Nonetheless, the authors quite rightly point out that based on their findings, it would be reasonable to aim for free T 4 and TSH levels within the normal range in order to minimize the risk hypothyroidism overtreatment, rather than In the upper and lower half of normal, respectively, as currently recommended 2. Abdominal bloating. Another explanation for congenital hypothyroidism is that the thyroid is in a normal location but it cannot make a normal amount of thyroid hormone. Early thyroid scanning is controversial but may help identify the cause: for example, an ectopic gland indicates permanent congenital hypothyroidism; absence of thyroid gland uptake is associated with thyroid aplasia or hypoplasia; and normal scan findings or a goiter may indicate a genetic defect in T 4 synthesis.
