TSH level (Thyroid Stimulating Hormone) is the first thing you check when you suspect a thyroid disorder. It acts as a signal from the pituitary to the thyroid bladder infection symptoms gland that tells the thyroid how very faster / slower it to produce thyroid bladder infection symptoms hormones T3 and T4. In primary TSH Hypothyroidism is an abnormally high level when the brain screams at the thyroid to produce more. Unfortunately, not thyroid capacity to do this without sending it out as much T3 and T4 (thyroid hormone), it can only give out - which is far too little.
TSH level is one reason often lower in summer and higher in winter. May have to do with vitamin D levels (more on that coming soon). bladder infection symptoms Typically, TSH levels longer during the day and higher at night. The higher the TSH the slower bladder infection symptoms metabolic rate and the lower the TSH - the higher bladder infection symptoms metabolism have.
Scientists and doctors disagree on what is considered to be within normal levels. From what I've read is the normal value of 0.3-2.5. In contrast, mean certain doctors a value should not exceed 2 - others say the third
It is important to note that TSH level may be within the normal even for those with hypothyroidism. There are different types of the disease (such as subclinical). Therefore, it is important to take all samples T3, T4, TPO, Tg and TRAK (antibodies against the thyroid gland). For me personally, I was initially a blood test for TSH level was found to be at 12. Then I had to go back to take the rest of the sample where the evidence showed that I had the autoimuna variant of Hypothyroidism. Other words this is Hashimoto diseace or primary hypothyroidism. Here's a great youtube video showing the interaction between TSH, T3 and T4
