Children’s Thyroid Service
Thyroid problems in children are uncommon but important, because thyroid hormone is essential for growth and brain development. This service provides assessment and management for children and adolescents with suspected or confirmed thyroid disease.
Care is tailored to the child’s age and stage of development, with close attention to growth.
Last medically reviewed: 15 November 2025
Conditions seen
Common reasons for referral include congenital hypothyroidism detected on newborn screening, an under- or overactive thyroid in childhood, a family history of thyroid or autoimmune disease, and thyroid lumps or enlarged glands.
Some children are referred because of growth, pubertal or school-performance concerns that may relate to the thyroid.
Assessment in children
Assessment combines a careful history, examination, growth charting and thyroid blood tests, with imaging where needed. Results are interpreted against age-specific ranges, which differ from adult values.
Treatment, when needed, is monitored closely to support normal growth and development.
Working with families
Families are given clear explanations and written guidance, and management is coordinated with paediatric and school services where appropriate. Transition to adult care is planned as the child grows up.
Frequently asked questions

Are thyroid tests different for children?
The tests are similar but results are interpreted against age-specific reference ranges, which differ from adult values.
Does treatment affect growth?
Correctly treated thyroid disease supports normal growth and development. Monitoring ensures the dose stays right as the child grows.
