Thyroid function and serotonin activity are highly linked. Serotonin stimulates hypothalamic TRH (Thyroid Releasing Hormone) production, leading to an increase in TSH (Thyroid Stimulating Hormone) production from the pituitary. Serotonin stimulates hypothalamic TRH production which leads to an increase in TSH production from the pituitary. Adequate ...

The main risk is to children and pregnant women associating with the person receiving I-131 treatment. Since I-131 is excreted in bodily fluids and taken up into the thyroid, those susceptible populations are at increased risk for thyroid cancer if they ingest contaminated bodily fluids. The person receiving the treatment is not because the cells that ...

The condition that you're asking about is called in the professional terminology: "madarosis" (but see the picture that I attached). As many proffessional books states, it's common in hypothyroidism, and they don't say it about hyperthyroidism. Then it make sense that it's not common in hyperthyroidism. But in medicine always can be exceptions. Regarding ...

The personal set-point of thyroid homeostasis may differ between individuals [1, 2]. Multiple studies showed that the intra-individual variation of both TSH and peripheral thyroid hormones is smaller than the inter-individual variation [3, 4]. Therefore, for individuals the range of optimality is smaller than the width of the corresponding reference range (...

This constellation may result from at least five reasons: Hypothesis #0: Both conditions (thyroid nodules and symptoms of hyperthyroidism) are independent. Hyperthyroid symptoms including anxiety, hair loss, fatigue and palpitations are unspecific. Although they are typical for thyrotoxicosis, they may also result from other conditions, e.g. masked ...

Normal. A result of 9 where the reference range is 0 - 34 indicates that you're within the normal range. For this test, an abnormal result would be a value over 34 because it's not possible to have a result below zero. Keep in mind that each testing lab can different reference ranges, and they can differ over time too.

The hypothesis is that the free hormone is the fraction which is available for uptake into the cells and interaction with nuclear receptors. The bound hormone represents actually a circulating storage that is not immediately available for such an uptake. Since some drugs and illnesses can alter concentrations of binding proteins or the binding capacity, the ...

This study from Australia https://www.mja.com.au/journal/2010/193/7/iodine-toxicity-soy-milk-and-seaweed-ingestion-associated-serious-thyroid indicates that iodine toxicity has been documented in people consuming soy milk made with kombu and illustrates the dangers of importing a foreign diet or manufactured food substance. We report a series of cases of ...
