ALL YOU NEED TO LEARN ABOUT THYROID DISEASE
The thyroid gland is the largest endocrine gland in the body. It is a butterfly shaped structure that is present in the front of the neck. It secretes thyroid hormone – also called thyroxine(T4). It also secretes a small amount of triiodothyronine (T3). The thyroid gland requires iodine to synthesize thyroid hormones. The thyroid hormones regulate the metabolic rate of the body. All the tissues in the body require thyroid hormone to function optimally.
The amount of T4 and T3 secreted by the thyroid gland is regulated by the pituitary gland, which lies underneath your brain. The pituitary secretes thyroid stimulating hormone – TSH , which stimulates the thyroid gland to secrete T3 and T4. The pituitary senses the level of thyroid hormones in the blood, and maintains thyroid secretion in the normal range. If thyroid hormone level drops even a little the pituitary reacts by increasing the amount of TSH secreted.
Thus T4 and T3 levels are more important in thyroid disease management and treatment. Check more thyroid conditions and diagnosis methods below
