TSH - THYROID STIMULATING HORMONE

Thyroid-stimulating hormone (TSH) is a hormone produced by the pituitary gland that plays a critical role in regulating the thyroid gland's function. TSH stimulates the thyroid to produce and release thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), which are essential for regulating metabolism, energy levels, and overall growth and development. The levels of TSH in the blood are a key indicator of thyroid health.

When TSH levels are elevated, it typically indicates hypothyroidism, a condition where the thyroid is underactive and not producing enough thyroid hormones. Conversely, low TSH levels suggest hyperthyroidism, where the thyroid is overactive and producing excess hormones.

Measuring TSH is crucial for diagnosing thyroid disorders and for monitoring the effectiveness of treatments for conditions like hypothyroidism and hyperthyroidism. Regular TSH testing helps ensure that thyroid hormone levels remain balanced, supporting optimal metabolic function and overall health.
