This study found that when the thyroid is working less efficiently (higher TSH relative to free T4), the thyroid nodules tend to be more solid on ultrasound, suggesting hormone imbalance may affect nodule texture.

In people with thyroid diseases, higher levels of TSH in the blood are linked to lower amounts of iodine, selenium, and zinc in the thyroid tissue, indicating that thyroid function may be related to the balance of these trace elements.

In people with thyrotoxicosis caused by taking too much thyroid hormone medication, the brain's control system for thyroid hormone levels behaves differently than in people whose thyroid gland overproduces hormones on its own. Specifically, TSH stays low even when thyroid hormone levels are higher than normal.

Kids can have an overactive thyroid even if their TSH blood test looks normal, especially if they have a small overactive lump in the thyroid that makes hormones on its own.
