What is considered a high TSH level?

Above 4.5: In most labs, a value above 4.5 is high. However, symptoms related to low thyroid correlate much better with free T4 levels, rather than tsh. There are many people with elevated tsh, normal free t4, who feel perfectly normal (subclinical hypothyroidism). Persistently high TSH levels is indicative of a failing thyroid. ...Read more

What is a dangerously high TSH level?

What is a dangerously high TSH level?

Hypothyroidism: The actual thyroid hormone is T4 and t3 (liothyronine). When they are low, TSH elevates, but how high is somewhat variable, and "high tsh" per se is not dangerous. A low t4/t3 (liothyronine) can be dangerous; TSH is a good marker of thyroid function, but often it is necessary to measure ft4 or t3 (liothyronine). A mild elevation of TSH (eg. 4-10) is often without any symptoms and a normal ft4. ...Read more

Can a high TSH level but normal T4 cause hypothyroid symptoms or not?

Can a high TSH level but normal T4 cause hypothyroid symptoms or not?

Yes: Hypothyroidism can be primary - caused by a weak thyroid gland or secondary to other hormonal problems, like a pituitary problem. Or your thyroid can become dysfunctional secondary to high insulin, estrogen or cortisol. If you have functional hypothyroidism, this problem can go undetected by routine screening tests. More extensive testing can often reveal abonormalities. This is very common. ...Read more

What can cause high TSH level after several years of Synthroid (thyroxine) for post ablative (graves) hypothroidism?

What can cause high TSH level after several years of Synthroid (thyroxine) for post ablative  (graves) hypothroidism?

Usually low Thyroid : Post ablative hypothyroidism is a condition where the thyroid gland is not functioning well and thus the patient needs more thyroid hormone. A "high tsh" actually mean there is not enough thyroid in the blood, thus an increase in dosage of the synthroid (thyroxine) is needed. Go see your family doctor and he/she will make adjustments and recheck the TSH level. This is very sensitive to thyroid in the body. ...Read more

32years old male high TSH level and normal T3 (liothyronine) and t4, 5.58 tsh//ft3, free, serum 4.92 , 3.2 ft4, fee, serum 17.5 , 1.36. Im on 75mg T4 didn't help fatigue.

Thyroid: The TSH is only minimally elevated and that may well be simply a lab error. Your t3 (liothyronine) and T4 are near the top of the reference interval. Put this together and it is unlikely that your thyroid labs are contributing to your fatigue. Are you sleeping well? Are you overweight? You might need to have a sleep study. Please check with your primary care doctor. ...Read more

My last blood results showed a high TSH levels but t3andt4 in normal range. Should i see someone regarding hypotyhroidism?

Yes: An elevated TSH indicates that your pituitary gland feels that your thyroid level is somewhat low. The fact that the T4 and T3 (liothyronine) are normal means that the problem is still mild. If you have symptoms of an underactive thyroid, treatment with thyroid hormone is indicated. If you have no symptoms, and the TSH is only mildly high, one can repeat the level in a few months and see if it has changed. ...Read more

33 yr M 6'2 185 pounds. High TSH levels but normal free T4, whst exactly does this mean?

Subclinical hypothyr: Hi. That is commonly seen, now that we screen so well for disorders of thyroid function. It's called subclinical hypothyroidism, meaning that with extra push from the pituitary (TSH), the remaining thyroid tissue is able to make thyroid hormone in the normal range. You should start taking thyroid hormone now, and not wait till your metabolic tank is empty. Good luck! ...Read more
