Iodine deficiency is a lack of the trace element iodine, an essential nutrient in our diet.
A deficiency of iodine may lead to thyroid or medical conditions.
Iodine deficiency is considered an important public health issue.
The simple answer is "it can't." That is why iodine needs to be a part of our diets.
When we are not getting enough iodine in your diet, we need to supplement as necessary.
◉ Goiter - Abnormal enlargement of the thyroid gland
"The term “goiter” simply refers to the abnormal enlargement of the thyroid gland. It is important to know that the presence of a goiter does not necessarily mean that the thyroid gland is malfunctioning. A goiter can occur in a gland that is producing too much hormone (hyperthyroidism), too little hormone (hypothyroidism), or the correct amount of hormone (euthyroidism). A goiter indicates there is a condition present which is causing the thyroid to grow abnormally."
◉ Hypothyroidism - Underactive thyroid gland
"Hypothyroidism is an underactive thyroid gland. Hypothyroidism means that the thyroid gland can’t make enough thyroid hormone to keep the body running normally. People are hypothyroid if they have too little thyroid hormone in the blood. Common causes are autoimmune disease, such as Hashimoto’s thyroiditis, surgical removal of the thyroid, and radiation treatment."
◉ Thyroiditis - Inflammation of the thyroid gland
"The term “Thyroiditis” refers to “inflammation of the thyroid gland”. There are many possible causes of thyroiditis. Hashimoto’s thyroiditis, also known as chronic lymphocytic thyroiditis, is the most common cause of hypothyroidism in the United States."
◉ Hashimoto's Thyroiditis
"Hashimoto’s thyroiditis, also known as chronic lymphocytic thyroiditis, is the most common cause of hypothyroidism in the United States. It is an autoimmune disorder in which antibodies directed against the thyroid gland lead to chronic inflammation. It is not known why some people make antibodies, although this condition tends to run in families. Over time, however, this results in impaired ability of the thyroid gland to produce thyroid hormones, leading to gradual decline in function and eventually an underactive thyroid (hypothyroidism). Hashimoto’s thyroiditis occurs most commonly in middle aged women, but can be seen at any age, and can also affect men, and children."
◉ Weight Gain - Decreased BMR (basal metabolic rate)
"Since the BMR in the patient with hypothyroidism is decreased, an underactive thyroid is generally associated with some weight gain. The weight gain is often greater in those individuals with more severe hypothyroidism."
