Bulimia And High Tsh
Same as others: The 3d generation TSH assays are best at the lowest ranges - the upper range is debatable as tsh, unlike most products in the blood is not distributed in populations in a bell curve. The upper limits of the "normal" range of 4 to 5 in assays of all generations is probably wrong. ...Read more
Not much: Any lab can have a temporary problems doing any test accurately. That is why an abnormal level should always be repeated to verify it. There are temporary causes for high TSH (resolving subacute thyroiditis), so that a 2nd TSH level done a few weeks after an abnormal one, could be normal. Subclinical hypothyroidism will have a high TSH with other thyroid levels normal, no symptoms. ...Read more
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 does it mean to have a high tsh reading of 16.8 and a high ft4 of 8.2 What condition does this indicate?
Hypothyroidism: The actual thyroid hormone is T4 and t3. When they are low, TSH elevates, but how high is somewhat variable, and "high tsh" per se is not dangerous. A low t4/t3 can be dangerous; TSH is a good marker of thyroid function, but often it is necessary to measure ft4 or t3. 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 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
Stimulates Thyroid: As the name implies, TSH = thyroid stimulating hormone so this hormone does stimulate thyrocytes. If you have hypothyroidism (lazy thyroid), the high TSH will keep stimulating the thyroid gland to make more hormones and that is why we treat with thyroid hormone (or in iodine deficient areas iodine therapy may help). ...Read moreSee 1 more doctor answer
