Why is Krista’s TSH level low instead of high?

If you have Graves’ disease, your thyroid-stimulating hormone (TSH) level will probably be very low because the pituitary gland will try to compensate for the excess T3 and T4 hormones in the blood. It’ll stop producing TSH in an attempt to stop production of the thyroid hormones.

How is secretion of TSH regulated under normal conditions?

At the pituitary level, TSH is a glycoprotein secreted by the basophilic thyrotropes. TSH secretion is regulated by negative feedback of thyroid hormones, i.e. the higher the serum levels of these hormones, the lower TSH release and vice versa, and stimulation from TRH. … Cells of the thyroid gland contain TSH receptors.

What can happen if an overactive thyroid is left untreated?

If left untreated, hyperthyroidism can cause serious problems with the heart, bones, muscles, menstrual cycle, and fertility. During pregnancy, untreated hyperthyroidism can lead to health problems for the mother and baby. The thyroid is a small gland in your neck that makes thyroid hormones.

What is a TSH level for hyperthyroidism?

A high TSH level indicates that the thyroid gland is not making enough thyroid hormone (primary hypothyroidism). On the other hand, a low TSH level usually indicates that the thyroid is producing too much thyroid hormone (hyperthyroidism).

Does TSH respond to t3 or t4?

TSH, in turn, stimulates thyroid follicular cells to release thyroxine or T4 (80%), and triiodothyronine or T3 (20%). Somatostatin, on the other hand, is another hormone produced by the hypothalamus that inhibits the release of TSH from the anterior pituitary.

What inhibits TSH secretion?

The hypothalamus, in the base of the brain, produces thyrotropin-releasing hormone (TRH). TRH stimulates the anterior pituitary gland to produce TSH. Somatostatin is also produced by the hypothalamus, and has an opposite effect on the pituitary production of TSH, decreasing or inhibiting its release.
