Iodine deficiency symptoms

Iodine is needed to make thyroid hormones. Iodine is a non-metallic trace element that is essential for nutrition.
Iodine deficiency causes problems at all stages of life. Iodine is needed in the diet so that the body can produce thyroid hormones.

Thyroid hormones help develop the nervous system by aiding the formation of the myelin sheath of certain nerves in the central nervous system. These nerve sheaths form before and shortly after birth.

The damage to the brain caused by iodine deficiency is irreversible. If the deficiency is severe during pregnancy, it may result in cretinism in the child.
Iodine deficiency is the most common cause of preventable brain damage in the world. Diets that do not include seaweed, fish, iodized salt, or other iodized food have been found to contain very little iodine.
One of the earliest symptom of iodine deficiency is goiter – an enlargement of the thyroid gland. In older children and adults, goiter may be reversed with adequate intake of iodine. More severe iodine deficiency can result in hypothyroidism.
Symptoms of hypothyroidism (low levels of thyroid hormones in the blood) include dry skin, swellings around the lips and nose, mental deterioration, and a slow basal metabolic rate.
Iodine can be found in many multivitamin and multimineral supplements, usually in the form of potassium iodine.
Food sources of iodine are iodized salt, seaweed, fish.
