Thyroid Function and Disorders

The video tutorial explains the concept of goiter, an enlarged thyroid gland, and its characteristics. It covers the initial approach of doctors, including blood tests like TSH, T3, and T4 to assess thyroid function. The video also discusses diagnostic procedures such as thyroid ultrasound and biopsy to evaluate nodules and potential cancer. Additionally, it explains the use of thyroid scans to determine gland functionality and the interpretation of blood tests to identify thyroid states like hypothyroidism, hyperthyroidism, and euthyroid.
