"Hypothyroidism-This is the state of not making enough thyroid hormone, and is the most common thyroid problem associated with DS. This can be present at birth (congenital) or may occur at any age (acquired). Every state in the US and many other countries routine screen all newborns for hypothyroidism. In newborns and infants with DS, the most common reason for hypothyroidism is that the thyroid did not form correctly in the fetus. In acquired hypothyroidism, the most common reasons in toddlers and older children with DS is (1) autoimmunity (where the body makes antibodies against its own thyroid) and (2) thyroiditis, where the thyroid tissue becomes replaced with white blood cells and fibrous tissue (Hashimoto thyroiditis)
The symptoms of low thyroid hormone are difficult to pick up, especially in infants. They include decreased growth, decreased development, an enlarged tongue, decreased muscle tone, dry skin and constipation -- all of which might be expected in an infant with DS. So, it is recommended that all infants with DS be checked at birth, 6 months of age, 1 year of age, and once a year thereafter for thyroid function, regardless of their growth."
Brooklynn's thyroid test came back normal!! And we continue pray for progress and good health.
