In hypothyroidism, the levels of thyroid hormones (T3 and T4) are low due to an underactive thyroid gland. In response to this deficiency, the pituitary gland produces more thyroid-stimulating hormone (TSH) to stimulate the thyroid to produce more hormones. Consequently, TSH levels are elevated in individuals with hypothyroidism. This combination of low thyroid hormone levels and high TSH is a key indicator of the condition.

How Hypothyroidism is also Known?
I have hypothyroidism and I'm 16 years old. Hypothyroidism is basically when your thyroid gland (located in your neck) does not produce enough hormones (TSH) essential fr your growth and metabolism. I have to take Levothyroxine in order to raise my TSH levels in my blood (which are levels of the thyroid hormone in the bloodstream.) to make it normal again.
How does taking remyline help thyroid patients?
Vitamin B12 helps in reducing the TSh levels and controllng hypothyroidism (I was prescribed high dosages of B12 as i had high TSH levels due to hypothyroid)
What level is considered hypothyroidism?
Hypothyroidism is typically diagnosed when a person's thyroid-stimulating hormone (TSH) level is above 4.0 milli-international units per liter (mIU/L). A TSH level between 4.0 and 10.0 mIU/L usually indicates mild to moderate hypothyroidism, while levels above 10.0 mIU/L suggest more severe hypothyroidism. Additionally, low levels of free thyroxine (T4) can further confirm the diagnosis.
What if your TSH level is high?
Thyroid stimulating hormone (TSH) is the signal that the brain sends to the thyroid to tell the thryoid how much hormone to make. Markedly high levels are almost always due to an underactive thyroid gland (hypothyroidism). Mildly elevated levels are often normal.
Causes of high TSH?
hypothyroidism
Does the over production of tsh cause hypothyroidism?
No. An overproduction of TSH would cause hyperthyroidism.
What does a tsh test of 2.8 mean?
It means that the level of thyroid stimulating hormone (TSH) in your blood stream is lower than it should be. Ideally it should be between 0.35 and 5 U/L. A TSH of this level can be caused by a number of different things. 1. Taking too much thyroxine or triiodothyronine to treat hypothyroidism 2. Hyperthyroidism 3. Secondary Hypothyroidism: this is where both the levels of TSH and free T4 are low
What is secondary hypothyroidism?
Secondary hypothyroidism is a condition where the thyroid gland produces insufficient hormones due to a problem with the pituitary gland, which fails to produce adequate thyroid-stimulating hormone (TSH). This can result from various factors, including tumors, trauma, or other diseases affecting the pituitary. Unlike primary hypothyroidism, where the issue originates in the thyroid itself, secondary hypothyroidism indicates that the pituitary gland's dysfunction is the root cause of low thyroid hormone levels. Diagnosis typically involves assessing TSH and thyroid hormone levels, along with imaging studies if necessary.
What is the difference between primary and secondary hypothyroidism.?
Primary hypothyroidism is caused by a deficiency in the thyroid itself. Secondary hypothyroidism is caused by an "outside" influence, usually a medication that causes the thyroid to not secrete the necessary hormones or an insufficient quantity, or may be caused by a primary disease process that in turn affects the thyroid gland. Sometimes secondary hypothyroidism is caused by the treatments for cancer, for example.
What kind of test is TSH?
It is a test for hypothyroidism and evaluates thyroid function.
As thyroxine levels increase in the blood they exert negative feedback on the release of TSH by the pituitary gland. What effect will this have on the release of TSH?
As thyroxine levels increase the amount of TSH produced will decrease. On the other hand, when TSH levels increase the thyroxine levels will decrease. This is what causes the TSH/thyroxine levels to fluctuate.
Why would a person have thyroid problems if his anterior pituitary gland was damaged?
Anterior pituitary secretes the hormone THS. That is thyroid stimulating hormone. In absence of the anterior pituitary the hormone is not secreted by the thyroid and you get the hypothyroidism.
