What is the Thyroid and What Does TSH Do?

The thyroid gland is a butterfly-shaped gland located just beneath the neck. It produces hormones that control energy levels, metabolism, and overall growth and development. It’s important to note that the thyroid produces two important hormones: thyroxine (T4) and triiodothyronine (T3). Plus, the pituitary gland produces thyroid-stimulating hormone (TSH), which is essential for controlling thyroid hormone production. TSH serves primarily as a messenger, informing the thyroid gland when to produce more or fewer thyroid hormones.

What Do Low TSH Levels Mean?

Whenever your TSH level is lower than the expected range, then you may have hyperthyroidism. This happens when the pituitary gland detects excessive thyroid hormone levels and responds by lowering TSH production. Let us know the complications related to hyperthyroidism.

  • Thyrotoxic crisis (thyroid storm).
  • Atrial fibrillation
  • Visual issues
  • Osteoporosis
  • Risk factors for Graves’ disease

What Do High TSH Levels Mean?

If someone has a high level of TSH, it means they may have hypothyroidism. Hypothyroidism may occur when the pituitary gland makes up for low thyroid hormone levels by producing more TSH. Moreover, this type of condition is often found in older women, but it can affect either gender at any age. Furthermore, if this condition in adults remains untreated, hypothyroidism may face the following risks and complications.

  • Heart disorders
  • Heart strokes
  • Peripheral neuropathy
  • Infertility
  • High blood pressure
  • Goiter
