Congenital hypothyroidismis usually tested for at birth. It is a condition resulting from an absent or under-developed thyroid gland, or one thathas developed but cannot make enough thyroid hormone, making the child hypothyroid. The term ‘congenital’ means that thecondition is present at birth. This can be hereditary and the most common cause of hypothyroidism in children is a family history of the disease. Forsome babies, their thyroid gland does not form in its normal position in the neck. In others, the gland does not developat all. And for others, it’s underdeveloped. The National Academy of Hypothyroidism estimates that 1 child in every 2000-4,000 childrenis born with hypothyroidism. That’s about 3000 a year in the UK according to the BTF.

Most children born with congenital hypothyroidism look ‘normal’ and have no obvious symptoms, which is why it is important that all children are tested at birth.

Some babies with hypothyroidism are sleepy and difficult to feed, although lots of babies have these symptoms without beinghypothyroid. Other symptoms in babies may include constipation, low muscle tone and as mentioned about older children, poorgrowth. As long as it is caught early on and medicated correctly, it shouldn’t greatly impact the child’s life.

Screening is performed at about five days old, with a heel-prick blood test. A small amount of blood is usually tested forjust TSH. But they can develop thyroid problems as they get older, so just because they may have had the all clear at birth,it’s worth bearing in mind the symptoms for their later life, too.

Medication is usually needed for life, and it is important that doses aren’t missed. The medication usually given is T4-only,such as Levothyroxine. This may prove less beneficial as the child ages and after a certain age you may consider a straightT3 or T3 and T4 combination.
