Causes of hypothyroidism

Unlike hyperthyroidism, in hypothyroidism there is a deficit in the production of thyroid hormones. The main cause of this alteration of the thyroid gland is Hashimoto's thyroiditis, but hypothyroidism can also be caused by:

• Removal of the thyroid gland, either totally or partially.
• Radioactive therapies used as cancer treatment.
• Diet low in iodine.
• The administration of certain drugs such as amiodarone.
