Hyperthyroidism caused by Iodine

Hyperthyroidism and Iodine

Hyperthyroidism is a condition caused by an overactive thyroid gland, resulting in excessive production of hormones such as T3 and T4. One of the most common causes of hyperthyroidism is an excess intake of iodine. Iodine is a mineral found naturally in many foods, such as shellfish, eggs, dairy, and grains. It is also added to some processed foods, such as salt and bakery products.

Although iodine is important for the proper functioning of the thyroid, too much iodine can lead to an overproduction of thyroid hormones. This can result in symptoms such as fatigue, weight loss, palpitations, and increased appetite. Other symptoms of hyperthyroidism caused by iodine can include:

  • Anxiety and irritability
  • Heat intolerance
  • Goiter (enlarged thyroid)
  • Frequent bowel movements
  • Heavy menstrual bleeding or irregular periods
  • Muscle weakness
  • Tremors
  • Hair loss

Excess iodine can be caused by taking dietary supplements, by exposure to certain medicines, or by overexposure to radioactive iodine. People with certain chronic health conditions, such as kidney or liver disease, may also be more vulnerable to developing hyperthyroidism caused by iodine.

Treatment for hyperthyroidism caused by iodine may include the use of medications or Iodine Supplements such as Lugol's Solution, Iodotope, and Neoiodized Oil. Surgery to remove part or all of the thyroid gland (thyroidectomy) may also be an option.
