Signs and Symptoms of Low Thyroid in Children

Hypothyroidism is a medical condition that occurs when the thyroid gland does not produce enough thyroid hormone. This condition is the most common disorder affecting the thyroid. Many of the signs and symptoms of hypothyroidism in children differ depending on their age. Being able to recognize them is important in getting a timely and accurate diagnosis.

Newborn Symptoms

• When newborns develop hypothyroidism, it is referred to as neonatal hypothyroidism. Symptoms include a hoarse cry, a protruding navel (umbilical hernia), slow bone growth, poor appetite, constipation and jaundice (yellowing of the skin or eyes).

Childhood Symptoms

• Children who develop hypothyroidism between infancy and adolescence are considered to have juvenile hypothyroidism. Symptoms include delayed tooth development and slow growth, according to the Children's Hospital Boston. Delayed growth can sometimes cause the child's limbs to be abnormally short.

Adolescent Symptoms

• Adolescent hypothyroidism is characterized by delayed growth, weight gain, delayed puberty, slow pulse, hoarse voice, dry skin, slurred speech, swollen and puffy face, droopy eyelids and hair loss.
