What is congenital hypothyroidism?

In a proven case of congenital hypothyroidism - whatever the cause is thought to be - the treatment is the same. It is safe, simple and effective, and involves replacing the missing thyroid hormone.

Thyroxine is taken in pill form daily for life. The correct dosage is determined by making regular estimations of the thyroid hormones present in the blood, to keep the thyroxine/T4 concentration within the normal range. This will be especially important in the first few years of life.

Frequent visits to the doctor will be necessary but these, as well as the blood tests, will become fewer once the baby's condition is brought under control. Generally, these are every 2 to 3 months for the first 2 to 3 years - once normal levels have been established.

Will there be any future precautions to be aware of?

• The most important fact to be aware of is that, with treatment, a child with congenital hypothyroidism is entirely normal
  
• There are no restrictions on normal immunisations, exercises or activities, etc
  
• As long as the thyroxine dosage is appropriate, no physical, developmental or behavioural problems will ensue as a direct result of the congenital thyroid abnormality
  
• It is also encouraging to remember that the child is not actually receiving medication, but only a replacement chemical
