The name of the test is "TSH, High Sensitivity". It does not mean that you have "TSH sensitivity"; there is no such condition as "TSH sensitivity". Please post the result of your TSH test and the results of your FREE T3 and FREE T4. Include reference ranges as they vary lab to lab.
I'm well aware what TSH is, where it comes from and what it does. What do you by TSH "sensitivity"? You either have too much, not enough or just right...
TSH is counter intuitive.
Too little TSH indicates you have hyperthyroidism or over active thyroid, producing too much thyroid hormone - common symptoms are weight loss, diarrhea, hand tremors, fatigue, depression, rapid heart rate, palpitations, anxiety, hair loss.
Too much TSH indicates you have hypothyroidism or under active thyroid, producing too little thyroid hormone - common symptoms are weight gain, constipation, fatigue, depression, anxiety, muscle aches/pains, hair loss and can include rapid heart rate, palpitations,.
The right amount of TSH usually causes no symptoms, but can be deceiving because normal TSH can be present with either/both too much/too little thyroid hormones and any or all of the symptoms of either.
TSH is a screening test, at best and should never be used as the sole diagnostic test. It should always be accompanied by Free T3 and Free T4 which are the actual thyroid hormones.
TSH -The amount of Thyroid Simulating Hormone in the blood.A TSH test measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland. It tells the thyroid gland to make and release thyroid hormones into the blood.
