Short stature refers to any person who is significantly below the average height for a person of the same age and sex.
The term often refers to children or adolescents who are significantly below the average height of their peers.
A growth chart is used to show a child's current height and how fast he or she is growing. It can compare your child to other children of the same age and gender (male or female).
If a child's height is more than 2 SD's below the average height of other children the same age, the child is said to have short stature. This means that almost all of the other children that age (more than 95% or 19 out of 20) are taller.
Your health care provider will monitor your child's growth rate over time.
Many parents become worried if their children are shorter than most or all of the children around them. However, short stature is not necessarily a sign of a health problem.
Short stature that has no medical cause (idiopathic short stature) can be due to:
Short stature may be a symptom of a number of medical conditions or problems, including:
This list does not include every possible cause of short stature.
All children should have their growth and development monitored on a regular basis.
If your child appears to be much shorter than most children his or her age (or if the growth rate has decreased or stopped), call your health care provider.
The health care provider will perform a physical examination. The child's height, weight, and arm and leg lengths will be measured. If the short stature appears to be a sign of some medical condition, further tests, including laboratory studies and x-rays, may be needed.
To learn more about possible causes, the health care provider will ask questions, such as:
A bone age x-ray is often done. X-rays are usually made of the left wrist or hand.
Girls with short stature may have a genetic test done to check for certain diseases, such as Turner syndrome.
Other tests may include:
Although your health care provider keeps records of height and weight from routine examinations, you may find it helpful to keep your own records. You may want to bring these records to your health care provider's attention if the growth seems slow or the child seems small.
A child's short stature will often affect self-esteem. Providing emotional support is an important part of treatment. Children may be teased by classmates and friends. Family, friends, and teachers should be sure to emphasize the child's other skills and strengths.
Children of short stature who are found to have a lack of growth hormone in their body will usually be treated with growth hormone injections. See: Growth hormone deficiency
Growth hormone injections are also used to treat children with Turner syndrome, Prader-Willi syndrome, chronic kidney failure, or idiopathic short stature (ISS).
Children who are of short stature but who have normal growth hormone levels usually do not need growth hormone injections. These children may only receive growth hormone injections when:
Some boys with short stature who also have delayed puberty may receive certain medicines containing the male hormone, testosterone.
