Low thyroid: Although most thyroid disease is caused by an autoimmune disorder, some people's thyroid may just not be functioning well. You need to get this test repeated plus getting thyroid hormone level at the same time to make sure this was not a lab error. It may be a good idea to consult an endocrinologist as well. ...Read more

What is considered a high TSH level?

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

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

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

High TSH: Hypothyroidism involves symptoms (fatigue, constipation, etc) and high tsh, low ft4. It is common to see people who basically feel well, have a normal ft4, but elevated tsh. 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

I have a high TSH but normal T4 levels, what does this mean?

I have a high TSH but normal T4 levels, what does this mean?

Hypothyroidism: The TSH test is10 times more sensitive for the diagnosis of hypothyroidism that the t4. The TSH is reported on a log scale so that small changes in the TSH value are caused by relatively big changes in the blood level. This is a reflection of the pituitary being extremely sensitive to change in the T3 (liothyronine) level if you have symptoms it would be wise to seek treatment. ...Read more

High tsh 8.01 all other thyroid levels normal. Worried had small nodules on thyroid last year with normal thyroid levels.

High tsh 8.01 all other thyroid levels normal. Worried  had small nodules on thyroid last year with normal thyroid levels.

Subclinical hypothyroidism.: An isolated elevation of the TSH in the face of other thyroid hormone levels being normal suggests a diagnosis of subclinical hypothyroidism. The most likely underlying cause is Hashimoto's thyroiditis and your blood should be checked for the presence of anti-thyroid antibodies. At a TSH level of eight or higher I would recommend treatment with thyroid hormone therapy. ...Read more
