What is a low thyroid?
The thyroid is a gland which produces hormones. Low thyroid would mean that your thyroid is not functioning as it should. There are a few medicines that you can take to correct the situation.
What is the medical term for condition of low level of hormone secreted by a gland in the neck?
The medical term for a low level of the hormone secreted by the thyroid gland in the neck is "hypothyroidism." This condition occurs when the thyroid gland does not produce enough thyroid hormones, leading to various metabolic issues and symptoms such as fatigue, weight gain, and sensitivity to cold. It can be diagnosed through blood tests measuring levels of thyroid-stimulating hormone (TSH) and thyroid hormones (T3 and T4).
What causes a pituitary gland not to release enough hormones?
You have the various releasing factors, that come from the hypothalamus. The low level of the hormones from the target organ like thyroid may stimulate thyroid stimulating hormone from the pituitary.
Why low TSH is called hyperthyroidism and high TSH is called hypo thyroidism?
TSH is not a thyroid hormone - it is a pituitary hormone called Thyroid Stimulating Hormone. It's job is to tell the thyroid how much thyroid hormone to produce. This is called a negative feedback system.The thyroid produces hormone.The brain reads that there is insufficient hormone in the bodyThe pituitary gland in the brain produces more TSH that turns the thyroid onMore TSH means the thyroid produces even more thyroid hormone.When there is too much thyroid hormone in the body, the pituitary turns off TSH as the body doesn't need any MORE thyroid hormone.If the brain, pituitary and thyroid are working properly, thyroid hormones T4 and T3 will be high (hypERthyroidism) when TSH is low, and thyroid hormones T4 and T3 will be low (hypOthyroidism) when TSH is high.
Why low TSH is called hyperthyroidism and high Tsh is called hypo thyoridism?
TSH is thyroid stimulating hormone. It is produced by the pituitary to turn on the thyroid gland. If TSH is low, that is because there is sufficient (or too much ) thyroid hormone in the body, so the pituitary needs less to keep the thyroid functioning. Thyroid hormones measured in lab tests are usually FreeT4 and FreeT3.
What is the meaning of tsh laboratory test?
A thyroid stimulating hormone (TSH) test is an initial test used to determine how your thyroid is functioning. A high TSH level indicates that the thyroid gland isn't making enough hormones, causing hypothyroidism. Conversely, if the TSH level is low it indicates an overactive thyroid, known as hyperthyroidism. The TSH normal level range that most physicians refer to is .3 to 4.5.
What is a condition of a deficient thyroid?
Primary hypothyroidism is caused by a problem with the thyroid gland itself that produces a low amount of thyroid hormone.Secondary hypothyroidism occurs when another problem interferes with the thyroid's ability to produce hormones. For example, the pituitary gland and hypothalamus produce hormones that trigger the release of thyroid hormone.A problem with one of these glands can make your thyroid underactive.Sometimes, an underactive thyroid that results from a problem with the hypothalamus is called tertiary hypothyroidism.

A thyroid stimulating hormone (TSH) test is an initial test used to determine how your thyroid is functioning.

Can you have thyroid storm with tsh level of 0.01?
Yes, a thyroid storm can occur even with a very low TSH level, such as 0.01, which indicates hyperthyroidism. Thyroid storm is a severe and potentially life-threatening exacerbation of hyperthyroidism, characterized by significantly elevated levels of thyroid hormones (T3 and T4) rather than just low TSH. It's important to assess clinical symptoms and other thyroid hormone levels to confirm the diagnosis, as TSH can be suppressed in hyperthyroid conditions.
What is The hormone that targets the thyroid gland and triggers the release of thyroid hormone is?
The hormone that targets the thyroid gland and triggers the release of thyroid hormone is thyroid-stimulating hormone (TSH). It is produced by the pituitary gland in response to low levels of thyroid hormones in the blood. TSH binds to receptors on the thyroid gland, stimulating it to produce and release thyroid hormones.
What does it mean if your free T4 is low?
Insufficient levels (low levels) of circulating thyroid hormones is the biochemical hallmark of an under-active thyroid, a condition referred to as hypothyroidism.
Regulation of the release of T3 and T4 from the thyroid gland is controlled by negative feedback?
When the level of the thyroxine increase, the level of the thyroid stimulating hormone decrease. So in turn the level of the thyroid hormone decreases. When the level of the thyroxine decrease, the level of the thyroid stimulating hormone increase. This in turn increase the level of the thyroxine. This explanation does not explain to how the level of the hormone is regulated at that particular level. But then this explanation satisfy most of the people.
