What is TSH?
TSH, or Thyroid-Stimulating Hormone, is a biomarker released by the pituitary gland to stimulate the thyroid gland to produce thyroxine (T4) and triiodothyronine (T3), two hormones that are essential for regulating metabolism.
Why should you have TSH tested?
Testing TSH is useful for assessing thyroid function. It can assist in determining hypothyroidism (an underactive thyroid gland) or hyperthyroidism (an overactive thyroid gland). This test is especially recommended for symptoms such as fatigue, weight changes, irregular heartbeat, or problems with body temperature.
What does it indicate?
TSH levels provide insight into how well the thyroid gland is functioning. The amount of TSH can indicate whether the thyroid is producing too much or too few hormones relative to what the body requires.
What does a high TSH level mean?
A high TSH level may indicate hypothyroidism, where the thyroid gland does not produce enough thyroid hormones. This can cause symptoms such as weight gain, fatigue, dry skin, and sensitivity to cold.
What does a low TSH level mean?
A low TSH level may indicate hyperthyroidism, where the thyroid gland produces too many thyroid hormones. Symptoms may include weight loss, heart palpitations, increased anxiety, and heat intolerance.
