Significance of Thyroid gland in Human Body
The thyroid is the endocrine gland located at the outer covering of the pharynx or the air tract. Thyroid hormone is responsible for the production of the hormone that plays the vital part in the regulation of body metabolism.
The secretion of the endocrine gland is often known as hormones that are often known as the chemical messenger to trigger the specific biological function.
Pituitary, thyroid, parathyroid, adrenal, pancreases, testis, ovaries are the endocrine gland located in different part of the body and perform the specific function. Among them, Pituitary gland is often known as master gland as its secretion governs almost all the bodily function.
Hormone Secreted by Thyroid Gland
Two hormones are secreted from the thyroid gland. One is the Thyroxin (T4) and the other is Triiodothyronine (T3).
This is the condition marked by enlarging in the thyroid gland mainly due to insufficient iodine in the diet. Whereas exophthalmos goiter is the severe condition characterized by enlarging eyelid, neck, etc. due to false immune response.
The removal of the thyroid gland is often known as the thyroidectomy. There is the need of constant medication after the removal.
Why it is Important
The thyroid gland secretes the thyroxin hormone that has vital for the regulation of metabolism in the body. Both the high and low secretion of gland can produce upsets in the body
Less or Hypothyroidism
Less amount of thyroid secretion also known as hypothyroidism or underactive thyroid decreases the metabolic rate.
Gaining the weight, constipation, and inactive body, excessively hot and cold.
More of Hyperthyroidism.
The high amount of thyroid secretion is often known as hypothyroidism that increases the metabolic rate of the body. The Graves disease is supposed to trigger the immune system to produce the antibody which can trigger thyroid gland to release massive thyroid hormones.
Sweating, elevated heart rate, and blood pressure, weight loss, etc.
The blood test is carried out to find the level of Thyroid Stimulating hormone (TSH). The Normal range needs are 0.45 to 4.12 mlU/L. above and below this range can be considered abnormal. The endocrinologist prescribed the medication according to the severity.
Ultrasound, CT scan, radioactive iodine uptake test, the biopsy may require based on the severity.
Treatment process depends upon the severity. If the are several treatment procedures like Medication, surgery, and removal of the thyroid gland.
