We have case , femal patien , age 60 years, the TSH less than 0.05 while T4 in normal range , and she has not any symptom of thyroidism , is it ok ?

Subclinical hyperthy: A low TSH with a normal T4 and no symptoms is usually subclinical hyperthyroidism. She may have a multinodular goiter that is autonomously functioning, or very early graves disease. A T3 (liothyronine) level and free T4 level should be checked. There is a higher risk of developing atrial fibrillation despite the normal T4 level, but many endocrinologists would just follow her levels for progression. ...Read more

Could an elevation in one's TSH level be indicative of hyper/hypo thyroidism?

Could an elevation in one's TSH level be indicative of hyper/hypo thyroidism?

Hypothyroidism: When the thyroid makes too little hormone (t4 and t3), the pituitary makes more TSH to try to compensate. So an elevated TSH is indicative of a thyroid that has failed or is failing, and you may need to take levothyroxine. See your doctor. ...Read more

I'm not sure what: ..units are being used to measure your TSH level, but 100??? In the USA, the standard value that labs use to measure TSH is microunits/ml and normal values range from 0.4 to 4.0 microunits/ml. If you're TSH is 100 mcu/ml, then definitely something's wrong with your thyroid or the hormones regulating it. This test result requires follow up and either clarification or treatment. ...Read more

Tsh thyroid is at 4.95, is that okay?

Tsh thyroid is at 4.95, is that okay?

Mildly high: A TSH of 4.95 is slightly high, suggesting that your thyroid level is somewhat low. It is important to test the free T4 level to see how low. Do you have symptoms consistent with an underactive thyroid? Most people with a TSH level that mildly high will have no symptoms. In that case, observation with repeat level in a few months would be reasonable. ...Read more

Hypothyroidism.: We can't necessarily predict what a thyroid gland will do over time. Are you having any symptoms consistent with either hypothyroidism (slow) or hyperthyroidism (fast)? Best to just have the blood levels checked again if you're having relevant symptoms. ...Read more

What is the cure for someone with high TSH thyroid level?

The thyroid gland may be in the early stages of failing often from underlying hashimotos thyroiditis. You and your doctor need to decide whether to just watch/follow this, or begin treatment with levothyroxine. ...Read more

The range of TSH is affected by physiological factors such as sleep , circadian variation, food intake and sleep but within the narrow range you quote there is also variations due to measurement called interassay variation. ...Read more

Been taking synthroid (thyroxine) (125) for 6+ months and just discontinued. How long until TSH/thyroid hormones return to baseline levels?

Been taking synthroid (thyroxine) (125) for 6+ months and just discontinued. How long until TSH/thyroid hormones return to baseline levels?

You need synthroid (thyroxine): If you have been diagnosed with hypothyroidism and a physician has placed you on synthroid, (thyroxine) this is a lifelong replacement therapy. If the diagnosis was correct, your thyroid can no longer produce enough thyroid hormone and without the continuous thyroid replacement therapy (synthroid) you will eventually experience all the signs and symptoms of hypothyroidism. Talk to your Dr. before stopping med ...Read more
