterns
  • Changes in growth trajectory

These may help a parent understand how tall my child will be.

Bone Age X-Ray

A bone age X-ray evaluates skeletal maturity and remaining growth potential.

Children with Growth Hormone Deficiency frequently have a delayed bone age compared to their chronological age.

Laboratory Testing

Common laboratory tests include:

  • IGF-1
  • IGFBP-3
  • Thyroid hormones
  • Complete blood count
  • Metabolic markers
  • Nutritional markers

Growth Hormone Stimulation Testing

Because growth hormone is released in pulses throughout the day, random blood testing is not reliable.

A stimulation test evaluates how well the pituitary gland responds when stimulated to release growth hormone.

Pituitary MRI

In some cases, MRI imaging may be recommended to evaluate the pituitary gland and surrounding structures.

Delayed Bone Age and Growth Hormone Deficiency

Many children diagnosed with Growth Hormone Deficiency have a delayed bone age.

A delayed bone age means:

  • Skeletal development is occurring more slowly
  • Growth plates remain open longer
  • Additional growth potential may still exist

This finding often helps guide treatment decisions and height predictions.

Treatment for Growth Hormone Deficiency

Treatment depends on the underlying cause and severity of deficiency.

Growth Hormone Therapy

Children diagnosed with Growth Hormone Deficiency are commonly treated with recombinant human growth hormone under the supervision of a qualified physician.

Treatment typically involves:

  • Regular injections
  • Ongoing laboratory monitoring
  • Growth tracking
  • Periodic adjustment of treatment plans

The goal is not to make a child unusually tall.

The goal is to help the child reach their natural genetic height potential.

Supporting Factors for Healthy Growth

Additional factors that influence growth include:

  • Adequate sleep
  • Proper nutrition
  • Protein intake
  • Zinc status
  • Vitamin D levels
  • Regular physical activity

Growth hormone works best when the body has the resources necessary for healthy development.

What Happens if Growth Hormone Deficiency Is Not Treated?

Without treatment, children with significant Growth Hormone Deficiency may:

  • Remain substantially shorter than expected
  • Experience delayed puberty
  • Develop reduced bone density
  • Have lower muscle mass
  • Miss important growth opportunities

Because growth plates eventually close after puberty, delayed diagnosis can reduce treatment effectiveness.

Early evaluation creates the greatest opportunity for positive outcomes.

Frequently Asked Questions

How common is Growth Hormone Deficiency?

Growth Hormone Deficiency is uncommon but remains one of the most important causes of poor growth because it is highly treatable.

Can Growth Hormone Deficiency be inherited?

Yes. Certain genetic forms of Growth Hormone Deficiency can run in families.

What age is Growth Hormone Deficiency usually diagnosed?

Many children are diagnosed between ages 4 and 12 when growth patterns become more apparent. At this time parents often ask why is my child shorter than classmates?

Can a child have normal growth hormone levels and still be short?

Yes. Conditions such as Constitutional Growth Delay, Familial Short Stature, Delayed Puberty, and nutritional deficiencies can also affect height.

Is Growth Hormone Deficiency curable?

Treatment can often normalize growth velocity and significantly improve adult height outcomes when started early.

When Should Parents Seek a Growth Evaluation?

Parents should consider evaluation if their child:

  • Grows less than 2 inches per year
  • Falls off their growth curve
  • Appears much shorter than expected
  • Has delayed puberty
  • Has delayed bone age
  • Has low IGF-1 levels
  • Is significantly shorter than siblings were at the same age

Early assessment allows families to better understand growth potential and identify treatable causes of short stature.
