Some endocrinologists recommend that people whose hypothyroidism symptoms persist despite normal TSH levels try adding synthetic triiodothyronine (T3) to their levothyroxine therapy.

Why do doctors not test T3?

Doctors don't usually order the T3 test if they suspect hypothyroidism, or an underactive thyroid. Other tests can better spot this thyroid issue. The T3 test can also help your doctor identify thyroid cancer and other uncommon conditions that can affect your thyroid.

Can too much T3 cause weight gain?

According to Dr. Kitahara, if someone has low thyroid function, their TSH is high, and the thyroid hormones known as T3 and T4 are low—and weight gain often occurs. If someone has an overactive thyroid or hyperthyroidism, TSH is usually low, the T3 and T4 are high, and weight loss occurs.

Does Synthroid affect T3 or T4?

T3 is more potent that T4, which means that one mg of T3 has a greater effect on the body than one mg of T4. Levothyroxine (Synthroid) is a synthetic version of T4, and liothyronine (Cytomel) is a synthetic version of T3.
