I'm 27 year old male with a thyroid stimulating hormone level of 3.92 miu/l and ft4 (free thyroxine) of 1.3 ng/dl. Do I have a thyroid problem?

Thyroid: I would need to know the free t3, (liothyronine) reverse T3 (liothyronine) and the tpo and tg antibodies to see if you are producing antibodies to your thyroid. The new level per the american academy of endocrinology lowered the upper normal for TSH to 3.5. ...Read more

Hypothyroid: Your question was truncated so not sure the rest, but a TSH of 4.8 indicates a possible mild hypothyroid. This should be repeated on a separate occasion and a free T4 should be measured to confirm hypothyroidism. Would then need to consider treatment. ...Read more

Where is the thyroid-stimulating hormone produced?

Where is the thyroid-stimulating hormone produced?

Pituitary Gland: Tsh (thyroid stimulating hormone) is made in the pituitary gland, which lies just below the brain. The brain and pituitary monitor circulating levels of thyroid hormone. If thyroid levels are low, the pituitary releases higher levels of TSH to get the thyroid gland to make more thyroid hormone. If thyroid levels are high, lower levels of TSH provide less stimulation to the thyroid. ...Read more

What happens when thyroid stimulating hormone goes up?

What happens when thyroid stimulating hormone goes up?

TSH increase: Thyroid stimulation hormone (TSH) is released by the pituitary gland in response to the amount of thyroid hormone sensed in the blood. If the blood level of thyroid hormone is low then the pituitary increases the amount of TSH into the blood in order to get the thyroid to release more thyroid hormone. Therefore a rising or increasing TSH may indicated a failing or under functioning thyroid. ...Read more
