Graves also causes antibodies to stimulate the thyroid causing hyperthyroidism. It is not the high thyroid hormone levels that cause eye prominence.

How is tyrosine related to thyroid hormone?

How is tyrosine related to thyroid hormone?

Thyroid synthesis: Thyroglobulin is a protein in the thyroid. It contains many copies of the amino acid tyrosine. Iodine gets added to the tyrosine, and then this tyrosine gets liberated from the thyroglobulin, released into blood, and this iodinated tyrosine is thyroid hormone. But don't think you can cure hypothyroid by eating tyrosine because the body synthesizes tyrosine quite well.

Can you tell me how the body maintain thyroid hormone levels?

H-P-T axis: Hi. It's an interplay in the hypothalamic-pituitary-thyroid (H-P-T) axis. The hypothalamus secretes thyrotropin-releasing factor (TRF), which stimulates the pituitary to release thyroid-stimulating hormone (TSH), which stimulates the thyroid gland to take up iodine, organify, make, and release thyroid hormones (mostly T4, but a little T3 (liothyronine) too). The thyroid hormones feed back to suppress TRF & TSH.

Either way: There is a very common condition called "post partum thyroiditis". It can cause fluctuations in your thyroid function leading to both high and low hormone levels. Sometimes it requires medication, but sometimes it levels out on its own. You may need to consult with an endocrinologist.
