Short stature is a height that is less than or equal to the third percentile for a person's age, sex, and race.
Short stature is generally broken down into 3 subgroups: Familial short stature—parents are shortConstitutional delay and development—child is small for age but growing at normal rate, will reach an adult height similar to parentsCaused by chronic disease—such as malnutrition, genetic disorders, heart problems, and growth hormone deficiency
Expected Growth (Shadow) and Short Stature

Familial and constitutional delays are due to the child's genetic make-up. If both parents are shorter than average, the child will most likely have short stature. The child may also have delayed puberty. This may cause temporary short stature, but normal height will eventually be reached.
Medical conditions that may contribute to short stature include: Malnourishment—most common cause of growth failure and is generally associated with poverty
Genetic disorders such as skeletal dysplasias,
Down syndrome, and Silver Russell syndrome
Endocrine disorders such as
or growth hormone deficiency
Congenital heart diseasesKidney diseasesLiver failureSickle cell anemiaIntrauterine growth retardation or small for gestational age
Disorders of the stomach or intestines such as
inflammatory bowel disease
Lung conditions such as severe
chronic obstructive pulmonary disease
Malabsorption due to
or celiac diseaseUse of selective serotonin reuptake inhibitor (SSRI) medications—may be used to treat attention deficit disorder or obsessive compulsive disorderRadiation therapy for cancer Chronic use of steroids
Factors that may increase your child's chance of short stature include: Having family members with short staturePoor dietCertain diseases in a pregnant woman will increase risk to the newborn child Certain drugs taken by a pregnant woman will increase risk to the newborn child
Symptoms vary. Children with familial short stature do not have any disease-related symptoms. They will often reach a height similar to that of their parents.
Children who have delayed puberty will often have a close relative with the same delay. These children will also eventually catch up to their peers in height.
Symptoms that may indicate a medical condition include: Stopped or dramatically slowed growth—below the third percentile as determined by your doctorWeight loss or gain—more than 5 pounds in a monthPoor nutritionLoss of appetite
Chronic abdominal pain and
diarrheaPersistent feverChronic headaches and/or vomitingDelayed puberty—no spotting by age 15 years for a girl or no enlargement of the testes by age 14-15 years for a boy
You will be asked about your child's symptoms and medical history. A physical exam will be done. Your child's height, weight, and body proportion will be measured. The skull and facial features will also be examined.
Your child's bodily fluids may be tested. This can be done with: Blood testsUrine tests
Images may be taken of your child's bodily structures. This can be done with x-rays.
Your child may be tested for chromosomal abnormalities. This can be done with a genetic exam.
Children with familial short stature do not require treatment. For others, treatment will focus on the cause of short stature. Treatments can vary greatly, but may include medication or nutritional changes.
Medications that may be used to treat associated conditions include:
Thyroid hormone replacement therapy—may be used in children with
Growth hormone replacement—may be used in some children such as those with growth hormone deficiency,
Prader-Willi syndrome, Turner syndrome, chronic kidney disease, or idiopathic short stature
If a medication is associated with short stature, you may be advised to stop taking the medication. Make sure to talk to your doctor before stopping any medication.
Malnutrition can contribute to short stature. It may be due to a lack of proper food or other conditions like gastrointestinal problems. In either case, a change in diet may help. Talk to your doctor or dietitian to help make effective changes to your child's diet.
Short stature cannot be prevented in children who have a familial short stature or short stature from genetic conditions. However, short stature from chronic disease can be prevented by treating the condition. In some cases, you can minimize your child’s risk of developing short stature by encouraging a nutritious diet.
Pregnant women can minimize the risk of short stature in their children by: Eating a nutritious diet during pregnancyAvoiding smokingAvoiding illegal drugs
