The drugs are designed to normalize the thyroid hormone levels in the blood (i.e., to increase levels if they are high or decrease levels if they are low) and to control symptoms that are present.
Treatment with thyroid hormone is usually started empirically and much effort has been put into estimating the accurate initial dosage.
However, the risks of low or high thyroid hormone levels become much more apparent during pregnancy.

According to the new study, researchers found that even more modest increases in thyroid hormone were associated with an increased A-Fib risk.
have classified the patterns of abnormalities of thyroid hormone levels in ESS into four major types namely low T3 syndrome, low T3 and low T4 syndrome, high T4 syndrome, other variants.3 Low T3 Syndrome is defined as a condition in which T3 is decreased but T4 and TSH levels remain normal due to the impaired conversion of the inactive pro-hormone T4 to the biologically active hormone T3 by 5 monodeiodinase in the liver.4 It is the most common abnormality amongst NTIs observed.
