Nodules: Growth of thyroid nodules may represent malignancy. The only way to really know is to perform fna biopsy. Many patients with solid thyroid nodules will have normal tsh. Thyroid scans are generally no longer thought to be useful in distinguishing between benign and malignant nodules. Rai thyroid scans should be ordered in patients with suspected hyperthyroidism, not routinely for all patients. ...Read more

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

Luckily, about 95% of nodules are benign. ...Read more

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

By the way, why are you taking generic T4 an Armour Thyroid together? There is no way to monitor the dosage properly as the lab tests will be unreliable. Brand name T4 is better, safer and more reliable. ...Read more
