Thyroid is a gland in the neck overlying the windpipe that regulates the speed of metabolic processes by producing a hormone with the eponymous name thyroxin. Thyroid is an endocrine gland. The thyroid gland which resembles a butterfly, sits astride the trachea. Its secretion - thyroxin, a hormone that regulates the metabolic activity of the body. Too much thyroxin races the metabolism resulting in weight loss, temperature elevation, nervousness and irritability. On the other hand, too little thyroxin slows down the metabolism rate resulting in deep voice, weight gain and water retention. This can result in retardation in physical growth and mental development in children. Both conditions equally affect hair and skin growth, bowel function and menstrual flow.
The thyroid gland is often enlarged whether it is secreting too much hormone, too little or even when it is functioning normally. The thyroid is controlled by the pituitary gland, which secretes Thyroid Stimulating Hormone (TSH) in response to the amount of thyroxin in the blood. TSH increases the amount of thyroxin secreted by the thyroid and also causes the thyroid gland to grow.
Hyperthyroid Goiter : If the amount of TSH is high, the thyroid will both enlarge and secrete too much thyroxin. The result is termed as Hyperthyroidism with a goiter. Graves' disease is the most common form of this disorder.
Euthyroid goiter : If dietary iodine is insufficient, too little thyroxin will be secreted and the pituitary will sense the deficiency and produce more TSH. The thyroid gland will enlarge enough to make sufficient thyroxin.
Hypothyroid goiter: If dietary iodine is severely low, even an enlarged gland will not be able to make enough thyroxin. The gland may keep growing under the influence of TSH, but it may never make enough thyroxin.
An endocrinologist who specializes in the endocrine system can also be consulted for thyroid problems and diseases. Specialists who deal with thyroid problem are called thyroidologists. Thryoidologist and endocrinologist are specially trained doctors who diagnose and treat diseases affecting the thyroid gland. A thyroid specialist continues specialized education focused on thyroid issues after obtaining a Masters degree in medicine. He is qualified and trained to treat conditions that are complex and involve many systems within the body that may be affected due to thyroid imbalance.
A primary care doctor too often misses the diagnosis of a thyroid disease. Sometimes primary care doctors refer patients to a thyroid specialist when there is problem in the endocrine/ hormone systems. Thyroid specialists treat patients with too much or too little thyroid hormone. The thyroid specialist helps the patients to reach a hormone balance by replacing or blocking thyroid hormone. Thyroid specialists also receive special training to manage patients with thyroid growths or thyroid cancer and enlarged thyroid glands. There are times when the services of a thryoidologist or an endocrinologist become absolutely necessary.
