Thyroid Stimulating Hormone (TSH) is produced by the pituitary gland to regulate thyroid function. It signals the thyroid to produce thyroid hormones, which are crucial for metabolism, energy, and growth.

Individuals with symptoms of thyroid dysfunction, family history of thyroid disease, or those undergoing treatment for thyroid disorders should test their TSH levels. It’s also recommended for people experiencing unexplained weight changes, fatigue, or mood fluctuations.
Underactive Thyroid (Hypothyroidism):
Overactive Thyroid (Hyperthyroidism):
Measuring only TSH can miss subtler forms of thyroid dysfunction. TSH levels can be normal while thyroid hormones (T3 and T4) are not, which is why testing T3 and T4 alongside TSH provides a more comprehensive view of thyroid health.
