Iodine is referred to as a trace element, within humans used, in the synthesis of thyroid hormones. For adults the normal daily intake ranges from 0.03mg-0.15mg a day. Iodine works with the thyroid gland to produce thyroid hormones.

When there is a lack of iodine in the system the thyroid function slows down and hypothyroidism results. If the opposite occurs then one can develop hyperthyroidism. The metabolic rate increases or decreases depending upon nutritional levels within the body. Speeding up the metabolic rate can cause loss of weight and slowing down the metabolic rate can cause weight gain.

The primary cause for lack of iodine is the absence of iodine within a regular diet. Lack of iodine can cause an enlargement of the thyroid and this enlargement is called an endemic goiter.

Endemic goiters are caused by lack of iodine from the diet. These goiters are common in volcanic and mountain areas where the ground lacks sufficient iodine. Other goiters are called toxic nodular goiters and colloid nodular goiters. A colloid nodular goiter occurs when there is a deficieny of iodine in the diet. When there is too much iodine one can develop a toxic nodular goiter, from which the nodules produce excess thyroid hormones causing thyrotoxitosis.

Sometimes a person may suffer from impaired breathing ability and difficulty in swallowing, because the enlargment (the goiter) may cause compression on the trachea and the esophagus. Goiter has been the common term for the enlagement of the thryoid gland, however the current name is Iodine Deficiency Disorders or (IDD).

In the case of a pregnant woman becoming thyroid deficient, care must be taken. It is vital to her infant that treatment and diet change this condiiton, as the child can be harmed. The growing infant is in need of adequate amounts of thyroxin without, which the brain will not develop as it should. Normal levels of thyroxin is imperative for the mother and for the infant.
