AND ITS REASONS
, Overview of Thyroid
Function
• The thyroid gland, located in the neck, plays a
pivotal role in regulating metabolism and energy
expenditure through the secretion of thyroid
hormones.
• Thyroid hormones are synthesized from the
amino acid tyrosine and iodine, emphasizing
the importance of dietary iodine in maintaining
thyroid function.
• The hypothalamus and pituitary gland regulate
thyroid hormone production through a feedback
mechanism involving thyroid-stimulating
hormone (TSH), which stimulates the thyroid
to produce T3 and T4.
