Health condition
Short stature assessment
A child who is well below the height expected for the family, or whose growth is slowing across centile lines, deserves a proper growth assessment - most turn out to be healthy variants, but the treatable causes are worth finding early.

Key facts
The essentials at a glance.
The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.
-
Concerning patterns: height below the 0.4th centile, height far below the mid-parental expectation, or a curve crossing down through centiles
-
Common benign explanations: familial short stature and constitutional delay of growth and puberty
-
Medical causes include growth hormone deficiency, hypothyroidism, coeliac disease, Turner syndrome in girls, and chronic illness

Specialist: a consultant paediatric endocrinologist; accurate serial measurements over 6-12 months are the single most useful test
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
Height worries bring many families to clinic, and the first task is deciding whether a child is short but growing normally - tracking steadily along a low centile that fits with shorter parents - or genuinely failing to grow at a normal rate, which is a different matter entirely. Growth is a sensitive barometer of childhood health: thyroid problems, coeliac disease, inflammatory conditions and hormone deficiencies all slow growth, sometimes before causing any other symptom.
Diagnosis and treatment routes
Assessment combines precise measurement (including parents' heights to calculate the genetic target), a review of the whole growth record, a bone-age X-ray and screening bloods covering thyroid, coeliac and general health, with karyotype testing in girls to exclude Turner syndrome and growth hormone testing where the pattern suggests deficiency. Treatment follows the cause - thyroxine, a gluten-free diet, or daily growth hormone injections for confirmed deficiency - and works best started early, while plenty of growing years remain. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant paediatric endocrinologist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
A quiet reminder

Your GP knows your history and can tell you which parts apply to you. If in doubt, see them - and seek urgent care for any of the emergency symptoms described above.
Frequently asked
Common questions about Short stature assessment.
Quick, plain-English answers to what people ask us most.
-
When does short stature in a child need assessment?
A child who is well below the height expected for the family, or whose growth is slowing across centile lines on a growth chart, deserves a proper growth assessment rather than simply being reassured.
-
What causes short stature in children?
Causes range from normal familial short stature and constitutional delay of growth, to hormonal causes such as growth hormone deficiency, chronic illness, and genetic conditions.
-
How is short stature investigated?
Investigation includes careful growth chart review over time, assessment of pubertal development, blood tests including hormone levels, and sometimes a bone age X-ray and genetic testing depending on findings.
-
Is short stature always a sign of a medical problem?
No, many children with short stature simply have short parents or a normal constitutional pattern of growth and puberty, but crossing growth centile lines downward is a specific signal that warrants proper assessment.
-
How is short stature treated?
Treatment depends entirely on the cause found - growth hormone therapy for confirmed growth hormone deficiency or certain other conditions, treatment of any underlying chronic illness, or simply reassurance and monitoring for normal variants.
-
When should I see a specialist about my child's height?
See your GP if your child's growth is crossing centile lines downward or is significantly below expected family height. A private paediatric endocrinologist can typically be seen within about two weeks for assessment.
