No. An overproduction of TSH would cause hyperthyroidism.
hypothyroidism
Some patients report weight gain with subclinical hypothyroidism. Although the T4 is normal in subclinical hypothyroidism by definition, some patients report symptoms with only the elevated TSH.
Increase in thyroid hormone will lower TSH production, because there is a feedback loop between TSH that stimulates the production of thyroid hormone and the hormone that then will then regulate the stimulation of TSH so that thyroid hormone is not over produced.
It is a test for hypothyroidism and evaluates thyroid function.
Because TSH is a part of the body's negative feedback system which controls the thyroid's output of thyroid hormones, a DECREASE of TSH would indicate hypERthyroidism. An INCREASE of TSH indicates hypOthyroidism.
A TSH of 8.7 can be indicative of several diseases/disorders depending upon other lab and imaging results and impressions. The most common condition would be hypOthyroidism. What has caused the hypothyroidism would then be the next question.
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.
The thyroid gland is involved in hypothyroidism. Not enough thyroid hormone is being produced. The pituitary gland prduces thyroid stimulating hormone (TSH) and so is related to hypothyroidism.
I had a 110 TSH and my doctor told me that my thyroid gland wasn't working at all. I was diagnosed that day with hypothyroidism and prescribed synthroid. I hope this helps and that you are under the care of a good doctor. HYpothyroidism is very treatable but can be dangerous if left untreated.
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.
Thyroxine free index. "elevated TsH and low fT4 or fTi indicates primary hypothyroidism due to disease in the thyroid gland. a low TsH and low fT4 or fTi indicates hypothyroidism due to a problem involving the pituitary gland. a low TsH with anelevated fT4 or fTi is found in individuals who have hyperthyroidism."
In addition to the test for TSH, the value of which is questioned by some, T3, T4, and Free T3 and Free T4 are often used to help diagnose hypothyroidism. A Reverse T3/Free T3 Ratio is also used by some doctors.
