Recognizing Hypothyroidism Symptoms in Children and Teens

Hypothyroidism isn't limited to adults; it can also affect infants, children, and teenagers. Since young individuals have developing immune systems, it's important to identify signs early. Children's hypothyroidism can be present from birth (congenital) or develop later (acquired). Congenital hypothyroidism occurs at birth, while acquired forms appear during childhood or adolescence.

Early signs in infants
Some newborns may be born with or develop a faulty thyroid gland, causing congenital hypothyroidism. Symptoms include:

  • Enlarged, protruding tongue
  • Facial swelling
  • Difficulty swallowing during feeding
  • Yellowing of skin and eyes (jaundice)

Progressing cases may lead to excessive sleep and constipation.

Signs of hypothyroidism in infants, children and teenagers
Severe hypothyroidism in infants can impair both mental and physical growth. Early detection is crucial for effective treatment. Since signs can be subtle or absent at birth, routine screening exists in hospitals. For home births, parents should seek professional screening.
In older children and teens, hypothyroidism may show similar symptoms as adults, such as fatigue, constipation, memory issues, depression, weight gain, muscle and joint discomfort, and coarse hair. Additional signs include:
  • Delayed puberty
  • Frequent headaches
  • Vision problems
  • Delayed permanent teeth development
  • Stunted growth, possibly leading to short stature
  • Cognitive delays

If these symptoms are observed, prompt medical consultation is essential. Early diagnosis and intervention ensure healthy development, preventing long-term complications. Treatment often involves hormone replacement therapy, which, while initially causing side effects like restlessness or headaches, stabilizes health over time. Regular monitoring and lifestyle changes can support full recovery and growth.
