Thyroid Gland Problems

The thyroid is a gland that sits low of the neck on the front of the trachea, the thyroid secretes several hormones, that act throughout the body, influencing metabolism, growth and development, and body temperature.

The thyroid gland uses iodine from the foods to make two hormones T3 and T4, thyroid hormones act throughout the body by receptors. The thyroid hormones secretion is regulated by the pituitary and hypothalamus in the brain. it is possible that symptoms will develop when a defect occurs in the previous three levels.

Women are five to eight times more likely than men to have thyroid problems, incidence risk increases with age, sometimes thyroid disorders are congenital, genetic factors have important role of thyroid disease.
