A high TSH level—above 4.5 mU/L—indicates an underactive thyroid, also known as hypothyroidism. This means your body is not producing enough thyroid hormone. A high TSH means different things depending on whether a person has known thyroid disease. In People Without Known Thyroid Disease A hi...
What is the optimal TSH level for patients with hypothyroidism on levothyroxine replacement therapy?References 1. Weaver CM, Alexander DD, Boushey CJ, et al.

The TSH blood test is often ordered by a physician when signs of eitherhypothyroidismor hyperthyroidism are present. It can also help pinpoint the specific cause of hypothyroidism. The thyroid blood test is also ordered periodically for patients who are on medication for either thyroid condition, t...
Hypothyroidismis a disorder in which the thyroid gland does not produce enough thyroid hormones. These include thyroid-stimulating hormone, or TSH, which stimulates the thyroid gland to release two other hormones: triiodothyronine, or T3, and thyroxine, or T4. The thyroid function panel measures the...
Hypothyroidism and hyperthyroidism in pregnancy arediagnosed based on symptoms, physical exam, and blood tests to measure levels of thyroid-stimulating hormone (TSH) and the thyroid hormones T4 and (for hyperthyroidism) T3. The presence of thyroid peroxidase (TPO) antibodies indicates a likely autoimm...
Thyroid conditions stem from an inactive or underactivethyroid gland(known ashypothyroidism) or an overactive thyroid gland (hyperthyroidism). Your pituitary gland is also responsible in some cases of hypothyroidism due to its failure to make a hormone called thyroid stimulating hormone (TSH), which ...
TSH:measures how much T4 the thyroid is being asked to make. An abnormally high TSH test may mean you have hypothyroidism. Relying on TSH alone is not sufficient to make an accurate diagnosis and one reason why so many people with hypothyroid are misdiagnosed. ...
hyperthyroid phase (during which this growth factor is intrathyroidal produced and subsequently activated, stimulating thus thyroid follicular cell destruction, and increasing in an autocrine manner its own synthesis) and the second (associated with hypothyroidism) phase of post-partum thyroiditis [55]....
In short, TSH is linear, inverse, and leading. It indicates the thyroid gland isn’t producing enough hormone or hypothyroidism. Alternatively, a low TSH level indicates the thyroid is producing too much hormone or hyperthyroidism. Low TSH levels may also result in abnormalities. However, a stan...
In this case, I can be more direct: anything that cures hypothyroidism has a risk of causing hyperthyroidism. The symptoms for this start with “very annoying” and end at “permanent disability or death”, so if you’re going to try iodine, it absolutely needs to be under medical ...
