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 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:
Factors that may increase your child's chance of short stature include:
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:
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:
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:
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.
