TSH Gotcha We have before us multiple scenarios, which start and end in the same place. (This will be a little long, so take a cup of coffee to see you until the end.)
The adventure begins when you drag into the doctor's office complaining of weight gain, extreme fatigue, hair loss, mood swings, feeling a bit lower, and so the standard story hypothyroidism. Mr Sherlock, if you're lucky, will take these clues and decide to test for a thyroid problem.
And if you give a little blood for some tests, and our recovery scenarios.
The Big Kahuna of blood tests for thyroid TSH is illegitimate (thyroid stimulating hormone) test, our topic here.
Here's the theory behind the test: The pituitary gland, which controls the thyroid and all other parts of the endocrine system, creates TSH to say when the thyroid gland to make thyroid hormone.
aec If the pituitary determines that you have enough thyroid hormone in your system, it closes to order more. The results of TSH land within the limits of normal.
aec If you produce too much thyroid hormone, pituitary TSH back out everything and start a factor that explains the thyroid to make him fall. TSH is low.
aec If you do not have enough thyroid hormones racing through the cells, the pituitary gland found more and more TSH for thyroid to do its duty. TSH results appear anywhere between the normal and high stratosphere.
Based on this theory, a look at the results HRT decides your fate in the thyroid.
aec If the TSH is within "normal limits", it seems that you're fine. The problem is that no one agrees on what the range of "normal" is. Chances are you're not at one extreme or the other, although the TSH test is not reliable, so who knows, but that does not mean you're home free. You do not need to be away from the mark in difficulty. For example, even mild hypothyroidism explodes your chances of heart disease, but you can still be in the range of "normal".
Besides, you feel bad. Thus, the doctor offers you a caring antidepressant. And you probably feel miserable enough to take it. It will not just good, but the deal is sealed. You'll have to change doctors and try again to get proper treatment. It is not uncommon to go to six or seven or more physicians, before someone gets this right.
aec If your TSH is low, the doctor says hyperthyroidism. Maybe not, Sherlock. If the pituitary is broken, it will not produce TSH, whatever the circumstances. Most concussions damage the pituitary, and it may never recover enough to tell the thyroid to do something wonderful. So the thyroid does nothing, and the TSH test said Nobody's Home. This creates a problem because med schools teach doctors a low TSH can serve as hyperthyroidism.
They reject the gap between the hyper complaints lose weight, heart palpitations, extreme nervousness, etc. and the patient nearly catatonic in front of them. A simple pressure on the ankle to test the reflexes of the separation of the hyper hypo, but doctors do not either.
Given the combination of a so-called impossible low TSH and hypothyroid symptoms, the puzzled doctor scribbled a prescription for an antidepressant. As if! It will not make a bit of good recovery. It's like putting a plaster on his leg because you have a cold.
But what if the test is legitimately low TSH? Well, you could have an infection. And as I mentioned, the test is not reliable. Or you can really be hyperthyroidism. In all cases, please carefully before embarking on irreversible treatments hyperthyroidism. Search the tar options of alternative medicine. Let there be a last resort irreversible.
Meanwhile, and I can not believe these words come out of my fingers, you might think.
