TSH dosing, the main test in the diagnosis of thyroid disorders
TSH, ie thyroid stimulation hormone, is produced by the pituitary gland. This is intended to monitor the amount of thyroid hormone released into the blood. Your doctor may recommend testing for TSH in your blood, especially when there is a suspicion of hypothyroidism or hyperthyroidism.
The pituitary gland, which is located in the brain the moment it senses certain abnormalities, releases the thyroid stimulating hormone. In other words, TSH.
Also, when we are stressed, upset, the thyroid will not produce the required amount of hormones, and the pituitary gland increases the level of TSH.
The level of TSH in the blood is paramount when a diagnosis of hypothyroidism or hyperthyroidism has to be established by the physician.
Doctors claim that the normal values of TSH are in the range 0.5 mU / I – 5.0 mU / I. Any change in this level can signal the existence of a medical problem. For example, when a patient has a high level of TSH there may be hypothyroidism. As even small values are not right. Specifically, too low TSH values suggest the existence of hyperthyroidism. But in order to establish a diagnosis of certainty, the doctor will require more tests, not just the value of the TSH. Thus, the thyroid hormones T3 and T4 will also be harvested when a diagnosis of hypothyroidism or hyperthyroidism is sought.
At the same time, when a woman is near menopause or perimenopause, it is possible that the endocrinologist or even the gynecologist may request this value of TSH.
Careful! If a woman is pregnant, the TSH values change, but it does not mean there is a problem.
Which means too low a TSH level:
- Graves disease,
- Too much iodine in the body,
Which means too high a level of TSH:
- Thyroid Hashimoto,
- TSH-secreting tumors
Regardless of the outcome of these analyzes, you should not worry. Hypothyroidism can be treated with the replacement of synthetic thyroid hormones that will be taken daily. Hyperthyroidism is treatable with radioactive iodine, anti-thyroid or surgical drugs.
