Taking ptu (propylthiouracil) for overactive thyroid and Clomid also; does smoking affect thyroid hormones?

Eye disease: Smoking will greatly increase your risk for developing grave's exophthalmopathy. Essentially, the eyes are pushed out because of immune deposits behind them. This will make it difficult for you to close your eyes. People go blind from this depending on severity. We don't understand why smoking increases your risk but it does. ...Read more

What pituitary hormones cause the adrenal gland to produce mineralocorticoids, glucocorticoids, and androgens and estrogens including pregnenolone?

What pituitary hormones cause the adrenal gland to produce mineralocorticoids, glucocorticoids, and androgens and estrogens including pregnenolone?

Pituitary & steroids: Hi. Pituitary ACTH regulates adrenal cortisol production; it also acutely stimulates aldosterone, but is not the principle regulator. LH principally stimulates gonadal steroid hormone production (both genders make androgens & estrogens, but in opposite dominance). Pregnenolone is early in the steroidogenic pathway in both adrenals and gonads. Good luck! ...Read more

Why hyperthyroid can cause gynecomastia? What's the connection thyroid hormone and estrogen, testosterone?

Why hyperthyroid can cause gynecomastia? What's the connection thyroid hormone and estrogen, testosterone?

Complex interaction: Gynecomastia can occur in hyperthyroidism due to an induced increase in peripheral aromatase activity leading to an increase in circulating estrogen levels, and thus decreased testosterone levels. Most of the estrogen in men is made from the peripheral conversion of testosterone and other androgens to estrogens. Other mechanisms are probably at play as well. ...Read more

Can metformin interfere with the absorbtion of thyroxine and cytomel (liothyronine)?

Can metformin interfere with the absorbtion of thyroxine and cytomel (liothyronine)?

One report suggested it could lower TSH levels in some patients but with no effect on thyroid hormone levels (t4). I recommend you have your levels checked if symptomatic or as recommended by your provider. ...Read more

Thyrolar (thyroxine and liothyronine) and weight loss common?

We no longer: Use thyroid hormones to augment weight loss. It can have serious complications like irregular heart rhythms.

Hypothyroidism can lead to weight gain and restoring levels to normal(thyroid wise) can help some element of weight loss. in reality, it doesn't usually lead to significant weight loss. ...Read more

I have hypocretin deficient narcolepsy which reduces TSH levels along with autoimmune hypothyroidism. Is the TSH test reliable to gauge my thyroid?

I have hypocretin deficient narcolepsy which reduces TSH levels along with autoimmune hypothyroidism. Is the TSH test reliable to gauge my thyroid?

Not always: TSH is not always a reliable test, because it relies on what the pituitary thinks, but different tissues may have different sensitivity to thyroid hormone. In addition, some people make too much reverse T3 (liothyronine), (liothyronine) which can block the action of T3 (liothyronine). Google "stop the thyroid madness" ...Read more

Thyrolar (thyroxine and liothyronine) effect on weight loss?

Thyrolar (thyroxine and liothyronine) effect on weight loss?

Ideally, none: Thyroid hormone in any form is not a weight loss product. Many people, especially those with weight problems to begin with, find that taking too much thyroid hormone can lead to weight gain just as easily as taking too little thyroid hormone.
