My child is shorter than their classmates. Is something wrong?

Not necessarily. "Short stature" is a descriptive term, not a disease. It means a child's height is well below the average for their age and gender (usually below the 3rd percentile). While some children have medical conditions affecting growth, many are simply "late bloomers" or naturally short due to genetics.

What are the most common causes?

• Familial Short Stature: If both parents are short, the child is likely to be short. Their growth rate is normal, and they are healthy.
• Constitutional Delay ("Late Bloomers"): These children are short now but will have a late growth spurt and usually catch up to their peers in late adolescence. They often have a "bone age" that is younger than their actual age.
• Systemic Illness: Untreated celiac disease, inflammatory bowel disease, or kidney problems can slow growth.
• Hormonal Issues: Hypothyroidism or Growth Hormone Deficiency (rare).

What tests will the doctor do?

• Growth Chart Review: The most important tool is seeing how the child has grown over time. A child falling off their curve is more concerning than a child steadily growing on a lower curve.
• Bone Age X-ray: A simple X-ray of the left hand and wrist to see if the bones are maturing at the same rate as the child's age.
• Blood Tests: To screen for thyroid issues, celiac disease, and growth factors (IGF-1).

Does my child need Growth Hormone (GH)?

GH is only effective and approved for specific conditions (like GH deficiency, Turner Syndrome, or chronic kidney disease) or severe Idiopathic Short Stature. It is a daily injection given for years. It is not a cosmetic treatment for a slightly short, healthy child.

What should I watch for?

If your child stops growing or grows less than 2 inches (5 cm) per year after age 3, consult your pediatrician.
