  1. Autoimmune disease: The immune system shields the body and destroys the foreign antibodies, but in this condition the system mistakenly identifies the thyroid gland cells as well as its hormones as the invader cells and begins to attack them. Hence, decreasing the number of thyroid cells which can produce the thyroid hormone in the human body. This is commonly found in women compared to men. It might begin suddenly or develop gradually over the years. The most common ones are Hashimoto’s thyroiditis and atrophic thyroiditis.
  2. Surgical removal of part or all of the thyroid gland: Patients who suffer from diseases like thyroid nodules, thyroid cancer, or Graves’ disease have to undergo surgery for the removal of all or a part of the thyroid gland. When the entire gland is removed people generally become hypothyroid. And in case only a part of it is removed, then the thyroid might be able to produce as much hormone as required for maintaining the normal level in the blood stream.
  3. Radiation treatment: People suffering from diseases like Graves’ disease, nodular goiter, or thyroid cancer undergo a treatment of radioactive iodine (I-131) meant to destroy the thyroid gland. Also, the patients suffering from Hodgkin’s disease, lymphoma, or cancers of the head or neck etc. are given the radiation therapy. Such patients, be it due to radioactive iodine (I-131) treatment or radiation therapy, lose a part or all of the thyroid function.
  4. Medication: Some medicines have inhibitory effect on the production of thyroid hormone. These include amiodarone, lithium, interferon alpha, and interleukin-2.
