Idiopathic Short Stature

Overview

Children with idiopathic short stature are healthy and have normal hormone levels but are much shorter than other children of the same age and sex.

Signs

• Height well below that of other children of the same age
• Normal growth rate in many cases
• Normal body proportions
• No other symptoms of illness

Causes and risk factors

By definition, no specific cause is found. Family height patterns and genetics play a role.

Diagnosis

Diagnosis is made after measuring growth over time and doing tests to rule out other causes, such as hormone, genetic, bone or chronic conditions. A bone age X-ray is usually done.

Treatment

Many children need only monitoring and reassurance. Growth hormone treatment may be considered in selected children after specialist assessment.

When to see a doctor

See a doctor if your child is much shorter than other children or seems to be growing slowly.
