Thyroid is a gland which is situated at the base of the neck. When enlarged, this gland is clearly visible when the process of swallowing takes place. Being an endocrine gland, its main function is to directly secrete Thyroxin in to the blood stream. Cellular metabolism is regulated is the main function regulated by the Thyroid hormone in Humans.

Hyperthyroidism is a situation when the thyroid gland secretes too much of thyroxin.  This results in Goiter, which is the enlargement of the gland. The simple detectable symptoms of Goiter are weight loss, palpitations, increased sweating, nervousness and heat intolerance. Hypothyroidism is the decreased secretion of Thyroxin which is highly prevalent in the current female population. The common symptoms of Hypothyroidism are weight gain, dry skin and cold intolerance.

The preventive measure for the problem of Thyroid is early detection. This is usually done by the estimation of thyroid hormone i.e. T3, T4 and TSH. Sonography and radioactive scan of Thyroid is required for the accurate detection of Thyroid diseases.

Fine needle aspiration biopsy is a painless and effective method of thyroid detection and should be carried out soon. However, the best and the most widespread preventive measure for the problem of Thyroid is iodination of salt. This method is especially important in the iodine deficient areas.

Hypothyroidism can be treated simply by the oral dose of Thyroxin tablets every morning. Being a replacement therapy, this treatment does not carry any side-effects and can be carried out effectively. A dose of 50-150 microgram is required to be taken orally before breakfast. Normally, the treatment for Hypothyroidism is carried out through out life, but can be discontinued once the effect is reversed following the treatment.

The problem of thyroid demands proper control measures and maintenance. With proper treatments at the regular basis thyroid can be tamed. Thyroxin, however, is important through out the animal kingdom and is necessary for various vital processes like metamorphosis in amphibians.
