What is thyroid-stimulating hormone (TSH)?

TSH or thyroid-stimulating hormone is secreted by the pituitary gland. TSH is tested when examining thyroid function. Thyroid-stimulating hormone is essential for the production of the thyroid hormone, thyroxine.

The thyroid affects the functioning of the whole body. It regulates metabolism, affects our energy levels and mood, and much more.

When is TSH measured?

TSH level in the blood is examined to diagnose hyperthyroidism and hypothyroidism, as well as to evaluate the effectiveness of thyroid hormone replacement therapy. TSH can also be measured when the thyroid’s health needs to be investigated.

Fatigue, weight gain, and other symptoms associated with thyroid overactivity or underactivity are good reasons to measure TSH levels.

Blood tests are conducted regularly during thyroxine treatment to ensure its effectiveness. For investigating thyroid disorders, TSH measurement is primary but not the only test.

If TSH level is outside the reference values, determining free T4 hormone levels is necessary. Thyroid-stimulating hormone is highly sensitive to changes in thyroxine hormone levels.
